36562: Cryoglobulin (% Cryocrit), Serum Print View
Cryoglobulin, QL (UOM)      
% Cryocrit (UOM%)     % 

PRIMARY
1 Serum 3 (2) mL   Room Temperature - 72 Hour(s)  
ALTERNATE

Patient Preparation: Overnight fasting is required.

Collect 6 mL of fasting whole blood specimen in a red-top tube
(no gel). 3 mL serum required: 2 mL minimum.
Avoid hemolysis. Allow serum sample to clot for one (1) hour in
a 37 degree C Water bath, Oven, Incubator, or Heat Block. If
none of these are available, adjust tap water in a container to
37 degrees C. Place collection tube into container and monitor
temperature throughout the clotting process. Add more 37 degrees
C water to container as needed to maintain temperature
throughout entire process.
After clotting, centrifuge the specimen for 10 minutes at 3000
rpm utilizing ONE of the 3 options below:
1) In a 37 degree C centrifuge; or
2) In a bench-top centrifuge placed in a warm room at 37 degree
C; or
3) In a bench-top centrifuge that you have prewarmed by
running it for 10 minutes at 2000 rpm prior to centrifuging the
clotted specimen tube.
After centrifuging, decant serum into a screw-capped vial.
NOTE: If the sample is NOT kept at 37 degrees C during all
processing steps, the cryoprecipitate if present can precipitate
out of solution and be lost in the clot or during the
centrifugation process and result in a false negative result.
Transport screw-capped vial at room temperature.
DO NOT REFRIGERATE OR FREEZE.

Note: No tests can be added or poured off this tube; cryocrit and
cyroglobulin evaluation only.
