Alcohols : 0090131

Mnemonic: ALCT

Methodology: Quantitative Gas Chromatography
Performed: Sun-Sat
Reported: 1-2 days
Specimen Required: Patient Prep: For medical purposes only.

Collect: Plain red. Also acceptable: Lavender (EDTA), pink (K2EDTA), or gray (sodium fluoride/potassium oxalate).

Specimen Preparation: Do not freeze whole blood. Separate serum from cells within two hours of collection. Transfer 2 mL serum or plasma to a tightly-capped tube to minimize alcohol loss. (Min: 0.3 mL) Specimens collected in gray (sodium fluoride/potassium oxalate) may be transported in the original container.

Storage/Transport Temperature: Refrigerated.

Stability (collection to initiation of testing): After separation from cells: Ambient: 1 week (if tightly capped); Refrigerated: 2 weeks (if tightly capped); Frozen: 1 month (except whole blood)
