It has been well known that cephalosporins derivatives interferes with the nitroprusside reaction which is applied for detection of acetone. In order to measure acetone semiquantitatively in urinary samples containing these interfering materials, we deviced a simple apparatus. of which principle was as follows: a cotton boll being suspended from the top of a glass tube captured vaporized acetone which was arisen from urine laid on the bottom of the tube by boiling it and the content of acetone in the cotton boll was measured using a testing stick.
The validity of this method was tested using 33 urinary samples which contained acetone as well as the cephabsporin derivatives. The method was revealed to be satisfactory for a clinical use.
