I'm 23 male my ra factor is 100 positive my ccp is 16 negative , sed rate 12 negative, and crp .13 negative can high blood fats cause + ra factor?

I'm 23 male my ra factor is 100 positive my ccp is 16 negative , sed rate 12 negative, and crp .13 negative can high blood fats cause + ra factor?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, rheumatoid factor is not a specific marker for rheumatoid arthritis. It can be positive in many situations, including recovery from infection. High blood fat per se is not a cause of +RA factor. ...Read more

My blood test for rfigm was 176 the normal range is 0-25. Would this indicate a positive RA result?

My blood test for rfigm was 176  the normal range is 0-25. Would this indicate a positive RA result?

Yes: False positives sometimes occur, but those are usually not this high. The blood test doesn't equal a diagnosis of rheumatoid arthritis all by itself, but if you have painful, stiff, swollen joints, that is the most likely diagnosis. See a rheumatologist - the sooner the better. ...Read more

Would 176 RA IgM factor be considered a low positive for rheumatoid factor. What would be considered a positive level. My ccp level is normal.

Would 176 RA IgM factor be considered a low positive for rheumatoid factor. What would be considered a positive level. My ccp level is normal.

It is positive: The level is not as important as what is your clinical examination and other findings. The positive rheumatoid factor by itself does not mean you have arthritis. There are other things that you rheumatologist will look forward to help clarify whether the positive rheumatoid factor is due to rheumatoid arthritis or something else. ...Read more

I had a positive ANA test and positive smith antibodies. Will they find ra?

I had a positive ANA test and positive smith antibodies. Will they find ra?

Lupus: A high-titer ANA and a positive anti-sm (smith) usually means systemic lupus rather than rheumatoid arthritis. This is much more manageable today than in the past. No lab means much in isolation, and your physician ordered these labs because he/she suspected lupus. If the diagnosis is established, you'll probably want to join a community group for people with sle. Good luck. ...Read more

Does ANA 1:320 make diagnosis of RA more definitive? My RF was negative but I have multiple symptoms over 6 months. ANA positive 1:320

Does ANA 1:320 make diagnosis of RA more definitive? My RF was negative but I have multiple symptoms over 6 months. ANA positive 1:320

No: ANA actually isn't something we expect to be positive in rheumatoid arthritis. Your physician is thinking about lupus as a possible explanation, I'll bet. I'm sorry you're having this illness and difficulty in getting diagnosed, but this is common. Usually the nature of a systemic immune disease such as lupus or RA becomes clear over time unless it remits on its own. ...Read more

I did an ra-factor test 2 and half year back and it was negative so if I do it now will it be positive(can it b positive after 2 n half year tym)?

Maybe: You do not mention anything about your symptoms. A positive rheumatoid factor is not necessary for a diagnosis of ra. The ccp antibody is a more specific diagnostic test. A rheumatoid factor can be negative early in the disease and become positive weeks or months later. ...Read more

If I was diagnosed positive for ra, can I delay or prevent it ?

Possibly: You may want to get tested for gluten sensitivity and leaky gut. I know it sounds like an unlikely casue for ra, which is an autoimmune disease, but there is a growing body of evidence being published suggesting there is a correlation between sensitivity to a protein found in wheat, rye and barley (gluten), intestinal permeability (leaky gut) and autoimmune diseases like ra. ...Read more

29 yo. Positive c reactive protein. They've diagnosis me with ra. Can this diagnosis be wrong? I've tried the medicine, but had no response.

29 yo. Positive c reactive protein. They've diagnosis me with ra. Can this diagnosis be wrong? I've tried the medicine, but had no response.

Good question: Ra is diagnosed primarily by what your symptoms are. Typically RA patients have pain in small and large joints on both side of your body. Not all of the joints need to be symptomatic at once. 30 min to 1 hour of joint morning stiffness is typically present. The labssuch as crp, rf, ccp, ESR , may or may not help. If you have ra, it often takes a while to find the right medication or combo to work. ...Read more

What does this mean doc- cra positive. Uric acid 5.7 RA negative?

Lab results: I don't know about a "cra" blood test. There's a standard CRP test, for c reactive protein. CRP is a marker for inflammation. An elevated CRP means that you have inflammation somewhere in your body from anything from a fall to a infection. Uric acid of 5.7 if you are not taking gout medicine you likely do not have gout. Ra neg - you do not have rheumatoid arthritis. :). ...Read more
