Methodology

TEG 6s Hemostasis analyzer using the TEG Citrated Multichannel Cartridge.

The system provides semi-quantitative indications of the hemostatic state of a whole blood sample.

Specimen Requirements

A plain, red-top  (for waste purposes) and 3.2% Sodium Citrate tube

 

Blood must be drawn in the following sequence using a 21-gauge needle. Under no circumstances should a smaller gauge needle be used. The use of a butterfly needle with tubing is specifically recommended if available, as it puts less pressure on the vein.

 

Specimen Type: Whole blood

 

Container/Tube: Plain, red-top tube 

 

Specimen Type: Sodium citrate whole blood

 

Container/Tube: 3.2% sodium citrate tube

 

All blood tubes must be filled completely (until vacuum is exhausted). A short draw is not an acceptable sample. 

 

Collection Instructions: Mix gently and deliver STAT. Do not centrifuge. Tubes must be full.   Mix gently but thoroughly.  

Specimens must be analyzed within 2 hours of draw.
