Abstract:
The direct application of 20 microliters of serum to thin layer chromatograms was a rapid and sensitive method for the determination of theophylline. Ten common drugs were shown not to interfere. A comparison with the enzyme immunoassay values obtained in an independent laboratory showed the utility of the method.
