Life insurance companies test for a wide range of health markers, substances, and risk factors during the application process. The standard medical exam includes blood and urine samples that screen for everything from cholesterol and blood sugar to nicotine, HIV, and illegal drugs. But the testing goes well beyond what happens in the exam room. Insurers also pull data from prescription databases, motor vehicle records, and even your credit history to build a complete risk profile.
What Happens During the Physical Exam
A paramedical examiner (usually a nurse or technician who comes to your home) takes four basic measurements: height, weight, blood pressure, and pulse. These numbers are converted into a BMI score and compared against the insurer’s build chart. For reference, a 5’10” applicant typically needs to weigh under 200 pounds for the best “preferred plus” rates, under 210 for “preferred,” and under 268 for standard rates. Being significantly underweight raises flags too. A BMI below 16 at any age results in a decline.
Applicants over 50 may need an electrocardiogram to check heart rhythm and electrical activity. Applicants over 70 may also be given a cognitive screening test.
Blood Test Markers
The blood draw is the most information-rich part of the exam. Insurers are looking at a composite picture of your metabolic, cardiovascular, liver, and kidney health. The key markers include:
- Cholesterol panel: total cholesterol, HDL (“good” cholesterol), and the ratio between them. A high cholesterol-to-HDL ratio signals cardiovascular risk.
- Blood sugar control: fructosamine or HbA1c, which reflects your average blood sugar over the past two to three months. Most insurers want an A1c below 7.0 for standard rates if you have diabetes, though some carriers accept levels up to 7.5 or even 8.0 with otherwise excellent health.
- Liver enzymes: AST, ALT, alkaline phosphatase, and GGT. Elevated levels can indicate heavy alcohol use, liver disease, or medication side effects.
- Kidney function: estimated glomerular filtration rate (eGFR), calculated from creatinine levels, tells insurers how well your kidneys are filtering waste.
- Albumin and globulin: protein levels that reflect overall nutritional status and immune function.
- HIV screening: a standard part of nearly every life insurance blood panel.
- Hepatitis screening: typically checks for hepatitis B and C.
- PSA (prostate-specific antigen): generally tested in males age 50 and older as a marker for prostate issues.
- Heart stress markers: some insurers test NT-proBNP, a protein released when the heart is under strain. Levels above 125 pg/mL in a non-acute setting can indicate heart failure risk.
Insurers don’t evaluate any single marker in isolation. They score them as a composite, so one slightly elevated number alongside otherwise healthy results may not affect your rate class at all.
Urine Test Screening
Your urine sample serves double duty: it checks for health conditions and screens for substances. On the health side, insurers look at the protein-to-creatinine ratio and albumin levels in your urine, which can reveal early kidney damage. Red blood cell counts in urine may signal kidney or bladder problems.
On the substance side, urine testing is where nicotine and drug screening happens.
Nicotine and Tobacco Detection
Nicotine use won’t get your application declined, but it will significantly raise your premiums. Smokers typically pay two to three times more than nonsmokers for the same coverage. Insurers test for cotinine, a byproduct your body produces when it processes nicotine. This catches cigarettes, cigars, vaping, nicotine patches, and chewing tobacco.
Cotinine clears from urine within three to four days after you stop using tobacco products. However, most insurers require you to be tobacco-free for 12 months before they’ll offer nonsmoker rates, and they’ll ask directly on the application. Lying about tobacco use is considered material misrepresentation and can void your policy.
Drug Screening
Life insurance drug panels typically screen for a broad list of substances. The specific drugs tested include:
- Cocaine: one of the most commonly screened substances and an automatic decline if detected
- Amphetamines and methamphetamine
- Opiates: including heroin, morphine, oxycodone, and hydrocodone
- Marijuana: policies vary by insurer, and some carriers are relatively lenient about cannabis use
- Benzodiazepines: commonly prescribed for anxiety, these won’t necessarily cause a decline if you have a valid prescription
- Barbiturates
- Methadone
- PCP (phencyclidine): an automatic decline
- Anabolic steroids
Prescription medications that show up on a drug screen aren’t automatically disqualifying. If you have a legitimate prescription for benzodiazepines or opioid pain medication, the underwriter will factor that into your overall health profile rather than treating it as a red flag on its own. Illicit drug use, particularly cocaine, heroin, or PCP, results in an immediate decline.
What Insurers Check Beyond the Exam
The medical exam is only one piece of the underwriting puzzle. Insurers routinely pull data from several external sources to verify what you’ve disclosed and uncover risks you may not have mentioned.
Your MIB (Medical Information Bureau) file is one of the first things they check. The MIB is an industry database where insurers share coded information about prior applications. If you were declined by another company or reported a serious health condition on a previous application, it will show up here.
Prescription history databases reveal every medication you’ve filled at a pharmacy, often going back five to ten years. This tells underwriters about conditions you may not have listed on your application, from antidepressants to blood pressure medication to diabetes drugs.
Motor vehicle reports show DUI convictions, reckless driving charges, and license suspensions, all of which signal risk-taking behavior. Credit-based attributes are also used by some carriers, not as a credit check in the traditional sense, but as a data point in predictive models.
No-Exam Policies Use Different Data
Accelerated underwriting programs skip the blood and urine tests entirely, relying instead on a growing list of digital data sources. According to the National Association of Insurance Commissioners, these models may draw on prescription history, digital health records, credit attributes, public records (including court filings and property data), motor vehicle reports, and even data from wearable fitness devices or smartphone apps.
Some carriers also use biometric data like voice analysis or facial analysis during the application process. Marketing and social data, including shopping habits, mortgage information, and occupation details, can factor into risk models as well. The tradeoff for skipping the exam is that insurers cast a wider net through these alternative data sources, and coverage amounts for no-exam policies are often capped lower than traditional policies.
How to Prepare for the Exam
Ask the examiner whether you should fast for eight hours before the appointment, as this produces the most accurate cholesterol and blood sugar readings. Skip coffee the morning of your exam, since caffeine can temporarily raise your blood pressure. In the week leading up to the test, drink plenty of water. Staying well hydrated helps produce a cleaner urine sample and makes the blood draw easier.
Avoid heavy exercise for 24 hours before the exam, as intense workouts can temporarily elevate liver enzymes and protein levels in urine. If you take prescription medications, continue taking them as normal. The insurer will see your prescription history regardless, and skipping doses could actually produce abnormal results that raise more questions than they answer.
