Using the enzyme immunoassay technique (EMIT), we determined the time course of urinary excretion of benzoylecgonine in 16 surgical patients and three volunteers who received intranasal cocaine. After doses varying from 13 to 130 mg, the test for benzoylecgonine was positive in 1 to 4 h, peaked at about 10 to 12 h, remained positive for 18 to 27 h, and became negative after about 17 h. This inf...
We describe specific EMIT homogeneous enzyme immunoassays for amitriptyline, nortriptyline, imipramine, and desipramine in patients' serum samples. Before analysis, an easily performed extraction step involving the use of 500 microL of sample and a 1-mL disposable column eliminates cross-reacting polar metabolites. The range of the standard curve for the first three drugs is 25 to 250 microgram...
