blood chemistry

 blood chemistry
 Biochemical features high reliability. Indicators of biochemical analysis of blood used in all areas of medical practice, because they reflect the functional state of practically all organs and systems.

According to the results of biochemical analysis, the following indicators:

  • the number of leukocytes, erythrocytes, thrombocytes;
  • hemoglobin level;
  • WBC blood;
  • erythrocyte sedimentation rate;
  • color indicator - displays the content of hemoglobin in the red blood cell 1;
  • percentage content of red blood cells in a defined volume of blood (hematocrit)

How to prepare for the biochemical analysis of blood

Take blood for analysis recommended fasting from a vein. Before you donate blood for the biochemical analysis of the patient should refrain from eating, drinking for 6-12 hours before the procedure. If the person being treated, and constantly during the day takes drugs, he in this respect should consult a doctor.

 Biochemical analysis of blood in adults
 If the patient is shown to give blood for biochemical analysis more than once, for example, during treatment, to monitor the dynamics of the state, he must know what to do it is desirable in the same time as the daily fluctuations in food and drink affect the biochemical composition of the blood.

The result of the analysis is determined quickly - within a day. When using a rapid method of biochemical analysis of blood parameters can be determined within a few hours.

Biochemical analysis of blood of children

The blood of a child takes primarily to determine the functionality of the kidneys and the liver, so the standard biochemical analysis of the blood of children is designed to determine such indicators:

  • total protein. It displays the globulin and albumin, characterizes the metabolism of proteins in the liver. Its normal level - 60-80 g / l;
  • AST and ALT. Enzymes markers displaying available liver disease. Increase their level observed in cholangitis, cirrhosis, infectious hepatitis, heatstroke;
  • total bilirubin. It may be direct or indirect and shows the functionality of the liver;
  • urea. It displays the status of renal excretory function, the metabolism of proteins in the liver. The normal level of this indicator - 8 3mmol / l. Elevated levels of urea in the biochemical analysis of children observed in heart failure, burns, dehydration, stress, stagnation in the urinary duct, stomach bleeding;
  • creatinine. The indicator displays the work of the kidneys. Its rate - 0, 0350 - 0, 06mmol / L. Reduced creatinine observed at low protein or high-carbohydrate diet, celiac disease (indigestion). Increased creatinine in patients with renal insufficiency, chronic and acute pyelonephritis, glomerulonephritis, renal cysts, and amyloidosis, metabolic pathologies.
  • Thymol test. This indicator measures the differential diagnosis of hepatitis A and B. Its rate exceeds the rate of hepatitis A and hepatitis B-type - no.

Biochemical analysis of blood of adults is different from such an analysis in children. The list of the parameters studied in the adult much more. In addition, their characteristics and standards are different, which should be considered when interpreting the results. In addition to those indicators that are defined in the analysis of the blood of children, adult patients have a value as follows:

  • cholesterol. Its rate - 3-6mmol / l;
  •   chloro. The enzyme contained in gastric juice and extracellular fluid and regulates the acid-base balance of the blood. His norm for an adult - 98-107mmol / l;
  • magnesium. Contained in the liver, muscles, erythrocytes. Its rate - 0, 65-1, 05mmol / L;
  • alpha-amylase. Elevated levels of indicators identified by a biochemical analysis of the blood of adults, indicating pancreatitis, stones, tumors and cysts in the ducts of the pancreas cancer, renal failure, acute peritonitis, diabetes, mumps, cholecystitis. The rate of pancreatic amylase - 0-50ed / l; diastase - 28-100ed / l;
  • glucose. An important indicator of the metabolism of carbohydrates. Normal adult - 3, 5-5, 9 mmol / l; 60l after - 6, 38 mmol / l.
