title: Superabsorbent polymers--media for the enzymatic detection of ethyl alcohol in urine.
abstract: Superabsorbent polymers are shown to be an excellent medium for the detection of enzymes used in enzyme assays. They offer increased sensitivity of 2-10 times over conventional blotter medium. Their usefulness is demonstrated with a quick, inexpensive, visual test for alcohol in urine with sensitivity approaching 0.001% (w/v). Alcohol levels in 500 random urine samples were determined and the levels ranged from 0.06 to less than 0.001%, with the majority of positives being near 0.005%.
