[|Human|] my mummy  is having her Antibodies antinuclear test is positive so doctor asked her to take other tests and her result is SGTT 29 RAF is negative anti CPP is 3.7 CRP negative and she is having swollen hands and legs with joint pain. Can u please guide us what the problem is.
[|AI|]  Hello, A positive anti-nuclear antigen (ANA), and a history of swollen hands, swollen legs, and joint pains suggest an autoimmune disorder. There are a number of autoimmune disorders which show positive ANA. The closest differential of above-mentioned symptoms is rheumatoid arthritis. Rheumatoid arthritis is characterized by joint pains especially the joints of hands. Rheumatoid factor (RF) is usually positive in rheumatoid arthritis however, it can be negative in many cases. I suggest you consult your rheumatologist for further workup. Hope I have answered your query. Let me know if I can assist you further.
