Cryoglobulin Identification
General Information
- Lab Name
- Cryoglobulin ID
- Lab Code
- CRYIDG
- Epic Name
- Cryoglobulin ID
- Description
If Cryoglobulin is present in sufficient quantities to perform an ID, a Cryoglobulin ID will be ordered with additional charge.
This assay characterizes the immunoglobulins present in the cryoglobulin cryoprecitate. The 3 types of cryoglobulins are differentiated by the types of immunoglobulins present in the complexes (type 1 = monoclonal, type 2 = mixed monoclonal + polyclonal, and type 3 = polyclonal), and are associated with different clinical conditions.

- Blood
- Collection
-
15 mL blood in RED TOP tube.
Specimen must be maintained at 37°C after collection.
- Handling Instructions
Keep sample warm and transport to lab IMMEDIATELY. Suggest transporting specimen maintained at 37°C, possibly under your arm with specimen tube securely enclosed in a specimen transport bag. Specimen will be rejected if clotted. Not to be drawn on blood draw rounds.

Processing
- Receiving Instructions
UW-MT Instructions:
Specimen MUST be kept at 37°C until received by COAG Lab. COAG: Put "unclotted" specimen in 37°C waterbath to clot for 1-2 hours to prevent CRYOGLOBULINS from being trapped in clot. After clotting is complete, spin & aliquot serum while serum is still warm. Return sample to the refrigerator in SPS. Do Not Freeze.
HMC Instructions:
Specimen MUST be kept at 37°C until received by SPS. SPS will put "unclotted" specimen in 37°C waterbath to clot for 1-2 hours to prevent CRYOGLOBULINS from being trapped in clot. After clotting is complete, spin & aliquot serum while serum is still warm. Refrigerate serum. Do not freeze.
Outside Lab Instructions:
Specimen MUST be kept at 37°C until recieved in the lab. The lab will put "unclotted" specimen in 37°C waterbath to clot for 1-2 hours to prevent CRYOGLOBULINS from being trapped in clot. If a waterbath is not available, a 37°C heat block is acceptable. After clotting is complete, spin & aliquot serum while serum is still warm. Refrigerate serum. Do Not Freeze.
