VHA | Assay | Reagents | Clinical Significance |
---|---|---|---|
TEG/PM® | Kaolin TEG MA | Kaolin | MACK parameter is a proxy for the maximum potential function of the platelets. Thrombin overrides inhibition via anti-platelet agents, thus kaolin-activated TEG® samples will not exhibit their effects. |
Activator TEG MA | Heparin, reptilase, FXIIIa | MAActivator represents the isolated fibrin contribution to clot strength. Performed alongside K-TEG®. |
|
TEG MAAA | Heparin, reptilase, FXIIIa, AA | Measures AA contribution of platelet activity to clot strength. Performed alongside K-TEG®. |
|
TEG MAADP | Heparin, reptilase, FXIIIa, ADP | Measures the ADP/GPIIb/IIIa pathways’ contribution of platelet activity to clot strength. Performed alongside K-TEG®. |
|
ROTEM Platelet Analysis® | ARATEM | AA | Determines GPIIb/IIIa and COX-1 receptor inhibition. |
ADPTEM | ADP | Determines GPIIb/IIIa and ADP (P2Y12) receptor inhibition. | |
TRAPTEM | TRAP-6 | Determines GPIIb/IIIa and thrombin (PAR-1) receptor inhibition. |
