What is a common result of hemagglutination in a blood test?

Hemagglutination is a key process employed in laboratory tests, particularly in serology, to identify the presence of specific antigens or antibodies in a sample. In the context of blood tests, hemagglutination occurs when red blood cells clump together due to the binding of antibodies to specific antigens on the surface of the cells. This clumping is particularly useful for determining blood types.

When a sample of blood is mixed with antisera (which contains antibodies against specific blood group antigens), the hemagglutination reaction will demonstrate how the red blood cells from the sample respond. If the blood type matches the antigens present in the antisera, agglutination occurs, signaling a match. This method is fundamental for safe blood transfusions and organ transplants, as compatibility between blood types must be established to prevent adverse reactions.

In contrast, other options such as measuring blood pressure, assessing iron levels, or determining cholesterol levels are unrelated to hemagglutination. Blood pressure measurements involve a sphygmomanometer and are not influenced by antibody interactions. Assessments of iron levels typically require serum tests or other biochemical assays rather than hemagglutination. Similarly, cholesterol levels are analyzed through lipid profiles utilizing enzym
