Modern medical advances necessitate the application of many specialized procedures in diagnosis in addition to the usual routine analysis carried out in chemical laboratories. In this volume, Dr. Abelin, a noted Swiss investigator, discusses all the special chemical procedures that have been devised in recent years. Specific directions, with brief critical comments on the determination of steroid hormones, 17-ketosteroids, gluco-corticoids, antidiuretic hormone of the pituitary, histamine, trace elements (arsenic, lead, iron, iodine, silicon, copper, mercury, and zinc), proteins, creatine, galactose, inulin, fructose, 3-carbon acids, alcohol, porphyrins, phosphatases, carbon monoxide, p-aminosalicylic acid, thiocyanate, bishydroxycoumarin (dicumarol®), and chloramphenicol (chloromycetin®) in blood, urine, and other body fluids, are discussed. The procedures are described lucidly in easily read German. The selection has been adopted from the best available methods as described in the world literature, and all procedures are up-to-date.
