# The Pre-Expat Health Audit: Tests You Need Before You Go

Americans relocating abroad discover chronic conditions during their first year at 3x the rate of those who completed baseline diagnostics before departure. This gap can transform a planned retirement into an unexpected medical bill. Yet most relocation guides treat health planning as a box to check after visas are approved and flights are booked.

The strategic move: complete your preventive medical checkup before leaving the US while you still have full insurance coverage, consolidated medical records, and immediate access to specialists. A comprehensive pre-departure health audit takes 8–12 weeks and costs $2,000–$5,000. Discovering a missed diagnosis abroad can cost 10x that, delay your relocation by months, and force you to navigate unfamiliar healthcare systems under pressure.

This guide covers the specific tests, timelines, and country-specific strategies you need to relocate with confidence.

## Why a Pre-Departure Health Audit Matters

Completing a medical checkup before moving abroad is fundamentally about strategy, not just cost. In the United States, you have consolidated medical records, comprehensive insurance coverage for preventive screening, and easy access to specialists. Once you relocate, that infrastructure disappears.

Foreign healthcare systems, even excellent ones like Portugal's NHS-equivalent or Spain's public system, operate differently. They require new patient registrations, may not have your complete medical history, and often don't cover the same breadth of preventive diagnostics Americans expect. Out-of-pocket costs for screening abroad are substantial: a full cardiac workup (ECG, stress test, echocardiogram) costs $400–$800 in the US with insurance but $1,200–$2,500 out-of-pocket in Portugal or Mexico. A colonoscopy runs $500–$800 in the US with insurance; $1,500–$2,500 in private clinics abroad.

More importantly, discovering a health issue after you've moved requires managing it across borders: coordinating with US specialists remotely, arranging imaging or follow-up testing in an unfamiliar healthcare system, and potentially returning to the US for treatment. These scenarios aren't rare. Uncontrolled hypertension, undiagnosed diabetes, thyroid dysfunction, and sleep apnea commonly surface for the first time in expats who assumed they were healthy because they hadn't had recent screening.

Completing a comprehensive pre-departure health audit establishes a baseline, identifies issues while US system resources are available, and builds a digitized medical record that travels with you.

## The Baseline Diagnostics Checklist

The specific tests you need depend on your age, family history, and existing health conditions. However, certain screenings apply broadly and should be completed before any international move.

### Core Screening for All Ages

**Blood Work** ($200–$400 with insurance)
- Complete metabolic panel (glucose, kidney function, liver function, electrolytes)
- Lipid panel (cholesterol, LDL, HDL, triglycerides)
- Complete blood count (CBC)
- Thyroid function (TSH, free T4)
- Hemoglobin A1C (diabetes screening)
- Vitamin levels (B12, D, iron) — especially relevant if you'll relocate to lower-sunshine destinations like Portugal

These tests establish your metabolic baseline and catch early-stage conditions like diabetes, hypothyroidism, and anemia before they become symptomatic.

### Age 35–50

**Cardiovascular Screening**
- Resting ECG ($100–$300 with insurance)
- Blood pressure monitoring (at least 3 readings over 2 weeks to establish true baseline)
- Consider a stress test if family history of early cardiac disease exists

**Cancer Screening**
- Colonoscopy if you're turning 45 (updated recommendations from [the American Cancer Society](https://www.cancer.org/cancer/colorectal-cancer/detection-diagnosis-staging/colorectal-cancer-screening-guidelines.html)); otherwise at 50
- Women: mammogram starting at 40–50 (institution-dependent); Pap smear if applicable
- Men: prostate screening discussion with your doctor (PSA test is optional and should be an informed decision)

**Preventive Imaging**
- Baseline chest X-ray if you have any respiratory history or are a former smoker

### Age 50–65

All screening from the 35–50 cohort, plus:

**Cardiovascular Risk Assessment**
- Carotid ultrasound if you have risk factors (smoking history, hypertension, high cholesterol, family history of stroke)
- Ankle-brachial index (ABI) test if peripheral vascular disease is a concern

**Metabolic and Bone Health**
- DEXA scan (bone density) for women and men over 70 or with risk factors
- Advanced lipid panel including Lp(a) and apoB if cardiovascular risk is moderate to high

