QUALITATIVE DETERMINATION OF PLATELET

• Electronic Particle Counter

• Examination of stained blood film

• Thromboxanes

Available techniques can include complement fixation methods, lysis of chromium 51–labeled platelets, assays of platelet-bound immunoglobulins, and competitive inhibition assays.

• BLEEDING TIME WITH AND WITHOUT ASPIRIN

• CLOT REACTION

• PLATELET AGGREGATION

• ANTIPLATELET ANTIBODY ASSAY

Agents such as ADP, collagen, epinephrine, snake venom, thrombin, and ristocetin can be used to aggregate platelets.

• BLEEDING TIME WITH AND WITHOUT ASPIRIN

• CLOT REACTION

• PLATELET AGGREGATION

• ANTIPLATELET ANTIBODY ASSAY

The principle of the test is that platelet-rich plasma is treated with a known aggregating agent. If aggregated, cloudiness or turbidity can be measured using a spectrophotometer

• BLEEDING TIME WITH AND WITHOUT ASPIRIN

• CLOT REACTION

• PLATELET AGGREGATION

• ANTIPLATELET ANTIBODY ASSAY

In vivo measurement of platelet adhesion and aggregation on locally injured vascular subendothelium.

• BLEEDING TIME WITH AND WITHOUT ASPIRIN

• CLOT REACTION

• PLATELET AGGREGATION

• ANTIPLATELET ANTIBODY ASSAY

Provides an estimate of the integrity of the platelet plug and thereby measures the interaction between the capillaries and platelets
