What a life insurance blood and urine test looks for
What insurers test for in the blood and urine samples taken at a life insurance exam: cholesterol, glucose, liver and kidney markers, nicotine and drugs.
The blood and urine samples collected at a life insurance exam are tested for markers of heart disease risk, diabetes, liver and kidney function, nicotine and other substance use, and, in many cases, HIV and other infections. The lab sends the results to the insurer's underwriter, who uses them with your application and other records to set your rate class. You can usually get a copy of the lab report by asking the insurer or your agent.
Panels differ by insurer, age and coverage amount, so the list below describes common practice, not a fixed standard. Smaller policies for younger applicants may use a shorter panel.
What the lab typically measures
| Test | What it can signal | Why it matters to pricing |
|---|---|---|
| Total cholesterol, HDL, LDL, triglycerides | Cardiovascular risk | Ratios, especially total to HDL, feed risk models for heart disease (see life insurance with high cholesterol) |
| Glucose, and often hemoglobin A1c | Diabetes or prediabetes; A1c reflects about the past three months | Elevated values suggest diabetes risk or poor control (see life insurance with type 1 or type 2 diabetes) |
| Liver enzymes (such as ALT, AST, GGT) | Liver inflammation or damage, heavy alcohol use, some medications | Abnormal readings can lead to a follow-up or a rating |
| Kidney markers (creatinine, and protein or blood in urine) | Kidney function, diabetes or blood pressure complications | Linked to long-term mortality risk |
| Cotinine (urine, blood or oral fluid) | A nicotine metabolite | Distinguishes tobacco and nicotine users from nonusers |
| Drug screen | Non-prescribed drugs, sometimes prescribed drugs | Positive tests for illicit drugs often lead to decline or postponement |
| HIV antibody test | HIV infection | Applications for larger amounts commonly include it, and positive results are handled under state consent and disclosure rules |
| Hepatitis markers, in some panels | Hepatitis B or C | See Life insurance with hepatitis C |
Some insurers add other items, such as a PSA test for older men or NT-proBNP, a heart marker, for older applicants. Whether a test is included depends on the amount of coverage and age, and insurers differ on this.
Nicotine testing
Cotinine tests are why smoking cannot be concealed. Cotinine can remain detectable for a few days after the last use, and the insurer's own policy about the lookback and what it counts matters. Many insurers treat cigars, vaping, nicotine gum and patches differently, so the same result can be priced differently at two companies. The vaping, nicotine pouches and life insurance rates and life insurance for smokers guides cover these differences. Marijuana is handled separately by each insurer (see marijuana use and life insurance).
Fasting and why it matters
Glucose and triglycerides rise after eating, so labs usually prefer a fasted sample. If you eat before a test that needs fasting, your readings may be inflated and the underwriter may order another test. Fasting guidance is given when you schedule, and it generally allows water.
What happens if a result is abnormal
An abnormal value is a flag, not a verdict. Underwriters typically respond in one of four ways:
- Accept it as is. A small excursion that does not change the class.
- Request records. An attending physician statement from your doctor shows whether the value is known, treated or a one-time reading.
- Order a retest. Especially for a nonfasting sample or an outlier.
- Adjust the offer. A lower rate class, a table rating, or a postponement while a problem is evaluated.
Where a test result comes from a documented condition that is well controlled on treatment, underwriters usually weigh how long it has been stable, not only the number on the lab sheet.
Medications can change the picture
Taking cholesterol, blood pressure or diabetes medications can bring lab numbers into the normal range. Insurers do not ignore the underlying diagnosis for that reason, but a controlled reading with documentation is better than an uncontrolled one. Your prescription history will also be pulled from pharmacy databases, so lab and prescription data are cross-checked (see how insurers check your prescription history).
Your rights to the results
The lab is working for the insurer, but the findings are about you. Insurers are generally required by state privacy rules to give you the opportunity to learn if an adverse decision was based on test results, and many will tell you the reason for a rating. Ask your agent or the insurer for the exam results; some applicants are also contacted when a result suggests a medical problem worth discussing with their own doctor. A significant finding, such as markedly elevated glucose, is worth a follow-up with your physician regardless of what happens with the policy.
Information with underwriting significance may be reported to the MIB (see The MIB report: what insurers know about your history), which is separate from the lab report.
A hypothetical example
Say a 40-year-old applicant has a fasting glucose reading that is mildly elevated, and no diabetes diagnosis on the application. The underwriter might order an A1c test or request the doctor's records. If the doctor's chart shows a normal A1c and the reading came after a sugary breakfast, the file may proceed at the class applied for. If the A1c is also elevated, the insurer may treat the applicant as having prediabetes or undiagnosed diabetes and adjust the class. The same number can lead to different outcomes depending on the surrounding evidence and the insurer's guidelines.
If you disagree with the result
- Ask which finding drove the rate class.
- If a result was a one-off, ask your doctor for a retest and records showing the trend.
- Another insurer's guidelines may treat the same number differently, so compare offers.
- After lifestyle changes or treatment, you can ask for a better class later (see asking for a better rate class later).
Key takeaways
- Blood and urine tests commonly cover cholesterol, glucose or A1c, liver and kidney markers, nicotine and drug screens, and often HIV.
- Panels vary by insurer, age and coverage amount; smaller policies may test less.
- A single abnormal value usually triggers questions or a retest, not an automatic decline.
- Cotinine testing means nicotine use shows up even when it is not disclosed.
- You can ask for the results, and a better class may be possible later after treatment or lifestyle change.
