Final answer:
A cryoglobulin specimen should be kept at body temperature, 37 degrees Celsius, during transport to the lab to prevent cryoglobulins from precipitating or clumping, which can impact test results.
Step-by-step explanation:
You're transporting a cryoglobulin specimen to the lab, and you should keep the specimen at 37 degrees Celsius (98.6 degrees Fahrenheit). Cryoglobulins are proteins typically found in the blood that precipitate or clump together at cold temperatures. If the temperature is too low, they can precipitate out of the serum or plasma, which could affect the test results or lead to an inaccurate diagnosis. Therefore, it's essential to maintain the specimen at body temperature, avoiding any temperature-induced changes to the sample's properties.
