Do blood or saliva tests replace imaging or surgery for diagnosis?

Blood and saliva “biomarker” tests (including microRNA-based panels) are an exciting area of research, but they do not currently replace a full clinical evaluation or established diagnostic tools. Right now, symptoms, history, and exam findings still matter, and imaging may be used to look for signs of conditions like endometriosis or related pelvic disease.

Some patients may still need a procedure to confirm what’s going on and to treat disease at the same time, especially when imaging is normal or symptoms don’t match the scan results. Many biomarker panels are still being studied for accuracy, consistency across labs, and how well they perform in real-world patients.
