title: Determination of theophylline concentrations by AccuLevel.
abstract: Determination of theophylline concentrations in 29 paired venous samples by AccuLevel and EMIT disclosed excellent correlation. Evaluation of precision of AccuLevel by 20 replicate analyses disclosed a coefficient of variation of 3.5%. AccuLevel is an accurate, precise, rapid method of determination of theophylline concentrations in whole blood.
