Dear Deepthought,
I’ve had the following message from one of our Oncologists.
Are you aware of antibiotics interfering with tumour marker assays in particular CA125?
I have a pt whose CA125 was progressing in a very definite trend when it suddenly jumped up on Amoxycillin and then returned to the trend when off the antibiotics….
I cannot see how this would be a factor but thought I would ask..pt also very keen to check
We are using Beckman so it’s actually Ov-Monitor.
Has anyone come across this?
Michael
P.S. No, Tim, the answer isn’t 42.
