Step-by-step explanation:
A light-blue-topped tube is most often associated with tests in the Medical department. The color of the tube indicates the type of test or sample being collected.

For example, light blue tubes are commonly used for coagulation tests, such as prothrombin time (PT) and activated partial thromboplastin time (aPTT).
