What is APST Full Form in Medical?

The APST full form in medical term is Autologous Plasma Skin Test. This is a diagnostic test that is used in dermatology and also in allergy medicine. It is used to identify conditions such as hives or urticaria. In this test, a small amount of the plasma of the patient will be injected into the skin. The doctors will then observe the skin for allergic reactions. This test is designed to detect the immune factors and auto antibodies in the plasma of the patient.

Significance of APST in medicine:

The autologous plasma skin test has important clinical applications, particularly in the diagnosis of chronic spontaneous urticaria and other autoimmune-related skin disorders. The test works by injecting the patient’s plasma intradermally and observing the response to determine the presence of autoantibodies or immune mediators that cause inflammatory skin reactions. A positive test suggests that the disorder has an autoimmune origin, which leads practitioners to targeted therapy such as antihistamines, immunosuppressants, or biologics like omalizumab.

What does positive APST test mean?

A positive autologous plasma skin test indicates the presence of immune factors, such as inflammatory mediators and auto-antibodies in the blood of the patient. A positive test supports the diagnosis of auto-immune chronic urticaria, rather than non-immune cases. A positive result may also indicate prolonged hives or urticaria in the skin.
