Thermos filled with sand kept in a 37C incubator seems to be a good solution, although not sure how you would calculate the measurement uncertainty of this practice.

Subject: Cyroglobulin Evaluation

Best practice recommendation for cyroglobulin evaluation is to collect blood directly into a warmed container at 37C and transport to the laboratory at or > 37C (Ann Clin Biochem 2010; 47: 8-16). We are having trouble sourcing a container that is suitable for pre-warming and transporting collection tubes for this purpose.

I would appreciate hearing about what devices other labs use for cyroglobulin evaluation and where to get them.

Many thanks

David Parry
