What color tube top is typically associated with immunohematology?

The pink tube top is typically associated with immunohematology because it is used for blood banking and crossmatching procedures. This color is specifically designated for the collection of whole blood and serum samples that are critical for blood transfusions, compatibility testing, and other immunohematological investigations. The use of pink tops helps to clearly identify specimens that require special handling and processing in the laboratory, ensuring that the workflow is efficient and that patient safety is prioritized during transfusion practices. This standardization is important in the healthcare setting, so that proper protocols are followed and there is minimal risk of errors in blood administration.
