[Diagnostic potentials of studying the ESR]

Specific (tuberculin, adrenalin) and nonspecific (ultrasound, phenol) in vitro exposures of the blood improve the diagnostic informativeness of the red cell sedimentation rate measurements. Similarity of the results of measurements, carried out by the suggested and the reference techniques in more than 550 patients, gives grounds to employ the suggested modifications of tuberculin diagnosis, of detecting a beta-adrenodependent bronchospasm, of assessing the pattern and the activity of an inflammation in pneumonias. Practical and statistical rationale for the suggested methods is given.
