Test ID: FCAH1
CAH Pediatric Profile 1, 21-OH Deficiency Screen (Androstene- dione, Cortisol, DHEA, 17-OH-Progesterone, Testosterone)
Specimen Type 
Describes the specimen type needed for testing
Serum
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Draw blood in a plain, red-top tube(s) or serum gel tube(s). Separate
within one hour of draw and send 2 mL of serum frozen in plastic vial
on dry ice. Specimens drawn in serum gel tube(s) must be poured off
into a plastic screw cap vial before freezing.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
1 mL
NOTE: Minimum volume does not allow for repeat analysis
