What does the uric acid test check?

In life, many people usually don't pay attention to their diet, especially those with high uric acid. In addition to regular physical examinations every year, they also need to pay special attention to their diet. In fact, there are many precautions when going to the hospital to check uric acid. If you don't pay attention to your diet, it will affect the results of the examination. Many people don't know what diseases uric acid is used to check?

What diseases does the uric acid test detect?

Uric acid testing is used to check for gout. Uric acid is produced by the oxidation of purine substances in the body. If the fasting blood uric acid levels are higher than normal twice on different days under a normal purine diet, hyperuricemia can be diagnosed. It may be caused by purine metabolism disorders or reduced uric acid excretion, or it may be caused by drinking alcohol or eating high-purine foods before the examination. Long-term high uric acid levels are harmful to the body. It is recommended that you avoid a high-purine diet, reduce or avoid the consumption of various broths, animal offal, various alcoholic beverages, seafood products, and meats that contain too much purine. At the same time, pay attention to drinking plenty of water. If uric acid is still high, you can choose uric acid-lowering drug treatment according to the situation.

What should I pay attention to in my diet before checking uric acid?

First of all, you must remember that you should strictly avoid eating a high-purine diet within 3-5 days before going to the hospital for examination, because purine food metabolites contain uric acid. Eating a large amount of high-purine food will cause a transient increase in uric acid, which may cause a temporarily high uric acid result. There are many foods high in purine: various meat products such as pork, beef, mutton, dog meat, poultry, etc. Secondly, animal offal is rich in purine, such as pig liver, pig kidney, pancreas, animal brain, etc. Again, various fish, shrimp, crab, shellfish and other seafood and soy products are also high-purine foods. In addition, common seasonings such as oyster sauce, abalone sauce, seafood sauce, mushroom sauce, etc. are also high-purine foods.

Second, before testing uric acid, you must eat less high-fat and high-calorie foods, because high-calorie foods may be converted into metabolites mainly composed of uric acid after metabolism, which will affect the test results and the judgment of the effectiveness of disease treatment. For example, various dried fruits, some foods rich in sugar, especially cream, cake, chocolate, etc.

Third, it is best not to drink alcohol within a week before the examination, especially beer, which has a very obvious boost to the formation of uric acid. In addition, do not drink coffee, strong tea, etc. within 3 days before the examination. These beverages themselves will not increase the purine content, but they have the effect of stimulating the autonomic nervous system. For people with high uric acid levels, they may induce an acute attack of gout.

Things to know about checking:

Before checking uric acid, you should also be careful to avoid strenuous exercise to avoid promoting the production of uric acid and causing the test results to be high.
