Introduction

Under normal circumstances, RF in medicine refers to rheumatoid factor. After testing for rheumatoid factor, a comprehensive evaluation combining clinical symptoms and other examination results is necessary, as a single indicator alone cannot confirm a diagnosis. Individuals with positive rheumatoid factor should undergo regular follow-up tests to monitor changes in the指标 (indicator) and disease progression. If symptoms such as joint pain or swelling occur, prompt medical attention should be sought to avoid delaying treatment.

Generally speaking, RF in medicine refers to rheumatoid factor. Detailed explanation is as follows:

RF in medicine refers to rheumatoid factor, a type of autoantibody produced by the human immune system, which is commonly associated with autoimmune diseases such as rheumatoid arthritis. When the immune system functions abnormally, it mistakenly attacks the body's own tissues, resulting in the production of RF. Clinically, the results of rheumatoid factor testing can assist in determining the presence of related diseases. Particularly in the diagnosis of rheumatoid arthritis, a high positive rate of rheumatoid factor provides important reference information for disease diagnosis, helping doctors better understand the patient's condition.

After testing for rheumatoid factor, a comprehensive evaluation must be conducted in combination with clinical symptoms and other test results. A single indicator alone cannot be used to diagnose a disease. Patients with positive rheumatoid factor should undergo regular follow-up tests to monitor changes in the indicator and disease progression. If joint pain, swelling, or other discomfort occurs, timely medical attention should be sought to avoid delayed treatment. Daily attention should be given to joint protection, avoiding excessive fatigue and maintaining good living habits.
