ABO and Rh typing are performed in which laboratory section?

1. Hematology

2. Blood bank

3. Chemistry

4. Cytology

The correct answer is: Blood bank

ABO and Rh typing are performed in the blood bank section of the laboratory. This area specializes in the collection, testing, processing, and storage of blood components. ABO and Rh typing are critical for blood transfusions, organ transplants, and determining blood compatibility, which are all vital tasks of the blood bank. In this context, the blood bank performs serological tests to identify the blood group and Rh factor, ensuring that patients receive blood that matches their specific requirements. This testing is essential for patient safety, as incompatible blood transfusions can lead to serious reactions. Other laboratory sections, such as hematology, focus on blood cell counts and blood disorders; chemistry typically involves analyzing chemical components in bodily fluids; and cytology examines cells for abnormalities, but they do not specifically perform blood typing.
