Life insurance blood work typically screens for key health indicators such as cholesterol levels, blood glucose, liver and kidney function, and markers of cardiovascular risk, providing insurers with a snapshot of an applicant's medical risk.

Core Blood Tests Used by Insurers
Most carriers order a standard panel that includes:
- Complete lipid profile (total cholesterol, LDL, HDL, triglycerides)
- Fasting glucose or HbA1c to assess diabetes risk
- Liver enzymes (ALT, AST) and bilirubin
- Kidney function (creatinine, BUN, eGFR)
- Complete blood count (CBC) for anemia or infection clues
Why These Markers Matter
Elevated LDL or low HDL signals higher chances of heart disease, which is a leading cause of death and a major factor in underwriting. High glucose or HbA1c indicates diabetes, a condition linked to multiple complications that raise mortality risk. Abnormal liver or kidney results can reveal chronic disease or substance use, both of which affect life expectancy.
Additional Tests That May Be Requested
Depending on age, medical history, or the amount of coverage sought, insurers might add:
- Thyroid panel (TSH, T4) to detect hypo‑ or hyperthyroidism
- Inflammatory markers such as CRP
- Hepatitis and HIV screens
- Genetic or hormone panels for specific high‑risk groups
How Results Influence Your Policy
Results are categorized into risk classes. Normal ranges usually qualify for standard rates, while borderline or elevated values can lead to preferred‑plus, standard‑plus, or substandard classifications, each with higher premiums. In some cases, insurers may request a medical exam or additional documentation before issuing a final decision.
Improving Your Blood Work Before Applying
Adopting a heart‑healthy diet, regular exercise, and managing existing conditions can bring lab values into healthier ranges. Many applicants retest after a few months of lifestyle changes to qualify for better rates.
