Medical examinations and lab work
Most insurers require a physical exam performed by a licensed paramedical professional. They measure height, weight, blood pressure, and heart rate, and draw blood and urine samples. The lab results reveal cholesterol levels, blood sugar, liver and kidney function, and the presence of substances such as nicotine or illicit drugs. Abnormal values can raise the risk rating, leading to higher premiums or exclusions.

Health questionnaires and medical history
Applicants fill out a detailed questionnaire covering past and current illnesses, surgeries, hospitalizations, and family medical history. Conditions like heart disease, cancer, diabetes, or severe mental health disorders are flagged because they statistically increase the likelihood of a claim. Even seemingly minor issues—such as frequent migraines or a history of asthma—may affect the underwriting decision.
Prescription and medication review
Insurers request a list of all prescription and over‑the‑counter medications you take. Certain drugs, especially those for chronic conditions (e.g., insulin, anticoagulants, chemotherapy agents), signal higher risk. Conversely, a stable regimen of routine medications can demonstrate ongoing medical management, which some carriers view favorably.
Lifestyle and habit assessment
How you live impacts your risk profile. Underwriters look at:
- Smoking status—current, former, or never smoked.
- Alcohol consumption—frequency and quantity.
- Recreational drug use.
- Exercise habits and overall fitness level.
- Occupational hazards—jobs involving heavy machinery, high altitudes, or frequent travel.
Riskier habits typically result in higher rates or policy exclusions.
Financial and credit evaluation
While not a medical test, many carriers run a credit check. A strong credit history suggests financial responsibility and lower lapse risk, whereas poor credit may lead to higher premiums or a denial.
Optional supplemental testing
Depending on age, coverage amount, or red‑flag answers, insurers may order additional diagnostics such as:
- Electrocardiogram (EKG) for heart rhythm assessment.
- Stress test to evaluate cardiac endurance.
- Imaging studies (X‑ray, MRI) for specific complaints.
- Genetic testing—rarely required, but sometimes requested for hereditary conditions.
Comparing underwriting approaches
| Underwriting style | Typical tests | Impact on premium |
|---|---|---|
| Full medical underwriting | Physical exam, lab work, detailed questionnaire | Most accurate risk rating; can be higher or lower |
| Simplified issue | Short health questionnaire, no exam | Generally higher baseline premium; faster approval |
| Guaranteed issue | None required | Highest premiums; limited coverage amounts |
How to prepare for underwriting
Schedule any pending doctor appointments, gather past medical records, and be honest on the questionnaire. Disclose all medications and lifestyle habits; omissions often lead to claim denial later. If you smoke, consider quitting several weeks before the exam to improve results. Maintaining a healthy weight, balanced diet, and regular exercise can positively influence blood‑test outcomes.
What happens after the test results
The underwriting team reviews all data and assigns a risk class—often labeled Preferred, Standard, or Substandard. Preferred rates are offered to those with optimal health markers, while Substandard may carry rating factors (e.g., 1.5× or 2× the standard premium). In some cases, insurers issue a conditional offer pending further clarification or additional testing.
