Description

Patients on anticoagulant therapy will benefit from the AlphaLab™ Vacuum Tube, but it can also be used for routine coagulation testing. In coagulation studies, sodium citrate is utilized as an anticoagulant. It acts as an anticoagulant by creating compounds with metal ions like calcium, preventing the coagulation cascade from taking place. Trisodium citrate anticoagulation is reversible.

AlphaLab Vacuum Tube contains buffered citrate in accordance with recommendations: 0.105 M or 0.109 M of buffered trisodium citrate solution, equivalent to 3.2% trisodium citrate.
The blood to additive ratio is 9:1.
Conditions for centrifugation: Different plasma specifications can be obtained from citrated blood for coagulation analyses.
Platelet-rich plasma: 150-200 g at 18-25°C for 5 minutes.
Platelet-poor plasma: 2000-2500 g at 18-25°C for 10-15 minutes.
Platelet-free plasma: >3000 g at 18-25°C for 15-30 minutes.
Glass Tubes: Platelet-rich.
Plasma: 150-200 g at 18-25°C for 5 minutes.;
Platelet-poor plasma: 2000-2500 g at 18-25°C for 10-15 minutes.
Platelet-free plasma: >3000 g at 18-25°C for 15-30 minutes.
