I got false negatives from both Galleri and Signatera 2 weeks before MRI spotted a 2cm malignant tumor recurrence on my pancreas. Not impressed…

Thanks for the info on false negatives. I am taking these tests to check for recurrence of bladder cancer. Mri shows cloudy, possibly scar tissue from previous operations.
Apparently these tests are changing and so are numbers of false positives and negatives. Don't know what to think????
