[Simultaneous determination of antiepileptic drugs in clinical laboratories: Problems of quality control and standardization (author's transl)].

Methods for determination of antiepileptic drugs in clinical laboratories are discussed with respect to precision, constant error control and economy. Experimental data for reproducibility and standardization are presented for gas chromatographic and photometric methods. Methods for choosing the most suitable procedure for any of the common analytical tasks that may arise in the clinical laboratory are recommended.
