Introduction
For routine health checkups or general disease screening, the three basic biochemical tests typically focus on fundamental metabolic indicators, such as alanine aminotransferase (ALT) for liver function, creatinine for kidney function, and fasting blood glucose. These markers can preliminarily reflect liver metabolism, kidney excretory function, and blood glucose regulation, helping to assess overall baseline health and detect early metabolic abnormalities.
Generally, a basic three-item biochemical panel typically includes fundamental indicators such as liver function, kidney function, and blood glucose levels, although specific tests may vary depending on the purpose of the examination. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed analysis is as follows:
If the test is for routine health screening or general disease detection, the three-item biochemical panel usually focuses on core metabolic markers, such as alanine aminotransferase (ALT) for liver function, creatinine for kidney function, and fasting blood glucose. These indicators provide an initial assessment of liver metabolism, kidney excretion function, and blood glucose regulation, helping evaluate overall health and detect early metabolic abnormalities.
If the test aims at screening for specific conditions or monitoring during pregnancy or post-surgery, the three-item panel may be adjusted to target specific markers. For example, during pregnancy, progesterone, human chorionic gonadotropin (HCG), and estradiol might be tested; after surgery, electrolytes, protein levels, and inflammation-related markers may be monitored. Such adjustments are made according to clinical needs to more accurately assess specific physiological or pathological states and support diagnosis and treatment decisions.
Prior to undergoing a three-item biochemical test, proper preparation is required, such as fasting and avoiding strenuous exercise. Results should be interpreted by a physician in conjunction with clinical symptoms. If any abnormalities are detected, further evaluation or lifestyle modifications should be pursued under medical guidance—do not self-interpret the results.
