@jeffh Welcome to Mayo Clinic Connect. It is so easy to get caught up in the "what ifs" and "how did this happen", going down the rabbit hole of Dr. Google and not always getting accurate information.

As @collegeprof mentioned, we should look at trends in our lab reports, not just a single result. There can be variables to take into consideration. Were you perhaps not feeling well that day of the labwork? Were you dehydrated? Do you have other health issues that you live with? Was it the same lab to process your bloodwork, were the machines themselves the same? You can see, it could be a combination of all these things! I know it is not easy to be patient, and wait for your NP to give you more insight, is it?

Continue to eat healthy for your situation, get moderate exercise, keep your stress levels at bay best you can. What will you do this weekend to distract yourself? What further questions or concerns can I help you with?
