Home medical tests offer convenience and control over monitoring health, but their reliability and effectiveness vary. Here’s a detailed breakdown to help you decide which tests to use, what to avoid, and how to maximize their benefits.

Reliable Home Medical Tests

FDA-Approved Tests
- Examples: Blood pressure monitors, blood glucose meters, COVID-19 self-tests, HIV tests.
- Use Case: Monitoring chronic conditions (diabetes, high blood pressure) or diagnosing straightforward issues (UTIs, vaginal yeast infections).
- Benefit: Saves time, can facilitate telemedicine consultations for quicker care.

Screening Tests
- Examples: Fecal tests for colon cancer, blood tests for hepatitis C.
- Why They Work: Often reviewed by the FDA, reliable for their intended purpose with appropriate follow-up.

COVID-19 Self-Tests
- Recommendation: Use before gatherings with people outside your household to minimize virus spread risks.

Tests to Approach with Caution

Unregulated "Wellness" Tests
- Measure metrics like hormone levels, food sensitivities, or “cell aging.”
- Concern: Lax regulation and unsupported claims.
- Example: IgG food sensitivity tests, which lack evidence linking IgG levels to allergies or intolerances.

Genetic Tests for Health Risks
- Issue: Can’t definitively predict conditions like Alzheimer’s or cancer; often increase anxiety without actionable insights.

Lab-Developed Tests (LDTs)
- Examples: Tests for stress, vitamins, and general health marketed as “FDA registered.”
- Reality: FDA may not have reviewed these; reliability is questionable.

Before You Buy a Home Test

Check FDA Authorization
- Look for approval or clearance by the FDA.
- For lab tests, ensure the lab is CAP accredited or CLIA certified for quality standards.

Consult Your Doctor
- Why: Your doctor may recommend a better alternative or interpret results within the context of your medical history.

Follow Instructions Carefully
- Time of day, food/drink, and supplements can affect accuracy.

Be Aware of Expiration and Storage
- Many tests are sensitive to temperature and humidity.

Drawbacks to Keep in Mind

Confusing Results
- Many tests provide incomplete or unclear results, leading to unnecessary worry or follow-up.

Cost
- Most at-home tests aren’t covered by insurance and can be expensive, ranging from $10 to $1,000+.

Limited Accuracy
- Rapid-result COVID-19 tests, for example, are less sensitive than lab-based tests.
