Biochemistry is a laboratory test performed to diagnose diseases in a clinical setting. Biochemistry is the abbreviation of biochemistry, which is a laboratory test to study the composition of the body’s organs and cells, such as the value or content of proteins, sugars, lipids, nucleic acids and other substances, to help determine the extent of the disease’s impact on the body. A complete set of biochemical tests includes a combination of liver function, kidney function, blood glucose, lipids, and cardiac enzyme profile. If the patient’s condition is serious or involves multiple organs, a complete set of biochemical tests can provide a comprehensive assessment of whether the function of important organs is normal and, if so, to what extent, and thus provide a clinically reliable basis for diagnosis, assessment and prognosis of the disease. A complete set of biochemical tests must be performed by fasting blood to ensure the accuracy of the results, and the doctor will make a comprehensive analysis and judgment based on the test results. Therefore, if there is a single abnormality in the complete set of biochemical test results, the patient should not worry too much, patiently consult the doctor in charge to clarify the cause of the abnormality, and then target intervention or conditioning, and wait until the symptoms are relieved to review one of the items, such as liver function, kidney function, etc. It is not necessary to review the complete set. However, if the condition requires, a full set of biochemical reexamination should be performed to comprehensively assess the effect of treatment and promote prognosis and recovery.
