Platelet Function Tests
(Platelet aggregation study & Flowcytometry)
A platelet aggregation test checks how well your platelets clump together to form blood clots. Platelets are a type of blood cell. They help form blood clots by sticking together. A clot is what stops the bleeding when you have a wound. Without platelets, you could bleed to death.
Platelet aggregation study is GOLD STANDARD technology & available at referral centre in India.
Qualitative platelet defect can be presented with normal platelet counts in majority of the cases.
In the anticoagulated whole blood is mixed with saline and a platelet agonist in a single-use cuvette with two pairs of electrodes. The increase in impedance between the electrodes as platelets aggregate onto them, is measured and visualized as a curve
Agonist required for aggregation study: Ristocetin, ADP, AA (Aracdonic acid), Epinephrine, Collage, and TRAP- 6
Why test required:
-
Excessive Bleeding
-
Excessive Bruising
-
Bleeding from the nose or gums
-
Excessive menstrual bleeding
-
Blood in the urine or stool

- Incorrect identity of the specimen
Storage & Transportation
- Hemostasis & Thrombosis assays are very sensitive for preanalytical variables, storage & transportation.
- Outstation sample for Hemostasis & Thrombosis required transportation in Dry ice only.
- Flowcytometry sample should be stored & transported at room temperature (10 – 24 C).
- MRD assay required fresh & first pool sample.
- Outside laboratory collection for platelet function tests not acceptable except in special condition.
Note:
- Discussion with Laboratory personals required before sending special tests of specifically Coagulation & Thrombotic disorders.
- All special tests will be done on working day at Haempath Diagnostics except Sunday & holidays with prior appointment.
