Pyruvic Acid, Blood
Specimen Type Describes the specimen type needed for testing
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: Special collection tube containing 2.5 mL of 6% perchloric acid (T012)
Specimen Volume: Exactly 1 mL
1. Fasting (at least 4 hours)
2. Special collection tube must be prechilled prior to draw.
3. Draw enough blood directly into syringe to add exactly 1 mL of blood to the special collection tube (prechilled).
4. Once drawn, immediately transfer blood to the prechilled, special collection tube and shake vigorously to mix.
1. Check expiration date before using. Supplied collection tube expires 12 months after preparation.
2. If perchloric acid spills, obtain new, prechilled tube.
Forms: If not ordering electronically, complete, print, and send a Neurology Test Request Form-General (T732) (http://www.mayomedicallaboratories.com/it-mmfiles/neurology-request-form.pdf)
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.

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
