What the medical exam actually tests
The short answer
Underwriting usually begins with a health questionnaire and, for fully underwritten policies, a paramedical exam. The findings place an applicant into a rate class, and the rate class is what the premium is built from.1
What a paramedical exam collects
A trained examiner takes height, weight, blood pressure and a pulse, draws blood and collects a urine sample. Those samples are screened for markers that indicate cardiovascular, liver, kidney or metabolic risk, and separately for nicotine. The applicant also answers a health and lifestyle questionnaire covering conditions, medications and family history.
| Measure | What it indicates | How insurers weight it |
|---|---|---|
| Height and weight | Build relative to the range | Applied as a table, not judged alone |
| Blood pressure | Cardiovascular load | Repeated readings; treated as a trend |
| Blood panel | Cholesterol, glucose, liver and kidney markers | Differently weighted by each insurer |
| Urine screen | Kidney function, glucose, nicotine | Nicotine use moves the class sharply |
| Questionnaire | History, medication, family conditions | Read against the medical record |
Rate classes, in general terms
Classes run from the most favourable down to standard and, in some cases, substandard. The difference between the best class and standard is usually a multiple rather than a small step — which is why a single uncontrolled marker can move the whole premium.
Disclosure, and why partial answers backfire
The application is part of the contract. An answer that omits a condition, a medication or a prior diagnosis gives the insurer grounds to challenge a claim later, and the challenge usually arrives at the worst possible moment for a beneficiary.
Do not stop a prescribed medication to produce a cleaner test. The medical record shows the prescription, and the inconsistency is itself a material fact.
Time since an event
Underwriting weighs not only what happened but when. A condition treated and stable for several years is read differently from the same condition diagnosed recently, and some insurers apply a waiting period before the most favourable classes become available again.
Where the rules differ
State insurance regulation governs disclosure requirements, contestability windows and replacement notices, and the length of those windows differs by state. Confirm the rules where you live before cancelling an existing policy to apply for a new one.
