Biochemical analysis of blood

Биохимический анализ кровиThe biochemical research differs in high reliability. Indicators of biochemical analysis of blood use in all fields of medical practice since they display a functional condition practically of all systems and bodies.

By results of biochemical analysis define the following indicators:

  • quantity of leukocytes, erythrocytes, thrombocytes;
  • hemoglobin level;
  • leukocytic blood count;
  • blood sedimentation rate;
  • the color indicator – displays a hemoglobin content in 1 erythrocyte;
  • percentage indicator of maintenance of erythrocytes in a certain volume of blood (hematocrit)

How to be prepared for delivery of biochemical analysis of blood

Recommend to take blood for the analysis on an empty stomach, from a vein. Before taking a blood test on biochemical analysis the patient has to abstain from meal, liquid for 6-12 hours prior to a procedure. If the person undergoes treatment, and constantly within a day accepts medicines, he in this respect should consult with the doctor.

Биохимический анализ крови у взрослыхIf to the patient is shown to take a blood test on biochemical analysis not once, for example, during treatment, for tracking of dynamics of a state, he has to know that it is desirable to do it in identical time: daily fluctuations as well as the eaten food influence biochemical composition of blood.

The result of the analysis is defined quickly – within one day. When using an express method indicators of biochemical analysis of blood can are defined within several hours.

Biochemical analysis of blood at children

Blood from the child is taken generally for definition of functionality of kidneys and a liver therefore standard biochemical analysis of blood at children is intended for definition of such indicators:

  • crude protein. Displays the level of globulin and albumine, characterizes exchange of proteins in a liver. Its normal level – 60-80 g/l;
  • Nuclear heating plant and ALT. The enzymes markers displaying the available liver diseases. Increase in their level is observed at a cholangitis, cirrhosis, infectious hepatitis, heatstroke;
  • general bilirubin. Can be direct and indirect and displays functionality of a liver;
  • urea. Displays a condition of secretory function of kidneys, exchange of proteins in a liver. Normal level of this indicator – 8,3mmol/l. The increased urea level in biochemical analysis at children is observed at heart failure, burns, dehydration, a stress, stagnation in urinary channels, gastric bleeding;
  • creatinine. The indicator displays work of kidneys. Its norm – 0,0350 - 0,06mmol/l. Decrease in creatinine is observed at a reduced-protein or high-carbohydrate diet, a Gee's disease (digestion disturbance). Creatinine at a renal failure, chronic and acute pyelonephritis, a glomerulonephritis, a cyst of kidneys and an amyloidosis, metabolism pathologies raises.
  • Thymol turbidity test. This indicator is defined for differential diagnosis of hepatitis A, B. Its indicator exceeds norm at hepatitis A, and at hepatitis of V type – no.

Biochemical analysis of blood at adults differs from the similar analysis at children. The list of the studied indicators at the adult much more. Besides their characteristic and norms differ that should be considered at interpretation of results. Except those indicators that are defined at blood test of children, for adult patients the following matters:

  • cholesterol. Its norm – 3-6¼¼«½ý/l;
  • chlorine. The enzyme which is contained in a gastric juice and extracellular liquid and regulating acid-base balance of blood. Its norm for the adult – 98-107¼¼«½ý/l;
  • magnesium. Contains in a liver, muscles, erythrocytes. Its norm – 0,65-1,05¼¼«½ý/l;
  • alpha amylase. The increased indicator level revealed by means of biochemical analysis of blood at adults indicates pancreatitis, stones, tumors and cysts in channels of a pancreas, a renal failure, acute peritonitis, diabetes, parotitis, cholecystitis. Norm of it amylases pancreatic – 0-50Ññ/l; diastases – 28-100Ññ/l;
  • glucose. Important indicator of exchange of carbohydrates. Norm for the adult – 3,5-5,9 mmol/l; after 60 l – 6,38 mmol/l.
