 Specimen Collection
Source:

Site:

Container:Red/Yellow Rim 4mL SST

Micro. Container:


Collection Instructions:

Immediately after collecting blood in a tube, gently invert the tube at least 5-8 times. This allows exposure of entire blood specimen to the clot activator that coats the tube’s walls and minimizes instrumentation problems caused by delayed clotting.

Delivery Instructions:Send specimen to 2C324 or Tube Station 321
Specimen Type: Blood
