What Is the Workflow of Nucleic Acid Extraction Instrument and What Are the Precautions?

　　Author：MeCan Medical–ultrasound machine manufacturersThe fully automated biochemical analyzer is used for conventional health inspection and disease screening experiments. Through a full set of biochemical inspections, it understands its own health status. Due to its fast measurement speed, small reagent consumption and high accuracy, it has been widely used in units at all levels. In the biochemical inspection, in order to ensure the accuracy of the test results, what problems should we pay attention to before sampling?Avoid tension and emotional excitement: Otherwise, it can affect God's endocrine function, affect breathing, and increase lactic acid.Avoid strenuous exercise: Generally, it is advisable to do not do severe exercise within 24 hours before blood drawing. Blood is collected in the early morning. Inpatient patients can take blood before getting up. Patients who rushed to the outpatient clinic should take at least 15 minutes and take blood to take blood. Strong muscle exercise significantly affects the metabolism in the body, causing changes in certain component concentrations in the blood, such as lactic acid, creatine kinase (CK), citizen amin aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphate, alkaline phosphate Enzyme (ALP), glucose (GLU), etc.Avoid drinking before blood: drinking before taking blood can increase blood lactic acid, uric acid, etc. quickly, and continuous drinking can see AST, Alanine transaminase (ALT), -glutamyl metastases (-GT), and -GT rise up obvious. Those with long-term alcohol often have triglycerides, and -GT will also be abnormal for a long time.Pay attention to a reasonable diet: In addition to emergency or other special reasons, it is generally advocated that after 12 hours of fasting for 12 hours, blood takes blood on an empty stomach, extending the empty time (hunger) or the chemical composition of blood after meals will cause changes. For example, blood sugar and protein are reduced, and bilirubin increases; postprandial blood glucose, potassium, alkaline phosphatase and triglyceride are usually increased, inorganic phosphorus decreases, and serum can be turbid. In addition, the amount of diet and quality also affects the test results. For example, a high -protein diet can increase serum urea, blood ammonia, uric acid; high -fat diet cause chlorophytic sepsis and cause serum turbid Or concentrated; beverages containing caffeine can release catecholamine. The blood components are affected by the diet. The ingredients with large variables include potassium ions (K), GLU, total cholesterol (TC), triglyceride (TG), inorganic phosphorus (IP), etc.Avoid the impact of drugs: Many drugs (hormones, hypoglycemic drugs, diuretic drugs, antiepileptic drugs, anticancer drugs, etc.) can increase or decrease some test items after entering the human body. Pay attention to the history of medication when analyzing and judging the results.The impact of the position when taking blood: change (standing, sitting, and lying position) changes can cause significant changes in certain testing indicators. Therefore, it is recommended to take blood for 5 minutes when taking blood.
