Additional Specimen Collection Information

Collect blood in a lithium heparin, green-top or red-top tube
from a fasting patient. (12 hour fast is recommended.) PST and SST
(gel tubes) are acceptable. Serum or plasma should be separated
from contact with the cells within 2 hours of collection. Specimens
not centrifuged within 4 hours of collection may be rejected.
Refrigerate the specimen if unable to assay within 8 hours of
collection. Hemolyzed specimens are not acceptable. Samples with
>3+ lipemia must be cleared prior to analysis.