**Cancer Screening**
- Colonoscopy every 10 years (or sooner if findings warrant)
- Annual mammogram for women; prostate screening discussion for men
- Lung CT screening if you have >20 pack-year smoking history

### Age 65+

All previous screening, plus:

**Cognitive and Neurological**
- Baseline cognitive assessment (Montreal Cognitive Assessment or similar) for future comparison and early detection of decline
- Consider an EEG if you have any neurological symptoms or family history of dementia

**Advanced Cardiovascular**
- Calcium score CT if not previously done (predicts coronary artery disease risk)
- Echocardiogram if you have any cardiac history or murmurs

**Additional Screening**
- Abdominal aortic aneurysm ultrasound if you're a former or current smoker and age 65–75
- Thyroid ultrasound if you have any nodules or family history of thyroid cancer

**Why This Matters for Expats**: These baseline tests create a reference point for foreign doctors. If you develop a health issue abroad, your physician will compare current findings to baseline imaging and labs from the US. Without these, you're starting from zero—often requiring expensive diagnostic repeats.

### The Real-World Timeline

Scheduling these tests takes time. A typical baseline audit follows this pattern:

- **Week 1–2**: Schedule all tests. Many require 2–4 week wait times.
- **Week 3–6**: Complete blood work, imaging, and non-specialist tests (ECG, X-ray, DEXA, etc.).
- **Week 7–10**: Receive results and meet with your primary care doctor to review findings.
- **Week 11–12**: If any findings require follow-up (abnormal lipids, blood pressure, or imaging), schedule specialist consultations.

If you want to move in 12 weeks, you should start this audit now.

## Prescription Audit: What to Source Before You Go

One of the most overlooked aspects of preparing for a move abroad is a medication inventory and sourcing strategy. American prescriptions don't transfer internationally because of regulatory differences and because you won't have a prescriber in your destination country.

### The Pre-Departure Medication Strategy

Before you leave the US, you should:

1. **Obtain a written list from your prescriber(s)** that includes generic names, dosages, and frequencies for every medication you take.
2. **Confirm availability in your destination country** using pharmacy checks or online resources.
3. **Secure a 6–12 month supply** from US pharmacies before departure (legal for personal use if quantities are reasonable).
4. **Obtain medical summaries and prescriptions from your doctors** that explain why you take each medication, useful for foreign doctors who may not recognize certain drugs by brand name.

### Medication Sourcing by Destination

Not all medications are equally available or legal in every destination. Common American medications like statins, antihypertensives, and levothyroxine are widely available in Spain, Portugal, Mexico, and Thailand. Psychiatric medications, biologics (monoclonal antibodies for autoimmune disease), and controlled substances face stricter regulations.

**Antihypertensives (ACE inhibitors, beta-blockers, calcium channel blockers)**: Widely available in all major destinations. Cost abroad is often lower than US prices. **Strategy**: Bring 3–6 months from the US; source locally once you confirm availability and cost.

**Statins and Lipid-Lowering Drugs**: Available everywhere. Cost varies—$20–$50/month in Mexico, €10–€30/month in Portugal. **Strategy**: Source from destination pharmacy; bring 6 months from US as backup.

**Thyroid Hormones (Levothyroxine, Synthroid)**: Available in all destinations. Confirm that your destination pharmacy carries your preferred formulation (brand vs. generic) since switching can affect absorption. **Strategy**: Bring a full year supply from the US; local sourcing is reliable once confirmed.

**Psychiatric Medications (SSRIs, SNRIs, antipsychotics, benzodiazepines)**: Complexity increases here. SSRIs and SNRIs are available in most destinations but may be under different brand names. Benzodiazepines face tighter controls in many countries. Some psychiatric medications (like certain mood stabilizers) are restricted or require specialist authorization. **Strategy**: Confirm with your psychiatrist or primary care doctor what's available in your destination. Obtain a letter explaining your diagnosis and medication necessity. Bring a full 12-month supply from the US if your destination has restrictions.

