Specimen Info
Only 1 specimen type required, unless otherwise specified
Volume: 1.0 mL
Temperature: Refrigerated
Tube Type: Plasma
Collection Info:
BOTH PLASMA AND SERUM ARE REQUIRED
Collection Instructions:
1. Tube must remain at 37 degrees C.
2. Centrifuge at 37 degrees C. (Do not use a refrigerated centrifuge. If absolutely necessary, ambient temperature is acceptable.) It is very important that the specimen remain at 37 degrees
C until after separation of plasma from red cells.
3. Place plasma into an appropriately labeled plastic vial.
Temperature: Refrigerated
Tube Type: Plasma
Collection Info:
BOTH PLASMA AND SERUM ARE REQUIRED
Collection Instructions:
1. Tube must remain at 37 degrees C.
2. Centrifuge at 37 degrees C. (Do not use a refrigerated centrifuge. If absolutely necessary, ambient temperature is acceptable.) It is very important that the specimen remain at 37 degrees
C until after separation of plasma from red cells.
3. Place plasma into an appropriately labeled plastic vial.
Volume: 5.0 mL
Temperature: Refrigerated
Tube Type: Serum
Collection Info:
BOTH PLASMA AND SERUM ARE REQUIRED
Collection Container/Tube: Red top (serum gel/SST are not acceptable)
Collection Instructions:
1. Tube must remain at 37 degrees C.
2. Allow blood to clot at 37 degrees C.
3. Centrifuge at 37 degrees C. (Do not use a refrigerated centrifuge. If absolutely necessary, ambient temperature is acceptable.) It is very important that the specimen remain at 37 degrees
C until after separation of serum from red cells.
4. Place serum into an appropriately labeled plastic vial.
Additional Information: Analysis cannot be performed with less than 3 mL of serum. Smaller volumes are insufficient to detect clinically important trace (mixed) cryoglobulins. Less than 3 mL will require draw of a new specimen.

Clinical Utilities
Evaluating patients with vasculitis, glomerulonephritis, and lymphoproliferative diseases
Evaluating patients with macroglobulinemia or myeloma in whom symptoms occur with cold exposure
This test is not useful for general screening of a population without a clinical suspicion of cryoglobulinemia.

Reference Range
CRYOGLOBULIN
Negative (positives reported as percent)
If positive after 1 or 7 d, immunotyping of the
cryoprecipitate is performed.

Negative (reported as positive or negative)
Quantitation and immunotyping will not be
performed on positive cryofibrinogen.
Negative (positives reported as percent)
If positive after 1 or 7 d, immunotyping of the
cryoprecipitate is performed.
CRYOFIBRINOGEN
Negative (reported as positive or negative)
Quantitation and immunotyping will not be
