Tryptase analysis: what is it, who needs it and what are the indications for its conduct?
Tryptase is one of the key indicators of allergic and systemic reactions of the body. Determining its level in the blood helps to detect serious immunological disorders, diagnose anaphylaxis, assess the risk of allergic reactions, or confirm mastocytosis.
In the medical laboratory "Medilab Plus" tryptase is determined using enzyme immunoassay, which allows you to get an accurate result on the day of delivery. You can learn more about our services on the website Medilab Plus, where a complete list of analyses is presented.
And if you are interested in diagnosing tryptase levels, follow the link to the page Immunoallergy diagnostics: Tryptase — here you will find all the necessary information about research, preparation, and obtaining results.
What is tryptase and what is its role?
Tryptase is an enzyme found in the body's mast cells. It is released when they are activated, such as in an allergic reaction, anaphylaxis, or chronic mastocytosis.
| Source | Main function |
|---|---|
| Mast cells | Immune response, development of inflammatory reactions, participation in allergies |
High levels of tryptase often indicate an acute allergic condition or chronic mast cell pathology.
Indications for taking a tryptase test
Indications for taking a tryptase test- Suspected anaphylaxis
- Assessment of allergic reaction after acute manifestations
- Suspicion of systemic mastocytosis
- Unclear etiology of allergic symptoms
- Control after treatment of allergic diseases
- Preparation for allergen-specific immunotherapy or for the introduction of new drugs
When is analysis especially important?
| Symptom | Possible cause |
| Difficulty breathing, swelling | Anaphylaxis |
| Rash, itching | Allergy or hives |
| Systemic flushing, headache | Mastocytosis |
| High temperature for no reason | Systemic reaction |
How is the research going?
- Venous blood sampling
- Conducting ELISA (enzyme-linked immunosorbent assay)
- Result delivery during the working day
Reference values and their meanings
| Tryptase level, ng/ml | Interpretation |
| Up to 15 | Variant of the norm |
| 15–20 | Possible risk of allergic reactions |
| 20–200 | Probability of mastocytosis or acute anaphylaxis |
| >200 | Requires urgent further examination |
Examples of clinical situations
| Case | Tryptase level | Conclusion |
| Anaphylactic shock after an insect bite | 45 | Acute anaphylaxis |
| Persistent hives and headache | 60 | Possible mastocytosis |
| Preventive examination | 12 | Norm |
After insect bites, ticks and other allergens - when is it important to take a tryptase test?
Tryptase is a marker of mast cell activation that helps detect dangerous allergic reactions in time. It is especially important to determine the level of tryptase after bites or contact with potentially allergenic agents.
| Situation | Why is it important to take the test? | Who is recommended? |
|---|---|---|
| Bee, wasp, or hornet sting | May cause systemic allergic reaction or anaphylaxis | Adults and children who have symptoms after a bite |
| Tick bite | Risk of developing an allergy or reaction to tick toxins | For patients after an established bite |
| Bites from other insects (ants, midges) | Individual hypersensitivity, risk of edema or urticaria | For people prone to allergies |
| Unknown bites or rashes | For differential diagnosis of the cause of an allergic reaction | By referral from an allergist or family doctor |
| Allergic reactions after walks or contact with nature | To prevent the body from hyperreacting | Adults, children, patients at risk |
How to prepare for the analysis?
How to prepare for the analysis?- It is advisable to take the test on an empty stomach (after an 8-hour break from eating)
- Avoid stressful situations 24 hours before the test
- Avoid physical activity for 12 hours
Advantages of analysis in Medilab Plus
- Certified laboratory equipment
- Get results quickly
- Individual approach
- Possibility of online booking and consultation
Why shouldn't you delay?
The increase in tryptase levels lasts no more than a few hours after an acute reaction. A timely analysis allows the doctor to get a real picture of the patient's condition. Delay can lead to the loss of diagnostically important indicators.
Frequently asked questions from patients
| Question | Respond |
| Can I donate without symptoms? | Yes, for preventive examination |
| How much does the analysis cost? | Affordable price, details on the website |
| Is a doctor's referral required? | No, but it is advisable to consult before submitting. |
Tryptase testing is not just a test, but an important diagnostic tool that can help identify serious allergic and immune disorders. If you have allergic symptoms or have had an acute reaction, don't delay getting tested.
