What a life insurance blood test actually measures

A life insurance blood test looks for conditions that affect how long you're likely to live and how much risk you pose to the insurance company. The test checks your cholesterol, blood sugar, liver and kidney function, and whether you have HIV or hepatitis. It also measures nicotine to verify whether you smoke — which changes your premium category. The insurer isn't looking for a reason to deny you; they're pricing the risk you represent.

The specific tests vary by the coverage amount you're requesting. A $250,000 policy might need only basic bloodwork. A $1 million policy typically requires a more complete panel. Some insurers also order an EKG or stress test if you're over a certain age or if your initial results raise questions.

Key Takeaways

  • Life insurance blood tests measure cholesterol, blood sugar, liver and kidney function, and screen for HIV and hepatitis — not to deny you coverage, but to set your premium rate.
  • The test also detects nicotine use, which moves you into a smoker rate category that costs roughly twice as much as a non-smoker rate.
  • Higher coverage amounts trigger more extensive testing; a $250,000 policy may need only basic labs, while a $1 million policy requires a fuller panel.
  • Results that fall outside normal ranges don't automatically disqualify you — they typically result in a higher premium or a rating that reflects your actual health status.
  • You can see your test results; the insurance company must provide them to you, and you have the right to dispute them if you believe they're wrong.

Cholesterol and triglycerides

The insurer measures total cholesterol, HDL (the protective kind), LDL (the kind that builds up in arteries), and triglycerides. High cholesterol increases your risk of heart attack and stroke, which are leading causes of death among life insurance holders. The insurer wants to know whether your cholesterol is controlled by medication or diet, or whether it's elevated and untreated.

If your cholesterol is high but you're already taking a statin, that's usually less concerning than high cholesterol with no treatment. The test result itself matters less than what it signals about your overall cardiovascular risk. If your numbers are borderline, the insurer may ask for a follow-up test in a few months or may simply charge you a higher premium.

Blood sugar and diabetes screening

The test measures fasting glucose and sometimes hemoglobin A1C, which shows your average blood sugar over the past three months. Diabetes — especially uncontrolled diabetes — significantly shortens life expectancy and increases the risk of heart disease, kidney failure, and stroke. An insurer needs to know whether you have diabetes, whether it's diagnosed, and whether it's well-managed.

If you have prediabetes (fasting glucose between 100 and 125 mg/dL), you may still get standard rates, but the insurer will note it. If you have diagnosed diabetes with an A1C above 8 or 9, you'll likely pay a higher premium. If your diabetes is controlled and your A1C is below 7, your rate may be only slightly higher than standard.

Liver and kidney function tests

The blood test includes markers for liver and kidney function — enzymes like ALT and AST, bilirubin, creatinine, and blood urea nitrogen (BUN). These organs filter waste and process medications. If they're not working well, it affects how your body handles drugs, alcohol, and other substances, and it signals underlying disease.

Elevated liver enzymes can indicate hepatitis, fatty liver disease, or heavy alcohol use. Elevated creatinine or BUN suggests kidney disease. Either one raises your mortality risk. The insurer uses these results to assess not just your current health, but how well your body can manage stress and illness over time.

HIV and hepatitis screening

Most life insurance blood tests include screening for HIV and hepatitis B and C. These are chronic conditions that, even with modern treatment, reduce life expectancy and increase the risk of serious complications. An insurer needs to know your status because it directly affects your mortality risk.

If you test positive, you won't automatically be denied coverage. Many insurers will issue a policy at a higher rate or with specific exclusions. Some insurers specialize in coverage for people with HIV or hepatitis. The key is being honest on your application — if you know you have one of these conditions and don't disclose it, the insurer can deny a claim later if they discover the omission.

Nicotine detection and smoking status

The blood test includes a nicotine screen, which detects whether you've used tobacco, vaping products, or nicotine replacement therapy in the past few days. This is one of the most consequential results on the test. Smokers pay roughly double the premium of non-smokers for the same coverage, because smoking dramatically increases the risk of heart disease, stroke, cancer, and COPD.

The insurer doesn't care whether you smoke cigarettes, cigars, pipes, or vape. Any nicotine use moves you into the smoker category. If you quit smoking and want to reapply as a non-smoker, most insurers require a nicotine-free period — typically one to three years — before they'll offer non-smoker rates. The blood test is how they verify your claim.

What happens if results are abnormal

An abnormal result doesn't mean you'll be denied coverage. It means the insurer will adjust your premium to reflect your actual risk. Someone with controlled high blood pressure might pay 10 to 25 percent more than standard rates. Someone with uncontrolled diabetes or a history of heart disease might pay 50 to 100 percent more. Someone with a serious condition like advanced cancer or untreated HIV might be declined, or offered coverage at a very high rate.

You have the right to see your test results and to request a copy of the insurer's underwriting decision. If you believe a result is wrong — for example, if the lab made an error — you can ask for a retest at the insurer's expense. Some conditions, like slightly elevated cholesterol or borderline blood sugar, may not affect your rate at all if everything else on your application is solid.

How to prepare for your blood test

Most insurers ask you to fast for 8 to 12 hours before the test, meaning no food or drink except water. This gives accurate readings for glucose and cholesterol. Avoid strenuous exercise the day of the test, because it can temporarily raise certain markers. Take your regular medications unless the insurer tells you otherwise.

Be honest about your medical history and current medications when you fill out the application. The blood test will reveal if you've omitted something, and dishonesty on an application can be grounds for denial or claim rejection later. If you're concerned about a particular result, mention it to the phlebotomist or the insurance company — they may order a follow-up test or ask your doctor for additional information.

Frequently Asked Questions

Can I refuse the blood test?

Yes, but the insurer can deny your application or charge you a much higher rate if you do. Some insurers offer "no-exam" policies that don't require blood work, but these typically come with higher premiums or lower coverage limits. If you have concerns about the test, ask the insurer what specific results they need and whether a follow-up with your own doctor would satisfy their requirements.

Will my doctor see my life insurance blood test results?

Not unless you ask the insurer to send them. The test is ordered by the insurance company and the results go to the insurer first. You have the right to request a copy, and you can share it with your doctor if you want. Some people do this to get a second opinion on abnormal findings or to discuss treatment options.

How long do blood test results take?

Most results come back within one to two weeks. The insurer then reviews them along with your application and medical records. The entire underwriting process typically takes two to four weeks, though it can be faster if everything is straightforward or slower if the insurer needs additional information from your doctor.

What if I have a chronic condition like diabetes or high blood pressure?

You can still get life insurance. The blood test will show whether your condition is controlled or uncontrolled, and your premium will reflect that. If you're taking medication and your condition is stable, your rate will be higher than someone without the condition, but usually not prohibitively so. If your condition is uncontrolled or severe, your rate will be higher or you may be declined by some insurers.

Can I retake the blood test if I don't like my results?

You can request a retest if you believe the results are inaccurate, but the insurer doesn't have to grant it. If you think you had an unusually high reading because you were stressed, sick, or hadn't fasted properly, explain that to the insurer and ask for another test. Some will agree; others will use the first result. You can also apply with a different insurer, who will order their own test.
