What does a high Haptoglobin mean?

Short answer

Haptoglobin is an acute-phase protein, so it rises with inflammation, infection, tissue injury, some cancers, nephrotic syndrome and corticosteroid use. A high haptoglobin has little meaning on its own; its main importance is that inflammation can mask hemolysis by holding haptoglobin in the normal range when it should be low.

What is the normal range for Haptoglobin?

age 18+: 30.0 – 200 mg/dL

Can reflect inflammation or infection (haptoglobin is also an acute-phase reactant).

What are the common causes of high Haptoglobin?

Acute or chronic inflammation, infection
Tissue injury, surgery, heart attack
Corticosteroids, some androgens
Nephrotic syndrome, cancers
Obesity, smoking (mild)

What symptoms go with high Haptoglobin?

None from haptoglobin itself

What do clinicians usually check next?

CRP or ESR to gauge inflammation
If hemolysis was the question, rely on reticulocytes, LDH and bilirubin — haptoglobin is unreliable during inflammation

Follow-up tests available at TestWell: Body Inflammation Test (ESR) ($18.99), C-Reactive Protein (CRP) ($26.99), LDH (Lactate Dehydrogenase) ($19.99), Sed Rate (ESR) ($24.99).

How do you recheck Haptoglobin?

Prices are cash-pay; every order adds one $6 lab processing fee. Physician authorization is included; no insurance or referral needed.

Common questions

Is high haptoglobin a problem?

Not by itself — it is a nonspecific inflammation marker. Its relevance is that inflammation can hide hemolysis on this test.
