ADAMTS13 Activity Test

The ADAMTS13 Activity Test measures the function of the ADAMTS13 enzyme, important for regulating blood clotting. It helps diagnose conditions like Thrombotic Thrombocytopenic Purpura (TTP).

General information only: This page is not a diagnosis or personal medical advice. A qualified clinician should decide whether testing is appropriate and interpret results in context.

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Unexplained low platelet count (thrombocytopenia)
  • ✓Signs of microangiopathic hemolytic anemia
  • ✓Suspected Thrombotic Thrombocytopenic Purpura (TTP)
  • ✓Family history of coagulation disorders
  • ✓Recurrent thrombosis
  • ✓Monitoring known ADAMTS13 deficiency

In plain language

What this test helps you understand

This test helps diagnose conditions where the ADAMTS13 enzyme is deficient or dysfunctional, such as Thrombotic Thrombocytopenic Purpura (TTP). It aids in differentiating TTP from other conditions with similar symptoms.
The ADAMTS13 Activity Test is a specialized diagnostic tool used to assess the activity of the ADAMTS13 enzyme in the blood. This enzyme plays a crucial role in the regulation of blood clotting by cleaving von Willebrand factor (vWF), which is essential for proper platelet function. Understanding the activity of ADAMTS13 is vital in diagnosing and managing various coagulation disorders, including Thrombotic Thrombocytopenic Purpura (TTP).

This test measures the functional activity of the ADAMTS13 enzyme. A deficiency or dysfunction of this enzyme can lead to excessive clot formation, resulting in serious health complications. By evaluating the activity levels of ADAMTS13, healthcare providers can make informed decisions regarding patient management and treatment.

Individuals who may need the ADAMTS13 Activity Test include:

* Patients exhibiting symptoms of unexplained thrombocytopenia (low platelet count). * Individuals with signs of microangiopathic hemolytic anemia. * Patients with a family history of coagulation disorders. * Those who have experienced recurrent episodes of thrombosis.

If you have any of these symptoms or risk factors, consult your healthcare provider about the necessity of this test.

Taking the ADAMTS13 Activity Test offers several benefits:

* Accurate diagnosis of coagulation disorders, particularly TTP. * Guidance for appropriate treatment options. * Monitoring of patients with known coagulation issues. * Peace of mind for patients and their families.

Results from the ADAMTS13 Activity Test will indicate the level of enzyme activity in your blood. Normal results suggest adequate enzyme function, while low levels may indicate a deficiency. Your healthcare provider will interpret your results in the context of your symptoms and medical history, guiding further management.

Questions people ask

Frequently asked questions

ADAMTS13 is an enzyme in the blood that helps regulate blood clotting by breaking down large proteins called von Willebrand factor.
A low level indicates that the enzyme is not functioning properly, which can lead to excessive blood clot formation and conditions like TTP. Your doctor will interpret this in context.
Overnight fasting is preferred. Ensure you have the necessary Coagulation Requisition Form (Form 15) completed.
The sample must be collected in a specific tube (Blue Top) and transported to the lab promptly, ideally within 4 hours, or processed correctly for freezing.
