Phenobarbital monitoring in whole blood with a quantitative noninstrumented test.
The AccuLevel phenobarbital test is based on enzyme channeling and immunochromatography. AccuLevel is a noninstrumented test for the quantitative determination of phenobarbital concentration in whole blood. Within-run precision data, with 20 replicates at each of five concentrations, has coefficients of variation (CVs) of 4.7-9.2%. Between-run precision (n = 40) results in a CV of 5.9%. The AccuLevel phenobarbital test is very specific and is unaffected by endogenous substances and blood collection tube anticoagulants. Compared to the Emit method, this test has excellent linear correlation for the quantitation of 104 phenobarbital positive patient samples. Reagents stored at 4-8 degrees C are stable for 15 months with no effect on the assay quantitation. This accurate, precise, and specific test is easily performed in 20 min.
