Hemolysis in collected blood can cause a falsely decreased value for:

D) total protein

Question

Quizplus · Accepted Answer

Hemolysis in collected blood samples can cause the release of intracellular contents into the plasma or serum, artificially increasing the concentration of certain analytes. However, for hemoglobin, the measurement is typically done on whole blood, and hemolysis can lead to a loss of intact red blood cells, potentially causing a falsely decreased hemoglobin measurement if the hemolysis is severe and not accounted for in the analysis.
