Laboratory tests, imaging tests and etiologic analysis can help determine whether the elevated uric acid in a patient’s body is due to excessive production of uric acid, decreased excretion of uric acid, or both.
1. Laboratory tests: Laboratory tests that can assist in determining the cause of elevated uric acid in the patient’s blood include: urinary uric acid and liver and kidney function tests, in which urinary uric acid refers to the amount of uric acid in the urine, and the test of urinary uric acid can determine whether the elevated uric acid is due to a decrease in the excretion of uric acid.
2. Imaging examination: kidney disease can lead to decreased uric acid excretion, ultrasound examination can check the structure of the kidney and clarify whether there are lesions in the kidney or gouty kidney stone formation.
3. Etiological analysis: blood system diseases, excessive production of organic acids, high purine diet and other factors can lead to excessive production of uric acid, while kidney diseases, drugs and other factors can lead to impaired excretion of uric acid.
Patients can also determine through other methods of uric acid elevation is due to uric acid production or excretion is reduced, it is recommended that patients can go to the regular hospital endocrinology, rheumatology and immunology departments and other related departments for detailed consultation.
