Heparin-Induced Thrombocytopenia (HIT), Antibodies2548
The test is aimed at detecting specific antibodies to the "heparin-platelet factor 4" complex, which is the basis for diagnosing type II heparin-induced thrombocytopenia (HIT). This is a primary screening test that helps quickly confirm or exclude the diagnosis in patients receiving heparin treatment who experience a sharp drop in platelet count or new thromboses.
The test has very high sensitivity, allowing for almost 100% exclusion of heparin-induced thrombocytopenia diagnosis with a negative result. Timely diagnosis helps prevent complications related to thrombosis and adjust treatment for patients receiving heparin.
- Suspected type II heparin-induced thrombocytopenia (HIT).
- Sharp decrease in platelet count during heparin treatment.
- Development of new thromboses during heparin use.
Enzyme-linked immunosorbent assay (ELISA) is a highly sensitive laboratory method that allows the detection of IgG antibodies to the heparin-platelet factor 4 (PF4) complex.
Please note that the research method and reference values may vary depending on the equipment and test systems used.
- Blood collection in the morning on an empty stomach or 4 hours after eating.
- Allowed to drink plain still water.
- Do not smoke 30 minutes before the test.
- For children under 1 year – no food 30-40 minutes before the test; for children 1-5 years – 2-3 hours fasting.
