Specimen Collection
SPECIMEN:
2.0 mL is the recommended volume; a minimum of 0.6 mL of CSF is required, but this is insufficient for a duplicate analysis (recommended).
Only applies to samples collected at AKH.
Send on ice
within 5 minutes
to the laboratory.
Please arrange with the laboratory prior to sending the specimen.
As pyruvate is unstable, falsely low levels may be seen if samples do not reach the laboratory on ice, within 5 minutes of sampling.

Specimen Transport Instructions for Referring Laboratories
CSF
samples must be deproteinised within 5 minutes of collection and stored at 2-8C.
Deproteinisation should be performed in duplicate where possible.
Deproteinisation procedure:
To a plastic pilot tube add:
1mL of 0.6mol/L Perchloric acid
0.5mL of sample
Mix well
Please indicate on form whether deproteinisation has been performed.
