Individual tests

A blood type can be classified into four common groups known as the ABO system: A, B, AB, or O. A second system, the Rh system, determines if the blood type is Rh-positive or -negative. Blood typing is a common test before blood transfusions, tissue transplants, and during pregnancy.

Urinalysis is often used to check for urinary tract infections, kidney problems, or diabetes. You may also have one during a checkup, if admitted to the hospital, before surgery, or if pregnant. It can also help monitor medical conditions and treatments.
