These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 30.0 – 200 mg/dL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your Haptoglobin result may mean
Can reflect inflammation or infection (haptoglobin is also an acute-phase reactant).
Often reflects hemolytic anemia (red cell destruction).
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
