Recently I had elevated sgpt/sgot levels. My Dr. Had them retested every 4 weeks to follow them. I do not have any form of hepatitis. My Dr. Tested me for all forms when my first test came back elevated. This time when I picked up the results they were normal but there was a comment made by the lab that said "rbc's present, chemistry results may be affected"
what does this mean and how does that happen.

Thanks!
