What Haptoglobin measures
Haptoglobin binds hemoglobin released from broken red cells. It is used when red cells may be breaking down faster than usual.
If your Haptoglobin is low
Haptoglobin below the range is commonly associated with red cells breaking down in the circulation, because the protein is used up binding released hemoglobin; some people inherit low levels.
Commonly associated with
- Red cells breaking down faster than usual
- Liver function
- Inherited low haptoglobin
If your Haptoglobin is high
Haptoglobin above the range is commonly associated with inflammation or infection, since it rises as part of the acute-phase response.
Commonly associated with
- Inflammation
- Infection
- Corticosteroid medication
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 30 – 200 mg/dL |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your haptoglobin is within the range printed by your lab.
