Which of the following best describes the physical appearance of a hemolyzed sample?

A hemolyzed sample is characterized by the release of hemoglobin from red blood cells into the serum or plasma when the cells are damaged. This process results in a reddish or pinkish discoloration of the sample. The presence of hemoglobin gives the serum or plasma that distinct color, which is why this characteristic defines hemolysis, making it easy to identify.

In contrast, a cloudy and yellow sample typically suggests the presence of lipids or bilirubin but does not indicate hemolysis. Clear and colorless samples, on the other hand, are indicative of normal serum or plasma with no signs of hemolysis or other issues. A dark brown color could suggest the presence of methemalbumin or other irreversible hemolysis but is not a direct indicator of the classic appearance of a hemolyzed sample. Understanding these color indicators is crucial for medical technologists when evaluating specimens for hemolysis and potential impacts on laboratory results.
