summary

Rheumatoid arthritis has a lot of similarities with ordinary arthritis, but the essence is different. For a time, my grandfather often had joint pain, but later he found that it was rheumatic. Here's how to diagnose rheumatoid arthritis.

How to diagnose rheumatoid arthritis

First, in the laboratory, the positive rate of serum rheumatoid factor in patients with rheumatoid arthritis only accounts for about 70% of rheumatoid arthritis, but the positive rate of rheumatoid factor can not be determined, It must be rheumatoid. About 5% of normal healthy people or the elderly can also be positive for rheumatoid factor. If rheumatoid factor is a positive result, we should further check the titer of rheumatoid factor. The higher the titer, the more accurate the diagnosis of rheumatoid arthritis is.

Second: there is at least one swelling and effusion in the proximal metacarpophalangeal interphalangeal joint and wrist joint, that is, there is swelling or effusion. The most frequently involved joints were wrist, proximal interphalangeal joint, metacarpophalangeal joint, metatarsophalangeal joint, knee, ankle and elbow, followed by shoulder and hip. These are very useful for the diagnosis of rheumatoid arthritis.

Third: the proximal interphalangeal joint was fusiform swelling, the most common. The second is metacarpophalangeal, toe, wrist, knee, elbow, ankle, shoulder and hip joint, and the muscle near the joint is stiff and atrophic.
