Test ID: CTSA    
Ceramide Trihexoside/Sulfatide Accumulation in Urine Sediment, Urine

Specimen Type Describes the specimen type needed for testing

Urine

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.

Container/Tube: Plastic, 60-mL urine bottle

Specimen Volume: 50 mL

Collection Instructions: Collect a first-morning, random urine specimen. If <50 mL from first-morning collection, continue collection until specimen volume is met.

Additional Information: Indicate patient's age and sex.

Forms: If not ordering electronically, submit a Biochemical Genetics Request Form (Supply T439) with the specimen.

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.

30 mL (If <30 mL is received, test will be cancelled.)

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
