U104

U104 is a designation that can refer to several different entities, most notably a submarine and a medical marker.

The U104 submarine was a Type U 104 submarine of the German Imperial Navy, built during World War I. It was laid down in 1916 and launched in 1918. This particular submarine was one of the later models in its class, designed for extended patrol duties. It did not see significant combat service before the end of the war. Following the Armistice, U104 was surrendered to the Allies and subsequently broken up. Details regarding its operational history are limited due to its late commissioning and the cessation of hostilities.

In a different context, U104 is a medical code. This code is used in pathology and laboratory medicine to identify and track specific samples or tests. For instance, U104 might represent a particular type of urine test, a specific cellular analysis, or a marker for a particular condition. The exact meaning of U104 in a medical setting is dependent on the specific laboratory or healthcare system using the code. It serves as an internal organizational tool to ensure accurate record-keeping and efficient processing of medical information.
