Test ID: TOBR    
Tobramycin, Random, Serum

Specimen Type Describes the specimen type needed for testing

Serum Red

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.

Collection Container/Tube: Red top

Submission Container/Tube: Plastic vial

Specimen Volume: 1 mL

Collection Instructions:

1. Spin down within 2 hours of draw.

2. Serum for a peak level should be drawn 30 to 60 minutes after last dose (order TOBP / Tobramycin, Peak, Serum). Serum for a trough level should be drawn no more than 30 minutes before next scheduled dose (order TOBT / Tobramycin, Trough, Serum).

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.
