Haptoglobin

This is a blood test used to detect destruction of the red blood cells within the blood vessels. This test finds whether the haptoglobins which are produced by the liver are at a low level. The haptoglobins are a protein which bind to red blood cells. The haptoglobins are decreased in patients with different types of liver diseases and can be increased in many inflammation processes, severe infection, tissue destruction, heart attack, burns, and some cancers.

PREPARATION FOR TEST

No preparation or fasting is necessary.

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.

MEANING OF TEST
