Comparison of Immediate and Delayed Blood Alcohol Concentration Testing

The effects of storage time and temperature on blood alcohol concentration were evaluated in this two-part study involving 34 ethanol-negative and 21 ethanol-positive volunteers. Multiple 10-mL Vacutainer® blood tubes containing 100 mg of sodium fluoride and 20 mg of potassium oxalate were collected...

Description
Summary:The effects of storage time and temperature on blood alcohol concentration were evaluated in this two-part study involving 34 ethanol-negative and 21 ethanol-positive volunteers. Multiple 10-mL Vacutainer® blood tubes containing 100 mg of sodium fluoride and 20 mg of potassium oxalate were collected from living persons and subjected to various storage conditions. The time from collection to analysis ranged from 0 to 60 days and storage temperatures ranged from 3 to 20°C. Regardless of the storage conditions, all ethanol-negative samples remained negative (
