Aid in assessment of the etiology of anion gap acidosis. Determine whether ethylene glycol poisoning exists.
Timing of specimen collection: Dependent on time of exposure - test upon presentation to hospital.
Plain red. Also acceptable: Lavender (K2 or K3EDTA) or pink (K2EDTA).
Separate serum or plasma from cells within 2 hours of collection. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL) When drawing a blood specimen for ethylene glycol testing, use a nonalcohol-based cleanser at the venipuncture site.
Whole blood. Gel separator tubes, light blue (citrate), or yellow (SPS or ACD solution).
After separation from cells: Ambient: 1 week; Refrigerated: 1 week; Frozen: 1 month
