Biochemical blood test – a method of blood testing, often used in therapy, rheumatology, gastroenterology, and other fields of medicine. It is this laboratory analysis that most accurately reflects the health of systems and organs.
Glucose in the blood biochemistry
About a day after you have donated blood, get the results of biochemistry. They indicate the amount of the contents of various substances. It is quite difficult for a person without medical education to independently understand the results of the analysis. But today the interpretation of the analysis of blood biochemistry is always attached in the medical institutions.
The sugar content in the blood is the index of carbohydrate metabolism. In the norm of glucose should not be more than 5.5 mmol / l and not less than 3.5 mmol / l. A steady increase in this indicator is most commonly observed when:
- Cushing’s syndrome;
- permanent excessive physical exertion;
- Diseases of the endocrine glands.
If you have a lower glucose level The general biochemistry of the blood, the decoding will indicate that you have an insulin overdose, a deficiency in the function of the endocrine glands, or severe poisoning that is accompanied by liver damage.
Pigments in the biochemistry of the blood
In deciphering the blood test for biochemistry the amount of pigments – bilirubin direct and bilirubin total – is given. The standard of total bilirubin is 5-20 μmol / l. A strong change in this indicator is characteristic of various liver diseases (for example, hepatitis and cirrhosis), mechanical jaundice, poisoning, liver cancer, cholelithiasis, and vitamin B12 deficiency.
The norm of direct bilirubin is 0-3.4 μmol/l. If you have blood biochemistry and this indicator is higher, the decryption may indicate that you have the following:
- toxic or acute viral hepatitis;
- infectious liver disease;
Fats in biochemical blood analysis
If there is a violation of lipid metabolism in the blood, the content of lipids and/or their fractions (cholesterol esters and triglycerides) is increased. The interpretation of these indicators in the results of blood biochemistry assays is very important as they are very important for a correct assessment of the functional ability of the kidney and liver in a variety of diseases. Normally it should be:
- Total cholesterol – 3.0-6.0 mmol / l;
- Triglycerides 0.40-2.70 mmol / l (depending on age).
Water and mineral salts in blood biochemistry
There are several inorganic substances: potassium, folic acid, iron, calcium, magnesium, phosphorus, sodium, chlorine. Injuries of water-mineral metabolism of any kind are very commonly observed in severe and mild forms of diabetes mellitus, cirrhosis and heart problems.
Normally, the potassium level should be within 3.5-5.5 mmol / l. If there is an increase in its concentration, then the biochemistry of blood for women and men declares that this is hyperkalemia. This condition is characteristic of hemolysis, acute renal failure, dehydration, and adrenal insufficiency. A strong decrease in potassium content means Hypokalemia. This condition is a sign of impaired renal function, cystic fibrosis, an excess of hormones in the adrenal cortex.
In the analysis of blood biochemistry, the sodium standard is 136-145 mmol / l. An increase in this indicator usually indicates a violation of the function of the adrenal cortex or the pathology of the hypothalamus.
Normally chlorine in the blood ranges from 98-107 mmol/l. If the indicators are larger, the person may have dehydration, salicylate poisoning, or adrenocortical dysfunction. However, the decrease in chloride content is observed with vomiting, a significant increase in fluid volume, and excessive sweating.
