Enter the hemoglobin and haptoglobin levels into the calculator to determine the H Factor. This calculator helps in assessing hemolysis in patients.

H Factor Formula

The following formula is used to calculate the H Factor.

H Factor = Hemoglobin / Haptoglobin

Variables:

  • Hemoglobin (g/L) is the concentration of hemoglobin in the blood.
  • Haptoglobin (g/L) is the concentration of haptoglobin in the blood.

To calculate the H Factor, divide the hemoglobin concentration by the haptoglobin concentration.

What is the H Factor?

The H Factor is a calculated value used in medical diagnostics to assess the extent of hemolysis, which is the breakdown of red blood cells. It is determined by the ratio of hemoglobin to haptoglobin in the blood. A low H Factor can indicate increased hemolysis, as haptoglobin binds to free hemoglobin released during red blood cell destruction.

How to Calculate the H Factor?

The following steps outline how to calculate the H Factor.


  1. First, determine the hemoglobin concentration in the blood (g/L).
  2. Next, determine the haptoglobin concentration in the blood (g/L).
  3. Use the formula H Factor = Hemoglobin / Haptoglobin.
  4. Finally, calculate the H Factor.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Hemoglobin (g/L) = 150

Haptoglobin (g/L) = 1.0
