Testing for the rheumatoid factor (RF) is essential for the diagnosis and treatment of autoimmune diseases, such as psoriatic arthritis. RF levels serve as a sign of autoimmune activity and inflammation, which helps distinguish between various forms of arthritis and inform therapy choices. This in-depth manual describes the usual range, process, and related expenses as it examines the significance of RF testing in psoriatic arthritis. At Kayakalp Global, we stress the value of a precise diagnosis and individualised treatment plans for the optimal management of psoriatic arthritis. Understanding Rheumatoid Factor (RF) An immune system antibody called rheumatoid factor (RF) attacks healthy tissues, causing swelling and harm to tissues. Increased levels of RF in the blood are frequently linked to autoimmune conditions, namely RA. Nevertheless, RF can also be seen in other autoimmune diseases such as Psoriatic Arthritis (PsA) and Sjögren's syndrome. Function in Immune Disorders In autoimmune disorders, the body's own tissues are not recognized by the white blood cells and hence attacked by the immune system, resulting in long-term inflammation and damage to the body. RF contributes to the aberrant response of the immune system, which is a major factor in this process. Although RF is frequently linked to RA, its presence in PsA is less reliable, although it can still yield important diagnostic data. Increased radiofrequency (RF) levels can help identify and differentiate between various forms of arthritis. Although RF levels in PsA may not always be high, they can be used to distinguish the condition from RA …