**Biologics (Humira, Enbrel, Dupilumab, etc.)**: These injectable or infused medications require specialist management and are expensive. Availability depends entirely on your destination country's healthcare system. In Portugal, biologics for autoimmune disease are covered by the public system but require specialist authorization. In Mexico, they're available privately but cost $2,000–$5,000/month. In Thailand, some biologics are available; others require import permits. **Strategy**: Before you move, confirm with a rheumatologist or specialist in your destination whether your specific biologic is available and how it's sourced (public system, private pharmacy, import). If sourcing is complicated, bring a 3–6 month supply and plan your first specialist consultation to arrange longer-term supply.

**Controlled Substances and Stimulants (Adderall, Ritalin, Modafinil)**: Highly restricted in most countries outside North America. Thailand has strict laws around amphetamine-class medications. Mexico allows limited quantities for personal use but requires special documentation. Portugal and Spain have more flexibility but still require local prescriptions. **Strategy**: Do not assume you can bring a year's supply. Contact the US embassy in your destination country for specific guidance on importing controlled substances for personal use. Work with your doctor to obtain a detailed medical letter and prescription. Plan to establish care with a local psychiatrist or neurologist early in your move to arrange ongoing prescriptions.

### Securing a 6–12 Month Supply

Federal law allows Americans to import a personal supply of medications for personal use without a pharmacy license. Practical limits apply:

- **Quantities**: Generally, a 90-day supply is considered reasonable for personal use. For longer timelines (6–12 months), some customs officers may question it, though personal medical need usually prevails. Frame it as: "I'm relocating internationally and establishing care will take 2–3 months; I want to ensure continuity."
- **Documentation**: Keep prescription copies, doctor's letters, and a handwritten medication list in your luggage.
- **Packaging**: Medications must remain in original labeled containers from a US pharmacy, not transferred to unmarked bottles.

Many expats use a two-phase strategy:

1. **Phase 1 (Months 1–3 of relocation)**: Live on the 6–12 month supply from the US, giving yourself time to find doctors, establish prescriptions, and source medications locally.
2. **Phase 2 (Month 4+)**: Transition to locally sourced medications once you've confirmed availability, cost, and a reliable provider relationship.

This approach eliminates the stress of figuring out medication logistics in your first weeks abroad.

> **Understand your destination's healthcare system and insurance options.** Once you've completed your health audit and secured your prescriptions, you'll need to know what healthcare costs and coverage look like in your destination.

## Specialist Consultations by Destination Type

The healthcare infrastructure of your destination determines what specialist care is realistically available and when you should complete certain consultations before departure.

### Destinations with Excellent Specialist Care: Portugal, Spain, and Mexico

Portugal, Spain, and Mexico all have robust private healthcare systems with board-certified specialists. If you're relocating to Lisbon, Madrid, Barcelona, or Mexico City, most specialist care is accessible and often high-quality.

**What to do pre-departure**: If you have a chronic condition requiring specialist management (hypertension, diabetes, coronary artery disease, autoimmune disease), have a detailed consultation with your US specialist before you go. The goal is not to complete all treatment but to establish:

- A clear diagnosis and management plan
- Current test results and imaging that a foreign specialist can reference
- A written summary of your condition and current medications
- A plan for how often you should see a specialist abroad (every 6 months, annually)

Example scenario: You have controlled hypertension managed by a cardiologist. Before moving to Spain, schedule a final appointment with your US cardiologist. Confirm your blood pressure target, get a current EKG and possibly an echocardiogram, and obtain a written summary of your condition. In Madrid, finding a cardiologist (cardiólogo) is straightforward—private practitioners charge €100–€200 per visit. Your US documentation accelerates the process because the Spanish cardiologist doesn't start from zero.

### Destinations with Intermediate Specialist Care: Costa Rica, Panama, and Colombia

Costa Rica, Panama, and Colombia have good healthcare infrastructure in major cities, but specialist availability can be more variable. Some specialists are excellent; others may be less experienced with certain conditions.

**What to do pre-departure**: Complete all diagnostic workup in the US. If you have a complex condition, consider having your US specialist email your destination doctor before you arrive, or plan for telemedicine follow-ups with your US provider during your first year abroad.

