Hi there. I have been having symptoms, including blood in my stool, for about 2.5 months now. I am going to be having a colonoscopy sometime next week (probably -- depending on how quickly the insurance moves to approve everything). In the meantime, I have had some blood work done, which included a check of the SED rate. From my understanding, this test would show an elevated number if there were to be an inflammation etc. in my body. Since this came back "within normal range", can I rule out cancer?
Thanks to anyone with information!
