Guidelines

Specialty Testing in Immunology

Ordering & Collection

Specimen Type: Whole Blood
Collection: 5 mL blood in LAVENDER TOP tube. If Clinician suspects Cryoprecipitate, contact Immunology lab 206 598-6149 for special handling instruction
Handling Instructions: Whole blood sample is labile, send to lab ASAP.

Note: Test must be performed within 24 hours of draw time. Fridays: blood must be received by 1pm. Call Immunology Lab at 206-598-6149. If sample is delayed in getting to the lab, request can be changed to a plasma viscosity (PLVISG).

Whole blood must be centrifuged and plasma aliquoted if order is changed.
Quantity: requested: entire specimen
minimum: 0.5 mL whole blood

Processing

Processing: Refrigerate whole blood or plasma if the order is changed.
