THE USE OF PHOTO-ELECTRIC TURBIDOMETRY IN THE DETERMINATION OF RED CELL COUNTS, HEMATOCRITS, AND HEMOGLOBIN

Abstract

1. Blood turbidometry is recommended as a screening technic for distinguishing between anemic and nonanemic individuals. 2. Blood turbidometry must be supplemented by other technics for an exact diagnosis of the type of anemia. However, with such help it makes its own contribution to the accuracy of the diagnosis. 3. Blood turbidometry alone would seem to be capable of following an anemic individual’s response to therapy once the proper diagnosis is established. 4. Determination of hemoglobin concentration by turbidometry appears as a distinct possibility. However, further investigation is necessary to validate its utility. 5. Evidence is accumulated that the shadow-volume relationship is a constant in several species.
