If you suspect that you have gout, what tests can confirm the diagnosis

For people who are suspected of having gout, there are several medical tests that can help confirm the diagnosis:

1. Blood uric acid level test: Uric acid in the blood is one of the purine metabolites. By measuring the concentration of uric acid in the blood, doctors can tell if hyperuricemia or gout is present.

2. Joint ultrasound: Joint ultrasound is a non-invasive diagnostic method that can help determine whether there is gout-related arthritis and inflammation. It can show changes in the internal structure of the joint and distinguish it from other diseases.

3. X-ray examination: X-ray examination is usually used to rule out other possible causes of joint pain, such as fractures, osteoporosis, etc.In some cases, your doctor may recommend X-rays if tophi or other complications are suspected.

4. Joint biopsy during a gout attack: This is a less invasive test in which a sample of synovial fluid is taken during an acute attack of gout for analysis. This can help determine the presence of uric acid crystal deposits and further assess the severity of the condition.

5. Other auxiliary examinations: Depending on the specific situation, the doctor may also ask for other auxiliary examinations such as renal function tests, liver function tests, electrocardiograms, etc., to comprehensively assess the patient's health status.

These tests need to be performed by a medical professional according to the patient's specific situation. If you have concerns or symptoms, seek medical attention and consult a medical professional.
