The test that is not typically associated with the Transfusion Science Lab is glycolated hemoglobin. This test measures the average blood glucose levels over a period of time and is primarily used to monitor diabetes management. It assesses how well a person's blood sugar levels have been controlled over the past two to three months by measuring the percentage of hemoglobin that is coated with sugar.

In contrast, tests such as crossmatch, group and Rh determination, and direct antiglobin test are directly related to blood transfusions and compatibility. Crossmatching is essential for ensuring that a donor's blood is compatible with a recipient's blood before transfusion. Group and Rh testing identifies the blood type and Rh factor of an individual, which are critical components in transfusion science. The direct antiglobin test is used to detect antibodies that are bound to the surface of red blood cells, assisting in diagnosing conditions like hemolytic anemia and ensuring appropriate blood transfusion practices.

Thus, glycolated hemoglobin does not align with the primary functions of the Transfusion Science Lab, which focuses on blood group determination, compatibility testing, and managing blood products for transfusions.
