Ovarian cancer blood test may miss cases in Black and Native American patients, study finds.
A new study published in JAMA Network Open reveals that a common blood test for ovarian cancer, the CA-125 test, may miss some cases in Black and Native American patients, leading to delayed treatment.
Researchers found these patients were 23% less likely to have elevated CA-125 levels at diagnosis compared to white patients, suggesting that current test thresholds are too high for these populations.
The study proposes a new, lower threshold for the test to improve accuracy and reduce healthcare disparities.
