the monocyte was H10 the range is 2-8. what does this mean?

I am not a doctor, but my understanding it that is pretty normal so I don't think that there's much for you to be concerned about. Ultimately, though, it might be a good idea for you to talk to a doctor about this because I think that it's clearly a concern for you. Like I said, it doesn't appear to be an issue, but I think a medical professional would be able to confirm that for you. PLease let us know what the results turn out to be!
