Why Life Insurers Require Bloodwork
Bloodwork for life insurance gives underwriters a snapshot of your current health and long-term risk. The results help determine whether you qualify for coverage and which rate class you receive. Most applicants between ages 18 and 60 can expect a paramed exam that includes blood and urine samples, along with basic vitals. Insurers use these results to check for conditions such as high cholesterol, diabetes, liver issues, and indicators of nicotine or drug use. Understanding what is tested and how to prepare can reduce surprises and help you secure a better premium.

What the Blood Panel Typically Includes
The specific labs vary by carrier and the amount of coverage requested, but most paramedical exams include a standard set of tests. These are commonly drawn from a single venipuncture and often paired with a urine sample.
- Complete blood count (CBC) to check red and white blood cells
- Lipid panel including total cholesterol, LDL, HDL, and triglycerides
- Fasting or random blood glucose
- Hemoglobin A1c for longer-term glucose control
- Liver enzymes such as ALT and AST
- Kidney function markers including creatinine and BUN
- Thyroid-stimulating hormone (TSH)
- HIV and hepatitis screening in some cases
- Urinalysis for protein, glucose, and drug metabolites
How Results Affect Your Rate Class
Underwriters translate lab values into risk tiers. Slight elevations do not automatically disqualify you, but they can move you from a preferred tier to standard, which changes your monthly premium. For example, a total cholesterol above the carrier's threshold or an A1c in the prediabetes range may trigger a rate adjustment or a request for additional medical records. Some companies are more lenient with minor irregularities than others, which is why shopping across multiple carriers is a practical step.
Common Lab Thresholds That Influence Pricing
| Marker | Typical Preferred Range | Potential Impact of Elevation |
|---|---|---|
| Total Cholesterol | Under 200 mg/dL | Rate class may drop if consistently high |
| LDL Cholesterol | Under 130 mg/dL | May require additional documentation |
| Blood Glucose (fasting) | Under 100 mg/dL | Elevated levels can trigger diabetes screening |
| A1c | Under 5.7% | 5.7–6.4% may affect rating |
| ALT/AST | Within normal limits | Elevations may prompt liver follow-up |
How to Prepare for the Blood Draw
Proper preparation can stabilize your lab values and improve your chances of a favorable rate class. Most carriers and exam companies recommend similar steps in the days leading up to the appointment.
- Fast for 8 to 12 hours before the exam, drinking only water
- Avoid alcohol for at least 24 to 48 hours prior
- Skip strenuous exercise for 24 hours
- Drink plenty of water to make veins easier to access
- Avoid caffeine and nicotine for several hours before the draw
- Take prescription medications as directed unless told otherwise
- Get a good night of sleep the evening before
What Happens If Your Results Are Abnormal
An abnormal result does not mean denial. Underwriters often look at the pattern over time rather than a single reading. If a value is borderline, the examiner may request a re-draw or additional tests. In other cases, the carrier will ask for your attending physician's records to clarify the cause. Providing a complete medication list and recent doctor visits during the application process helps underwriters interpret results in context and avoid unnecessary delays.
Choosing a Carrier Based on Bloodwork Sensitivity
Different insurers weigh lab results differently. Some are stricter on cholesterol, while others focus more on glucose or liver markers. Working with an independent broker who knows each company's underwriting guidelines lets you target the carriers most likely to offer favorable rates based on your specific lab profile. This step matters most when your results sit near a threshold or when you have a manageable condition that is well controlled.
