Gout examination items are: 1. Lipid examination including blood cholesterol, triacylglycerol, high and low density lipoprotein (HDL, LDL) and very low density lipoprotein (VLDL), etc. If possible, apolipoprotein determination can be done. 2.Glucose Fasting blood glucose and two-hour postprandial blood glucose measurement should be done; if necessary, glucose tolerance test should be performed to detect glucose metabolism disorder and hidden diabetes at an early stage. 3.Liver and kidney function tests to establish whether there is gouty nephropathy and liver lesions. 4.Cardiovascular and cerebrovascular function tests: electrocardiogram, echocardiogram, cardiac function measurement, cerebral hemogram and other routine tests can be performed. In addition, fundus examination to observe whether there is retinal arteriosclerosis in the fundus can also be used as one of the easy methods to detect arteriosclerosis. 5.Joint X-ray For patients with gouty arthritis attack, joint X-ray should be done. To understand the extent of joint lesions and to provide indirect evidence for the diagnosis of gout. 6.Urological X-ray can detect kidney, ureter and bladder stones at an early stage, and observe the functional status of both kidneys and the shape of renal mons and ureter to establish the presence of hydronephrosis and obstruction. Since uric acid stones can be transmitted by X-rays, most gout patients cannot be detected by abdominal X-rays alone. An intravenous renal pelvis examination is also necessary. If the stone can be found on a plain abdominal X-ray, it indicates that the gout stone contains not only uric acid but also calcium phosphate or calcium oxalate, which is a mixed stone. 7.Puncture or biopsy Gout patients with subcutaneous nodules in the hands, feet, ears and joints or other parts of the body should routinely undergo puncture or biopsy to find out whether they contain urate crystals, which is valuable for establishing the diagnosis. In addition, ultrasound and CT examinations are also valuable in the diagnosis of urinary stones. If the patient cannot tolerate intravenous pyelogram, B-mode ultrasound or CT examination may be an option.
