Final answer:
A test that measures the liver's ability to handle bilirubin is called a Liver Function Test (LFT), which includes various metrics such as bilirubin levels to assess liver health.
Step-by-step explanation:
A test that measures the ability of the liver to take up, process, and secrete bilirubin into the bile is known as a Liver Function Test (LFT). Among the tests included in an LFT are measurements of various substances in the blood, such as alanine aminotransferase (ALT), alkaline phosphatase (ALP), and bilirubin, which are indicative of liver health. While tests like ALT and GGT (Gamma-Glutamyl Transferase) are used to assess liver damage and function, they do not directly measure bilirubin processing. The liver's capacity to handle bilirubin is particularly assessed through tests related to bilirubin itself, such as direct bilirubin and total bilirubin levels.
