Understanding Lab Tests for Pelvic Inflammatory Disease
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Pelvic Inflammatory Disease (PID) is an infection of the female reproductive organs, including the uterus, fallopian tubes, and ovaries. It is most commonly caused by sexually transmitted bacteria, particularly chlamydia and gonorrhea. Early diagnosis through appropriate lab testing is crucial for preventing serious complications such as infertility, chronic pelvic pain, and ectopic pregnancy.
Top Recommended Test
Chlamydia and Gonorrhea Test
This test is essential for PID diagnosis as it detects the two most common bacterial causes of the condition. Both chlamydia and gonorrhea infections can ascend from the lower genital tract to the upper reproductive organs, causing inflammation and infection. When left untreated, these sexually transmitted infections are primary triggers for developing PID.

The Role of Lab Testing in PID Diagnosis
While PID diagnosis often involves clinical examination and symptoms assessment, blood tests play a vital role in identifying the underlying bacterial infections that cause PID and monitoring potential complications. Testing helps confirm the presence of specific pathogens and assess the extent of inflammatory response in the body.
Other Relevant Tests
CA-125 (Ovarian Cancer Test)
While primarily used as a cancer marker, CA-125 levels can also be elevated during pelvic inflammatory disease due to the inflammatory response affecting the reproductive organs. This test helps assess the extent of inflammation and can be useful in monitoring the body's response to PID treatment.

Understanding Your Test Results
Positive results for chlamydia or gonorrhea confirm the presence of bacterial infections that require immediate antibiotic treatment to prevent progression to PID or treat existing PID. Elevated CA-125 levels may indicate inflammatory activity in the pelvic region, though this marker is not specific to PID and should be interpreted alongside other clinical findings.
Why Early Testing Matters
Early detection and treatment of the bacterial infections that cause PID is crucial for preventing long-term complications. Untreated PID can lead to scarring of the fallopian tubes, infertility, chronic pelvic pain, and increased risk of ectopic pregnancy. Prompt testing allows for timely intervention and better health outcomes.
