What is a biochemical test?
Biochemical examination is a laboratory testing method commonly used in clinical medicine. By analyzing biochemical indicators in body fluids such as blood and urine, it helps doctors evaluate the patient's health status, diagnose diseases, or monitor treatment effects. Below we will introduce biochemical examinations in detail in terms of definitions, common items, clinical applications, etc.
1. Definition of biochemical examination
The full name of biochemical examination is "biochemical examination". It is a laboratory examination method that reflects organ function, metabolic status and disease conditions by detecting chemical components (such as enzymes, proteins, sugars, lipids, electrolytes, etc.) in human body fluids (such as blood, urine). It is an important tool for modern medical diagnosis and health management.
2. Common biochemical examination items
| Project Category | Specific indicators | clinical significance |
|---|---|---|
| liver function | ALT, AST, ALP, total protein, albumin, bilirubin | Assess liver metabolism and detoxification function |
| kidney function | Creatinine, urea nitrogen, uric acid | Reflects the excretory function of the kidneys |
| blood lipids | Total cholesterol, triglycerides, HDL, LDL | Assess cardiovascular disease risk |
| blood sugar | Fasting blood glucose, glycosylated hemoglobin | Diagnose diabetes and monitor blood sugar control |
| electrolyte | Potassium, sodium, chloride, calcium | Assess body water and electrolyte balance |
3. Clinical application of biochemical examinations
1.disease diagnosis: For example, hepatitis is diagnosed through abnormal liver function, and diabetes is diagnosed through elevated blood sugar.
2.health screening: Potential health problems are discovered through biochemical indicators during routine physical examinations.
3.Efficacy monitoring: For example, diabetic patients regularly test their blood sugar to evaluate the effect of treatment.
4.Preoperative evaluation: Evaluate the functional status of the patient's organs through biochemical examinations before surgery.
4. Precautions for biochemical examination
| Things to note | Description |
|---|---|
| fasting requirement | Most projects require 8-12 hours of fasting to avoid diet affecting the results. |
| Blood collection time | It is recommended to collect blood between 8 and 10 a.m. to comply with the circadian rhythm. |
| drug effects | Some drugs may interfere with the results, so you need to inform your doctor in advance |
| Sports effects | It is not advisable to check immediately after strenuous exercise |
| Interpretation of results | Comprehensive judgment should be made based on clinical symptoms and other examinations |
5. Development Trend of Biochemical Examination
1.Detection technology: From traditional biochemical analyzers to fully automated and intelligent detection systems.
2.Test items: Expanding from conventional indicators to more specific biomarkers.
3.Detection speed: Emergency biochemistry projects can produce results within 30 minutes.
4.precision medicine: Combined with genetic testing to achieve personalized medicine.
6. Recent hot topics related to biochemical examinations
| hot topics | Summary of contents |
