Gouty arthritis or other types of arthritis can be determined by clinical manifestations such as redness, swelling, heat and pain in the joints, medical history such as history of hyperuricemia, and ancillary tests such as blood uric acid and urinary uric acid levels. Gouty arthritis is a type of arthritis with clinical manifestations of redness, swelling, heat, pain and joint dysfunction in the affected joints. It is common for a single joint to be involved, with severe pain, often starting suddenly at midnight or early in the morning. There may be a history of hyperuricemia or a family history of gout, and the onset of the disease may be preceded by a high intake of a high-purine diet. Other types of arthritis, such as rheumatoid arthritis, present with swollen, painful and stiff joints, usually without localized elevation of skin temperature, with joint pain aggravated by activity, and may present with multiple joint involvement. There is no previous hyperuricemia, no family history of gout, and cold irritation may precede the onset of the disease. Based on the clinical manifestations and medical history, further auxiliary tests, including blood uric acid, uric acid, arthrocentesis, examination of suspected gouty contents, joint ultrasound, and X-ray examination, are required. If the patient is tested with elevated blood uric acid level, uric acid level, joint cavity puncture synovial fluid microscopy visible urate crystals, joint ultrasound or X-ray examination visible joint destruction, etc. can be determined that the patient is gouty arthritis. It is recommended that patients go to regular hospitals to further improve the relevant examinations to clarify the diagnosis.
