Haptoglobin levels: what's normal, high and low
A protein that binds free hemoglobin from broken-down red cells. Drops when red cells are being destroyed faster than normal.

The short answer
Haptoglobin is measured with a standard blood draw; no fasting is needed. A typical reference range is 30.0 – 200 mg/dL. At TestWell it's $101.99 all-in as Haptoglobin, results in 2–4 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

What a high Haptoglobin means: causes, symptoms, next steps →Often reflects hemolytic anemia (red cell destruction).
What a low Haptoglobin means: causes, symptoms, next steps →Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.

Frequently asked
Can reflect inflammation or infection (haptoglobin is also an acute-phase reactant). A single result above the reference range is a prompt to look closer with a clinician — often a repeat test and related markers — not a diagnosis on its own.
