Haptoglobin
A protein that disappears from blood when red cells break down, making it a key marker of hemolysis.
Consider this test if:
- Unexplained anemia, fatigue, jaundice, or dark urine that points toward red cell breakdown
- Working up a suspected hemolytic anemia alongside LDH, reticulocytes, and bilirubin
- Monitoring a known hemolytic condition or response to treatment
- Investigating anemia that has not responded to iron, B12, or folate
- HSA/FSA eligible
- Typical results in 1-2 days · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
Avoid strenuous exercise before the draw, and a clean venipuncture matters because hemolysis from a traumatic draw can distort the result. No fasting is required. Because haptoglobin rises with inflammation and infection, an acute illness can mask an otherwise low level.

What this test is for
Haptoglobin is a protein that binds free hemoglobin released when red blood cells break apart, then carries it to the liver and spleen for clearance. Low or absent haptoglobin is one of the most useful signals of intravascular hemolysis, where red cells are destroyed faster than the body can replace them, and it is also seen in megaloblastic anemias, liver disease, and tissue hemorrhage. High haptoglobin behaves as an acute phase reactant, rising with inflammation, infection, collagen vascular disease, and advanced malignancy. A small fraction of some populations have congenital ahaptoglobinemia (no detectable haptoglobin), so an undetectable result is read against the clinical picture rather than assumed to be hemolysis. It is most informative when paired with other hemolysis markers such as LDH, reticulocyte count, and bilirubin.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
