Mitzi Krockover: CA-125 blood test is less effective for Black and Native American women than White women

Mitzi Krockover, host of Beyond the Paper Gown Podcast, posted on LinkedIn:

“Critical finding:

The standard CA-125 blood test for ovarian cancer is 23% less effective for Black and Native American women compared to white women.

This JAMA Network Open study reveals why research on medical disparities is essential: Tests developed decades ago in predominantly white populations may fail to serve all patients equally.

With ovarian cancer survival dependent on early detection, and recent political pressures threatening diversity-focused medical research funding, these findings couldn’t be more timely.

The researchers have proposed new thresholds that would work better across all populations—exactly the kind of solution we need but might lose if we abandon research that considers ethnicity and sex.

Medicine must be evidence-based for ALL patients. This isn’t about politics—it’s about saving lives and all that entails for our society and economy.”
