Alpha-1-Antitrypsin Clearance, Feces and Serum

Specimen Type Describes the specimen type needed for testing

Fecal
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.

Feces and serum are required.

 

Blood must be drawn during the stool collection period.

 

Specimen Type: Serum           

Collection Container/Tube: Red top or serum gel

Submission Container/Tube: Plastic vial

Specimen Volume: 1 mL

 

Specimen Type: Stool

Container/Tube: Stool container (Supply T291)

Specimen Volume: Entire collection

Collection Instructions:

1. Collect a 24-hour stool collection.

2. If no specimen is obtained in 24 hours, extend collection to 48 to 72 hours. Note time frame.

3. See Stool Collection Information Sheet in Special Instructions.

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.
