What is the role of the pink tube in laboratory testing?

• A. Fasting blood sugar tests
• B. Type and Cross Match
• C. ESR tests
• D. Kidney function tests

Answer: (B)

The pink tube is specifically designed for blood collection related to type and crossmatch testing. This testing is crucial in blood transfusion processes, as it determines the compatibility between a blood donor and a recipient. The tube typically contains EDTA as an anticoagulant, preventing the blood from clotting and allowing for accurate laboratory analysis of the blood type and potential antibodies. The importance of a pink tube in this context is underscored by the critical nature of accurate typing and crossmatching in ensuring the safety of blood transfusions. While other tests can require different types of tubes depending on the necessary additives and the specific requirements of the tests, the pink tube's clear emphasis on compatibility testing makes it unique in its application. Other options, while related to various lab tests, do not require the pink tube for their procedures. For instance, fasting blood sugar tests typically utilize a gray tube, ESR tests often use a lavender tube, and kidney function tests generally require a different tube type altogether, usually a serum separator tube. Thus, the distinct role of the pink tube in facilitating type and crossmatching stands out clearly among the choices.
