Blood and urine are often tested to find the cause of health problems. But other body fluids also can be tested. Most of these fluids help organs and joints—and the membranes around them—move smoothly. Sometimes a health problem can cause too much fluid to build up in part of the body. The fluid can be tested to look for the reason for the buildup.
Some of the most common body fluids that are tested are:
Tests on body fluids can be done to look for signs of infection or inflammation. For example, Gram stain and culture and sensitivity tests can find the type of bacteria that is causing an infection. The tests also can show what kind of medicine can best treat the infection.
Tests of body fluids also can be done to look for cancer or another disease.
In most cases, a needle is used to take out some fluid.
Genital tests are done by taking a swab or sample of fluid. For example, a doctor collects cervical mucus from the vagina or cervix in a way similar to a Pap smear. Then tests can be done on the mucus.
