New Blood Test for Colon Cancer Shows 83% Accuracy in Study

The test offers a more convenient screening option, though it is not yet FDA-approved and requires a follow-up colonoscopy for abnormal results.

A new blood test for colon cancer, showing 83% accuracy in detecting the disease, offers a promising alternative to traditional screening methods.
The test, not yet FDA-approved, is already available in the U.S. for $895, with an FDA decision expected this year.
Guardant Health's blood test requires a follow-up colonoscopy for abnormal results, potentially leading to additional costs.
Experts emphasize the importance of screening options, as current compliance with recommended screenings is below the 80% goal.
The blood test's performance is similar to stool-based tests but less sensitive than colonoscopies, which remain the gold standard.
