Patient: I’m 23 male my ra factor is 100 positive my ccp is 16 negative , sed rate 12 negative, and crp .13 negative , I have high cholesterol 267 , trigercydes are 212, ldl 191 , hdl 34, vldl 42, chol/hdl 7.9, I read online high blood fats can cause a positive ra factor , would this be high blood fats ? I had a ct scan 2 months ago every thing came back unremarkable, besides a fatty liver , what kind of cancer is connected with a ra factor ?
Doctor: Hello.Welcome to Ask The Doctor. We are here to help you.No blood fats are not going to cause false positive Rheu matoid Factor. Since your Anti – CCP is negative so we can say that you don’t have Rheumatoid Arthritis at present.Around 10% of Healthy people can get R-Factor positive and so is not a trust worthy test to diagnose Rheumatoid Arthritis.Moreover, diagnosis of Rheumatoid Arthritis is mostly made clinically as a lot of people have Rheumatoid Arthritis but they get R-Factor negative and we call it Sero negative rheumatoid arthritis.A number of conditions are associated with positive RF tests:1.Sjogren’s syndrome or cryoglobulinemia, 2.Bacterial endocarditis3.Tuberculosis4.Sarcoidosis5.Malignancies- they can be any Malignancy. It’s not like that any particular Malignant condition causes false positive R-Factor.Since you have been investigated well with scans I suppose you fall under those 10% of population who get it positive normally.Your no investigation mentioned is suggestive of Rheumatoid Arthritis.If you were my patient I would have not investigated you further. I would have wait for any new symptoms.It is a likely possibility that you might not ever get any symptoms. But in future if you get any joint pains then you should get a repeat Anti-CCP Antibody test.Also, I would advise you to get Anti-Nuclear Antibody (ANA) test done to rule out any autoimmune disorder that can also cause false positive R-Factor.This is my opinion based on the available details. You can share my opinion with your treating doctor.I hope you get help by my answer.Good Luck.
