Test ID: LAA    
Lactate, Plasma

Specimen Type Describes the specimen type needed for testing

Plasma NaFl-KOx

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: Grey top (potassium oxalate/sodium fluoride)

Submission Container/Tube: Plastic vial

Specimen Volume: 0.5 mL

Collection Instructions:

1. Collection must be at least 1 mL in a 2-mL draw tube or at least 2 mL in a 4-mL draw tube.

2. Spin down and separate plasma from cells.

Additional Information: Patient's age and sex is required.

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.
