# What does a high Haptoglobin mean?

> 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?

1. Acute or chronic inflammation, infection
2. Tissue injury, surgery, heart attack
3. Corticosteroids, some androgens
4. Nephrotic syndrome, cancers
5. 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

## 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.
