Patient Specimen - Paired CSF and serum separated from cells frozen
CSF samples can be stored at 2-8C for up to 7 days. For longer periods store frozen - stable frozen up to 180 days (from Mayo clinic lab website)
Normal CSF ACE (Mass) 0.3 – 7.4 ug/L
ACE mass assay (unaffected by ACE inhibitors) ran on Beckman AU480 analyser at Pathology Queensland Central Laboratory.
Occasionally plasma ACE samples can be forwarded here as well.

Blood contamination of CSF is a problem, because serum levels are 30-130 IU/L. Heparinised plasma OK but serum is less prone to turbidity.
