Specimen Requirements

Submit only 1 of the following specimens:

 

Preferred:

Plasma

Draw blood in a green-top (lithium heparin) tube. For pediatric specimens, draw blood in a green-top (lithium heparin) MICROTAINER®. Label specimen with patient’s name (first and last), date of birth, date and time of draw and the phlebotomist’s initials. Spin down and send 2 mL of lithium heparin plasma refrigerated. Avoid exposure of specimen to atmosphere. Do not transfer or open tube. 

 

Alternate:

Serum

Draw blood in a gold top (serum separater) gel tube. Label specimen with patient’s name (first and last), date of birth, date and time of draw and the phlebotomist’s initials. Spin down and send 2 mL of serum refrigerated. Avoid exposure of specimen to atmosphere. Do not transfer or open tube.

 

Note:  Glucose will drop 5.0 mg/dL to 10 mg/dL per hour in an unseparated, ambient serum gel tube.

 

Hemolyzed or lipemic specimens are not acceptable.
