Cervix needle sample

Culdocentesis is a procedure which checks for abnormal fluid in the space that is just behind the vagina, the posterior cul-de-sac. This procedure is done when pain occurs in the lower abdomen and pelvic regions, and other tests suggest that fluid may be present in the cul-de-sac. The test may also be done when a ruptured ectopic pregnancy or ovarian cyst is suspected.