Example scenario: You have mild sleep apnea managed with a CPAP machine. Before moving to Panama, have your US sleep specialist prescribe your current settings and provide a detailed sleep study report. In Panama City, you'll find sleep specialists, but finding one quickly as a new resident is harder. By arriving with documentation and a working CPAP machine, you buy yourself time to find a local provider for routine follow-up.

### Destinations with Limited Specialist Infrastructure: Thailand and Philippines

Thailand and the Philippines have pockets of excellent healthcare in Bangkok and Manila respectively, but outside major cities, specialist care is limited. Medical tourism is standard—many Thais and Filipinos travel to Bangkok or Manila for specialty work.

**What to do pre-departure**: Complete all major diagnostic work and any procedures you anticipate needing in the US. Plan for at least some telemedicine follow-up with US specialists during your first 1–2 years.

Example scenario: You have a minor cardiac arrhythmia that's stable on medication but requires monitoring. Before moving to Thailand, have your US cardiologist document your condition thoroughly and provide a copy of your most recent EKG and echo. You can find cardiologists in Bangkok (at Bumrungrad or Bangkok Hospital), but telemedicine follow-up with your US cardiologist—which costs $150–$300 per visit—may be your more reliable option for complex decision-making.

## Dental and Vision: Do It Now

Dental and vision care are time-sensitive, often cheaper abroad, but logistically complex to manage across borders. Complete both before you move.

### Dental Work

The cost difference between the US and common expat destinations is significant:

- **Root canal**: US $1,000–$1,500; Mexico $400–$700; Portugal €600–€1,000
- **Crown**: US $800–$1,500; Mexico $300–$600; Portugal €500–€900
- **Implant**: US $3,000–$6,000; Mexico $1,200–$2,500; Portugal €1,500–€3,000

The cost advantage of dental work abroad is real. However, timing crowns, implants, and follow-up care across borders is genuinely complex. If a crown falls off or an implant becomes infected two weeks after you've moved to Mexico, you're managing it with a dentist you just met.

**Strategy**:

1. **Get a comprehensive dental exam in the US** (if you haven't had one in over a year). Cost: $100–$200. This includes full mouth X-rays and a written assessment of needed work.
2. **Complete all urgent and medium-term work in the US**. This includes root canals, extractions, and crown prep. Budget $1,500–$5,000 depending on what's needed.
3. **Delay elective cosmetic work or non-urgent implants until you're settled abroad**. Once you've been in your destination country for 3–6 months and found a dentist you trust, you can pursue major cosmetic or implant work at a fraction of US cost.
4. **Obtain digital X-rays and a written summary** of your dental status from your US dentist. Bring these to your destination dentist—it provides continuity and may mean they don't re-X-ray your entire mouth.

This approach reserves urgent care for dentists

## Frequently Asked Questions

### How far in advance should I schedule my medical checkup before moving abroad?

Schedule your health audit 2–3 months before your planned departure date, which gives you time to address any findings, obtain copies of records, and arrange follow-up care if needed. This timeline is especially important if you require specialist referrals or need to complete vaccinations that require multiple doses spaced weeks apart.

### What's the typical cost of a comprehensive pre-expat health screening in the US?

A full preventive care audit including blood work, imaging, and specialist consultations typically ranges from $1,500–$3,500 depending on your age, existing conditions, and which tests are included. Many insurance plans cover routine preventive care at no cost, though specialty tests or imaging may require out-of-pocket spending. Expat Countdown's resource guides can help you understand what's usually covered under different plan types before you leave.

### Should I get dental and vision work done before moving abroad or wait until I arrive?

It's generally wise to complete major dental work and get a fresh pair of prescription glasses or contact lenses before you go, since finding reliable dentists and optometrists in a new country takes time and may be more expensive initially. Minor cleanings and vision checkups can often wait, but addressing cavities, root canals, or outdated prescriptions beforehand eliminates the stress of finding care during your transition period.

### What vaccinations do I need beyond my standard immunizations for moving abroad?

Vaccination needs depend entirely on your destination country and current health status—some regions require yellow fever or typhoid boosters, while others have different risk profiles. Contact your destination country's health ministry or visit the CDC's travel health page 4–6 weeks before departure to get a personalized list, since requirements vary significantly by location.
