All of the Following Specimens are Required

Specimens Containers Min Volume
Serum Leakproof Tube 0.5 mL

Collection Protocol

Collect blood in appropriate vacutainer tube. Allow blood to clot at room temperature for 30 to 60 minutes prior to separation. Centrifuge to separate serum from the clot. Transfer (pipette) serum into plain leakproof tube.

Avoid hemolysis and lipemia. Fasting is only necessary to avoid lipemia. If the sample is not lipemic, non-fasting is okay. If the sample is still lipemic after fasting, indicate on the submittal form and submit.

Unspun samples will not be accepted. Do not send whole blood. ONLY serum samples will be accepted. Do not ship samples in serum separator tubes.

Shipping Requirements

Refrigerate (no longer than overnight) or freeze sample until shipment. Ship on ice via overnight or second day courier.

We recommend shipping with an ice pack using the MSU VDL Insulated
Mailer with UPS (99220 - Single, 99221 - 3 pack or 99222 - 6 pack).

Additional Information

A baseline cortisol concentration is used in conjunction with a dexamethasone suppression test or ACTH stimulation test. A baseline cortisol concentration is not useful in diagnosis of hyperadrenocorticism, but may be helpful in ruling out hypoadrenocorticism.
