Specimen Requirements

Patient Preparation:

An 8-12 hour fast is not required, but is recommended. Indicate patient's fasting status on order request form.

Container Type:

Optimal: Gold or Mint*

*For STAT requests

Acceptable: Red or Green

Optimal Collection Volume: 

4.5 mL; full tube

Specimen Minimum Volume:
  • Adults: 1 mL whole blood
  • Neonates: 1 microtainer (400-600 uL) and 1 capillary gas tube
Collection Instructions:

Gently invert sample 5-6 times after collection.

Specimen Transport:

Refrigerate

Processing Instructions: 

1. If serum, allow the sample to clot for 30 minutes.

2. Centrifuge specimen within 2 hours of collection.

3. After centrifugation, specimen tubes without a gel barrier should have the serum or plasma aliquoted to a false bottom container.

4. Keep serum/plasma refrigerated until testing can be performed.
