Additional Specimen Collection Information

Collect blood in a lithium heparin, green-top or red-top
tube from a fasting patient. (A 12 hour fast is
recommended.) PST and SST (gel tubes) are acceptable. Serum or
plasma should be separated from contact with cell within 2 hours of
collection. Refrigerate the specimen if unable to assay within 8
hours of collection. Hemolyzed specimens are not acceptable.Lipemic
specimens must be cleared prior to analysis.
