This edition is thoroughly revised. The book has been written especially for the man in practice and its usefulness is virtually limited to that group. The authors are practical and conservative in the presentation. They have not attempted a complete discussion of the entire field of applied biochemistry but have limited themselves to the commoner and more generally useful tests. The text covers the subjects of collection and preservation of samples of blood, urine, feces and spinal fluid; basal metabolism; mechanism of neutrality regulation; glycosuria; albuminuria and tests of renal function; analysis of gastric contents; tests of hepatic function and of the cerebrospinal fluid; chemical tests in pregnancy; blood calcium and phosphorus, and the blood sedimentation rate. Technical methods are given in an appendix instead of the text. All the discussions are concise and clearly presented from the point of view of medical practice.
