Test Code CORT 
Methodology Electrochemiluminescence Immunoassay (ECLIA) 
Description Useful as an indicator of adrenocortical function.

No sample should be collected on patients receiving therapy with high biotin doses (i.e. biotin therapy for Multiple Sclerosis or oncology patients; skin, hair and nail supplements, or multivitamins containing > 5 mg/day) until at least 12 hours after the last biotin administration. If unsure, or if the clinical picture does not fit the results please contact the laboratory . We have methods to check for biotin interference as well as for any other interferences and for the accuracy of the results.

Biotin interference would falsely increase the result of this assay. 

Specimen Draw blood in either a plain, red-top tube or serum gel tube. Spin down and send 1.0 mL (0.5 mL minimum) of serum refrigerated.

NOTE: Include date and time of collection on request form.
