What are the four tests for rheumatism

The four tests for rheumatism mainly include four indicators: anti streptolysin O, rheumatoid factor, C-reactive protein, and erythrocyte sedimentation rate. The four items of rheumatism are a combination of basic examinations used clinically to assist in the diagnosis of rheumatic immune diseases. Elevated levels of anti streptolysin O usually indicate recent or past A hemolytic streptococcal infection, which is associated with diseases such as rheumatic fever and acute glomerulonephritis. Rheumatoid factor positivity can be seen in rheumatoid arthritis, but it may also occur in other autoimmune diseases such as Sjogren's syndrome and systemic lupus erythematosus. Some healthy elderly individuals may also show low titer positivity. C-reactive protein is an acute phase response protein that rapidly increases during inflammation, infection, or tissue damage, and its level can reflect the degree of inflammatory activity in the body. Erythrocyte sedimentation rate, also known as erythrocyte sedimentation rate, accelerates when there is inflammation, infection, tumor, or autoimmune disease in the body. However, this indicator has low specificity and needs to be comprehensively judged in conjunction with other examinations. These four tests work together to help doctors preliminarily screen for abnormalities in the rheumatic immune system, but diagnosing specific diseases usually requires a combination of clinical symptoms, imaging examinations, and more specific autoantibody testing. Before undergoing the four rheumatology tests, it is generally not necessary to have an empty stomach, but it is recommended to maintain a normal daily routine, avoid vigorous exercise and alcohol consumption, so as not to affect the results of C-reactive protein and erythrocyte sedimentation rate. If there are abnormalities in the examination results, do not make judgments on your own. You should seek medical attention promptly at the rheumatology and immunology department. The doctor will make a comprehensive evaluation based on your specific symptoms such as joint swelling and pain, morning stiffness, fever, rash, etc. Pay attention to keeping warm and avoiding excessive fatigue in daily life, and engage in appropriate joint function exercises to help maintain joint health.
