Part of our guide: Impaired Risk Life Insurance Underwriting by Condition →
The NT-proBNP blood test is now a routine part of many insurance lab panels, especially for older applicants. An abnormal result can derail a case, but a favorable one can help.
Key takeaways
- NT-proBNP is a marker of cardiovascular risk and long-term mortality, released when the heart is under strain.
- Some carriers decline or require a cardiac work-up when the result is abnormal.
- One carrier uses a normal result as a credit for applicants 70 and older, lifting a 75-year-old with a past TIA from mild substandard to Standard.
A normal NT-proBNP turned a mild substandard offer into Standard for a 75-year-old with a prior mini-stroke.
What the test measures
NT-proBNP is released by the heart when it’s working too hard: when it isn’t pumping enough blood to meet the body’s needs, is short of oxygen, or the main heart muscle is enlarged. It’s a marker for overall cardiovascular risk and long-term mortality in people with heart disease.
When the result is abnormal
An abnormal result on an insurance lab panel can lead some carriers to decline automatically, or to require an additional cardiac work-up at the applicant’s expense before reconsidering.
When the result is favorable
One of our A-rated carriers uses a favorable result as an underwriting credit for applicants age 70 and older.
- Male, age 75, non-smoker, seeking $500,000 of UL
- History of a TIA (mini-stroke) three years ago, followed closely by his doctor
- Insurance labs showed an NT-proBNP of 55 (normal)
Normally a mild substandard rating; with the credit, Standard.
Why it matters for older clients
For senior applicants, good lab results can offset history that would otherwise be rated. Ask our Underwriting Team which carriers credit favorable labs before you choose where to submit. For another senior cardiac case, see Standard at 72 with coronary artery disease.
Frequently asked questions
What is NT-proBNP on a life insurance blood test?
A marker the heart releases when it’s under strain. Insurers use it to assess cardiovascular risk, especially for older applicants.
What happens if NT-proBNP is high on an insurance exam?
Some carriers decline or ask for further cardiac testing. Others may still consider the case, so it’s worth shopping.
Can a good NT-proBNP improve a life insurance offer?
Yes. One carrier uses a normal result as a credit for applicants 70 and older, which can improve the rate class.
