Test ID: FGNRH    
Gonadotropin Releasing Hormone (Gn-RH)

Specimen Type Describes the specimen type needed for testing

Varies

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.

Submit only 1 of the following specimens:

 

Serum

Draw blood in a plain, red-top  or serum-gel tube(s). Separate

immediately and send 3 mL of serum frozen in a plastic vial.

Note: 1. Indicate serum on request form.

              2. Label specimen appropriately (serum).

 

Plasma

Draw blood in a lavender-top (EDTA) tube(s). Separate immediately

and send 3 mL of EDTA plasma frozen in a plastic vial.

Note:  1. Indicate plasma on request form.

               2. Label specimen appropriately (plasma).

 

Patient preparation:

                Patient should not be on any Steroid, ACTH, Gonadotropin,

                or Estrogen medications, if possible, for at least 48 hours

                prior to collection.

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.
