Reference Values

Normal:  < 10 mg/dL (None Detected)
Critical result (automatic call-back): any detectable amount (level of detection is ≥ 10 mg/dL).

Any first-time critical value ≥ 10 mg/dL will be confirmed with gas chromatography (GC) to confirm the results. Subsequent critical results obtained on the same patient within 96 hours of the first confirmed critical do not require GC confirmation.

NOTE:  Propylene Glycol interferes with this assay.  Specimens containing propylene glycol should not be monitored using this assay.
