My 3-year-old nephew has had elevated CRP levels 4-5 times in the past 8 months, but all other reports, like his CBC and urine tests, are normal. His CRP is currently at 20. It always seems to rise, and the pattern has been that he had a fever when it was high, but this time hes just not eating well and vomiting. Can you help me understand why his CRP keeps going up and what should be done?
