In the ED setting, few laboratory tests prove to be valuable in the diagnosis of endometriosis.

A complete blood count (CBC) with differential may help to differentiate pelvic infection from endometriosis and to assess the degree of blood loss, if any.

Urinalysis and urine culture should be sent if urinary tract infection (UTI) is in the differential diagnosis.

Cervical Gram stain and cultures should be considered, because sexually transmitted diseases (STDs) can also cause pelvic pain and infertility.

Beta human chorionic gonadotropin (HCG) can rule out pregnancy and its complcations.
