Biochemical tests are a type of blood test. The indicators of blood tests mainly include total bilirubin, indirect bilirubin, glutamic-oxaloacetic transaminase, and alanine aminotransferase, as well as renal function indicators such as blood creatinine and blood urea nitrogen.

Biochemical tests mainly focus on kidney function, liver function, and blood sugar levels. Through this test, it can accurately determine whether the patient has kidney disease, liver disease, or hyperglycemia. If there are abnormalities in kidney, liver, and blood sugar levels, these indicators will also show abnormalities. By analyzing the test results, it can be determined what diseases the patient has. After that, by actively cooperating with the treatment under the doctor’s guidance, the condition can be alleviated. The human body is inherently fragile, and the body’s resistance is also weak. If treatment is not sought promptly after falling ill, the condition may worsen further, and severe cases may lead to a series of complications.

Before undergoing biochemical tests, if the patient smokes, it will not affect the test results. However, it is important to note that no food should be consumed within 8 hours before the biochemical test. If food is eaten before undergoing the biochemical test, it may result in inaccurate test results. In addition, it is also necessary to avoid excessive drinking, staying up late, and overworking before the test. Especially, women are best not to undergo biochemical tests during their menstrual period to avoid affecting the test results.
