PTT test high, will the doctor cancel my breast augmentation surgery?

Your surgeon will need to review the results and find out if it's meaningful or not.  If so, sometimes, it's worth repeating, since sometimes tests have errors themselves.

Hello, thanks for your question.  Your surgeon will need to review the test and determine if it's just outside of the normal range, or obviously abnormal.  They will be able to discuss the potential bleeding risk (if any) and whether your surgery should be delayed.
