What is antiplatelet antibody test?

This blood test shows if you have antibodies against platelets in your blood. Platelets are a part of the blood that helps the blood clot. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand.

What is a platelet antibody profile?

Platelet antibodies may be directed to a number of antigenic “targets” carried on platelet cytoplasmic membranes. 1-6. This platelet antibody profile is designed to detect antibodies to HLA class I and platelet glycoprotein IV (CD36) antigens, and to polymorphic epitopes on the platelet GPs IIb/IIIa, Ib/IX, and Ia/IIa.

What Is A Hit panel?

A test for heparin-induced thrombocytopenia (HIT) antibody, also called heparin-PF4 antibody, is performed to detect antibodies that develop in some people who have been treated with heparin.

What is ITP test?

Diagnostic Procedures for ITP Includes a special blood test called an “anti-platelet antibody test.” Careful review of medications. Bone marrow aspiration: This test examines the platelet production and can rule out any abnormal cells the marrow may be producing that could lower platelet counts.

Do you have to fast for a platelet blood test?

Most people don’t need to do anything to prepare for a platelet count. In some cases, your healthcare provider may want you to fast (not eat or drink) before the test. Be sure to ask your provider if there are any instructions you should follow or medications to avoid before your blood test.

What is the most common platelet antibody?

Platelet-reactive HLA antibodies were the most common antibodies.

How do you confirm hits?

Diagnosis of HIT is based on clinical assessment and laboratory results. Primary laboratory tests for HIT include immunologic assays, such as an enzyme-linked immunosorbent assay (ELISA), and functional, platelet-activation assays, such as the serotonin release assay (SRA).

What is HIT positive mean?

In the presence of low (therapeutic) heparin concentrations, HIT-positive sera result in platelet activation and platelet granule release. The platelet granules contain serotonin; thus, serotonin serves as a surrogate marker for platelet activation.

How do I monitor my ITP?

To diagnose immune thrombocytopenia, your doctor will try to exclude other possible causes of bleeding and a low platelet count, such as an underlying illness or medications you or your child may be taking. Blood tests can check the levels of platelets.
