Six blood biochemical tests

Six tests of blood biochemistry are preliminary tests on human blood conditions, including 1, alanine aminotransferase, creatinine, urea nitrogen, serum glucose, triglycerides, and total cholesterol. Blood biochemical tests include blood urea (nitrogen) (BUN), creatinine (Cr), blood PH, sodium, potassium, chlorine, calcium, phosphorus, blood sugar, alkaline phosphatase, and the like. Blood urea and creatinine are urinary toxins. In fact, strictly speaking, these two are only a part of the toxin, because both are discharged by glomerular filtration and easy to monitor, so they have long been used to evaluate the main indicators of renal function. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: blood lipid analysis, blood biochemical full set, fasting blood glucose, liver function determination, etc. require fasting blood in the morning. Blood lipids are best measured in the first three days of blood. Animal blood, pig liver, iron, Chinese medicine and chloroplast-rich vegetarian food were fasted three days before the fecal occult blood test. Normal value Alanine aminotransferase (ALT): 35 IU/L0-45. Creatinine (CRE): 1.9 mg/dL 0.5-1.5. Urea nitrogen (BUN): 14.6 mg / Dl 6.0-23.0. Serum glucose (GLU): 223 mg/dL 60-110. Triglyceride (TG): 217 mg/dL 50-200. Total cholesterol (TCH): 179 mg/dL 150-220. Clinical significance Abnormal result Alanine aminotransferase (abbreviated as transaminase) is an indicator of impaired liver function. Transaminase is present in the mitochondria of liver cells. As long as the liver develops inflammation, necrosis, poisoning, etc., transaminase is released from the liver cells into the blood. Therefore, the disease of the liver itself can cause different degrees of elevated transaminase). Creatinine and urea nitrogen are an indicator of renal function (when renal dysfunction occurs, metabolic waste cannot be excluded from the body, so that a large amount of nitrogenous wastes and other toxic substances accumulate in the body, and the homeostasis is destroyed). Serum glucose is an indicator of blood glucose concentration in the blood and is important for diagnosis and guidance in the treatment of diabetes. Triglyceride and total cholesterol are an indicator of blood lipid levels in the blood. Blood lipids are a general term for various lipids in the blood, the most important of which are cholesterol and triglycerides. Whether it is elevated in cholesterol or triglyceride Increased, or both increased, are collectively referred to as hyperlipidemia, hyperlipidemia and coronary heart disease have a close relationship, especially those with elevated cholesterol and triglycerides, the risk of coronary heart disease is greater). The people who need to be examined are people with heart palpitations, fatigue, sweating, hunger, paleness, tremors, nausea and vomiting. People with edema, increased foam in the urine, hematuria, pain in the lower back, and symptoms of high blood pressure. Precautions Inappropriate people: People who have obvious bleeding tendency or take medicine and eat foods that affect testing. Taboo before inspection: 1, blood lipid analysis, blood biochemical full set, fasting blood glucose, liver function determination, etc. require fasting blood in the morning. 2, blood lipid determination is best three days before the blood test vegetarian. 3, fasting animal blood three days before the fecal occult blood test, pig liver, iron, Chinese medicine and rich in leafy green vegetarian food. 4, bacterial culture specimens, must use a sterilization container, take clean urine for inspection. 5, sputum specimens bacterial culture, it is best to gargle in the morning, cough up the first sputum (from the lungs) for inspection. 6, endocrine hormones, blood sampling time should be carried out according to doctor's advice. Requirements for examination: When taking blood, you should relax your mind to avoid the contraction of blood vessels caused by fear and increase the difficulty of blood collection. Inspection process Immediately after venous blood collection, the test is performed. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
