Specimen Requirements

Special Note: Spin down specimen within two hours of draw.  Glucose decreases 5-8% every hour of uncentrifugation.

Particulate matter (for example, fibrin) in sufficient quantity may coat the spreading layer and limit diffusion of oxygen, causing a negative interference. To minimize particulate matter, do not centrifuge specimens until clotting is complete.
