Hi My Name Is Pete , My Wife Brenda ,

Hi my name is Pete , my wife Brenda , just saw some blood work results online and is alarmed. Her C-reactive protein count was 21 and we see where anything over 10 requires additional testing . Can you give me any information on why this score is so high and what is the highest it can go. She is a breast cancer survivor and within the last 2 months had a pet scan done that showed no signs of cancer .
