Fingertip blood is currently considered inaccurate for measuring blood uric acid. Blood uric acid refers to the level of uric acid in the serum and is usually measured in fasting venous blood. Fingertip blood is not venous blood and the results are generally inaccurate. Blood collection sites for uric acid measurement are usually the elbow vein, dorsum of the hand and forearm vessels. Fingertip blood is usually taken from the end of the finger, which is peripheral circulating blood, and is often used to determine blood counts, blood glucose levels, blood type, etc. Therefore, it is not usually used to measure blood uric acid. It is important to fast before having blood drawn for uric acid and not to eat high-fat foods the night before. Blood uric acid test is recommended to fasting to the regular hospital, under the guidance of the doctor for testing.
