While you haven't mentioned, I assume you are taking a life insurance policy rather than a health insurance policy. Elevated lipid profile indicates certain deviation in your body, the exact nature of the same can only be confirmed by your doctor taking into consideration other factors. In so far as the implication on the policy premiums are concerned, they are a direct correlation to the risk that your physical condition represents. In case of any deviation, the risk of mortality is increased and as a result the insurance company wants to charge a higher premium in relation to the higher risk it is expected to underwrite now, which incidentally is a normal industry practice. Suggest you repeat the tests (at your cost) and consult your doctor. In case the reports are fine you could go back to this insurance company or prospect with another insurance company.
