Because the number of available laboratory tests is bewildering, my discussion will deal only with a few of the simpler procedures which are useful and which can be carried out effectively in a small hospital, in a small group or even in an individual physician's office. The tests, including the series of tests of function, have been chosen for the purpose of recommending only those which have been introduced in the last few years and have proved helpful. A number are primarily diagnostic, while others are employed to evaluate the results of therapy or to study the progress of the disease. In other words, they are tests of diagnosis and tests of progress.
For this discussion certain tests of hepatic function, examinations of the blood and the urine and the value of the erythrocyte sedimentation rate will be considered.
