Biochemical research is highly reliable. Indicators of a biochemical blood test are used in all areas of medical practice, t. they reflect the functional state of almost all systems and organs.

Based on the results of biochemical analysis, the following indicators are determined:.

number of leukocytes, erythrocytes, platelets;

hemoglobin level;

leukocyte blood count;

erythrocyte sedimentation rate;

color indicator - displays the hemoglobin content in 1 erythrocyte;

percentage of red blood cells in a given volume of blood (hematocrit).

How to prepare for a biochemical blood test It is recommended to take blood for analysis on an empty stomach, from a vein. Before donating blood for a biochemical analysis, the patient should refrain from eating, drinking liquids for 6-12 hours before the procedure.. If a person is undergoing treatment, and constantly taking medications during the day, he should consult a doctor about this..

If the patient is shown to donate blood for a biochemical analysis more than once, for example, during treatment, to track the dynamics of the condition, he must know that it is desirable to do this at the same time: daily fluctuations, like the food consumed, affect the biochemical composition of the blood.

The result of the analysis is determined quickly - within one day. When using the express method, the indicators of a biochemical blood test can be determined within a few hours.

Biochemical blood test in childrenBlood in a child is taken mainly to determine the functionality of the kidneys and liver, so the standard biochemical blood test in children is designed to determine such indicators:.

total protein. Displays the level of globulin and albumin, characterizes the metabolism of proteins in the liver. Its normal level is 60-80 g/l;

AST and ALT. Marker enzymes that reflect existing liver disease. An increase in their level is observed with cholangitis, cirrhosis, infectious hepatitis, heat stroke.;

total bilirubin. Can be direct or indirect and reflects liver function;

urea. Displays the state of the excretory function of the kidneys, protein metabolism in the liver. The normal level of this indicator is 8.3 mmol / l. An increased level of urea in the biochemical analysis in children is observed with heart failure, burns, dehydration, stress, congestion in the urinary ducts, gastric bleeding;

creatinine. The indicator displays the work of the kidneys. Its norm is 0.0350 - 0.06 mmol / l. A decrease in creatinine is observed with a low-protein or high-carbohydrate diet, celiac disease (digestive disorder). Increased creatinine in renal failure, chronic and acute pyelonephritis, glomerulonephritis, kidney cyst and amyloidosis, metabolic pathologies.

Thymol test. This indicator is determined for the differential diagnosis of hepatitis A, B. Its indicator exceeds the norm in hepatitis A, but not in type B hepatitis.

A biochemical blood test in adults is different from a similar analysis in children.. The list of studied parameters in an adult is much longer. In addition, their characteristics and norms differ, which should be taken into account when deciphering the results.. In addition to those indicators that are determined by the analysis of the blood of children, the following are important for adult patients:.

cholesterol. Its norm is 3-6 mmol / l;

chlorine. An enzyme found in gastric juice and extracellular fluid that regulates the acid-base balance of the blood. Its norm for an adult is 98-107 mmol / l;

magnesium. Found in the liver, muscles, red blood cells. Its norm is 0.65-1.05 mmol / l;

alpha amylase. An elevated level of the indicator, detected using a biochemical blood test in adults, indicates pancreatitis, stones, tumors and cysts in the pancreatic ducts, renal failure, acute peritonitis, diabetes, parotitis, cholecystitis. The norm of this pancreatic amylase is 0-50 units / l; diastase - 28-100 units / l;

glucose. An important indicator of carbohydrate metabolism. The norm for an adult is 3.5-5.9 mmol / l; after 60 l - 6.38 mmol / l.
