Can blood tests diagnose endometriosis?

At this time, blood tests cannot reliably diagnose endometriosis. While markers like CA-125 may be elevated in some people, they’re not specific enough to confirm endometriosis or rule it out, so they aren’t considered a validated diagnostic test.

Research into more accurate biomarkers and molecular testing is active and promising, but these tests aren’t yet ready for routine clinical use.
