Elevated Tryptase Levels | Mast Cell Disorders | Praana Center

At Praana Center for Asthma and Allergy, we help patients understand what an elevated tryptase level means—and just as importantly, what it does not mean.

What Is a Tryptase Test?

A serum tryptase test measures activity from mast cells, immune cells that play a key role in allergic reactions, asthma, hives, and anaphylaxis.

Most laboratories consider tryptase levels below ~11 ng/mL to be normal. Some patients are found to have mildly elevated levels, often between 12–20 ng/mL.

What Does an Elevated Tryptase Mean?

A mildly elevated tryptase does not automatically indicate a serious disease.

The most common cause is hereditary alpha-tryptasemia (HαT), a genetic trait that results in higher baseline tryptase levels and more sensitive mast cells. This condition is far more common than systemic mastocytosis and is not cancer.

In some cases, elevated tryptase may also reflect mast cell activation, especially if the test was drawn during or shortly after an allergic reaction.

Possible Symptoms

Some people with elevated tryptase have no symptoms at all. Others may experience:

  • Chronic hives or itching

  • Flushing or warmth of the skin

  • Gastrointestinal symptoms such as reflux, abdominal pain, or diarrhea

  • Lightheadedness or fatigue

  • Medication, food, or insect sting reactions

  • Strong or prolonged allergic responses

How We Evaluate Elevated Tryptase

At Praana Center for Asthma and Allergy, we use an evidence-based, stepwise approach:

  • Confirming whether the level represents a true baseline elevation

  • Reviewing symptoms suggestive of mast cell activation

  • Considering genetic testing for hereditary alpha-tryptasemia when appropriate

  • Reserving advanced testing for patients with specific clinical red flags

Our goal is to provide clarity while avoiding unnecessary invasive testing.

Personalized Treatment & Management

Management focuses on symptom control and prevention. Depending on your symptoms, this may include:

  • Daily or as-needed antihistamines

  • Medications to reduce mast cell mediator effects

  • Trigger identification and avoidance strategies

  • Emergency preparedness, including epinephrine when indicated

Most patients experience significant improvement with the right plan in place.

A mildly elevated tryptase level is often a benign finding. Many patients live full, healthy lives with simple, proactive management.

Our role is to help you understand your results, reduce uncertainty, and create a plan that keeps you safe and comfortable.
