My RA factor is 412 butand my Sed is normal. what could cause such a high RA factor? It was checked 3 times just to make sure it wasnt a mistake. Thank You
An interesting question. Why was the RA factor drawn in the first place? I assume you were having some joint pain. A positive rheumatoid factor can be found in other conditions besides RA, like chronic infections. However, a very high level like this is a clue that RA MIGHT (not definite but MIGHT) develop in the future, even if it is not there now. So, someone with a very positive RF should be seen by a rheumatologist and followed periodically. IF there is already joint pain present, then a visit to a rheumatologist is a must !!
