HemoCue hemoglobin systems

In this product brochure, HemoCue^® provides insights into the differences between photometric and conductivity-based methods for measuring hemoglobin concentration. The photometric method involves a simple chemical conversion of hemoglobin, and the absorbance change is measured with a photometer, offering a direct proportion to hemoglobin concentration. Conductivity-based methods use a formula assuming normal physiological variables, leading to potential limitations when a patient's vitals are not normal, including interference with various substances. Additionally, the brochure emphasizes that the quality of test results is influenced by factors beyond technological limitations and provides details of the range of HemoCue products and solutions available to help reduce errors in hemoglobin testing.
