List Analyzes – B
The causative agents of brucellosis are brucellae, small immobile gram-negative bacteria. When diagnosing brucellosis, the obtained clinical and epidemiological data should be confirmed laboratory.
Disturbance of the metabolism of phenylalanine refers to a very common congenital metabolic disorder. Due to the defect of the phenylalanine hydroxylase gene (phage gene), the enzyme deficiency develops, and as a result, the block enters the normal conversion of phenylalanine to the amino acid tyrosine.
Galactosemia is based on the inadequacy of galactose-1-phosphate uridyltransferase (classical galactosemia) or, more rarely, galactokinase or galactose-epimerase.
A blood test is the most common method of research, without which modern diagnostics are not possible. Different types and methods of analytical blood research help modern medicine to quickly and accurately identify hundreds of thousands of ailments.
Parathyroid hormone - a polypeptide consisting of 84 amino acid residues, is formed and secreted by parathyroid glands in the form of high-molecular prohormone. Progormone after exiting the cells undergoes proteolysis with the formation of parathyroid hormone.
The beginning of blood coagulation in a healthy person is from 30 seconds to 2 minutes, the end from 3 to 5 minutes. Blood is taken from the finger into a clean and dry capillary from the apparatus of Panchenkov.
Blood albumin is a very important protein component of human blood. The name comes from the Latin word - white (albus). It is a protein that is highly soluble in salty and acidic media, and, moreover, the protein is almost pure, as it does not contain a single milligram of carbohydrates.
Normally, bilirubin in the urine is not determined, since unconjugated bilirubin is insoluble in administration and is not secreted by the kidneys. Obstruction of extrahepatic biliary tract serves as a classic cause of bilirubinuria.
Beta-chorionic gonadotropin is a glycoprotein secreted by the syncytial layer of trophoblast during pregnancy. It supports the activity and existence of the yellow body, stimulates the development of the embryoblast. Excreted in the urine.
Chorionic gonadotropin - a hormone consisting of 2 subunits - alpha and beta, non-covalently connected to each other; the alpha subunit is identical to the alpha subunit of LH, FSH and TSH, the beta subunit is specific for chorionic gonadotropin.
Beta2-microglobulin is a low-molecular protein of surface antigens of cell nuclei. Its presence in the blood serum is due to the processes of degradation and repair of individual cell elements.
Basophils are blood cells that contain coarse purple-blue granules in their cytoplasm. The main component of the basophil granules is histamine.
Bacteriuria is the detection of bacteria in the urine. Bacteriologic examination of urine yields minimal clinical information for the diagnosis of urinary tract infections, so culture methods are used.
B-lymphocytes carrying IgM, - cells of humoral immunity, responsible for the synthesis of antibodies. They are formed in the red bone marrow and accumulate mainly in the peripheral lymphoid organs. Peripheral blood contains only 3-10% of their total number.
B-lymphocytes carrying IgG, - cells of humoral immunity, responsible for the synthesis of antibodies. They are formed in the red bone marrow and accumulate mainly in the peripheral lymphoid organs. Peripheral blood contains only 2-6% of their total number.
B-lymphocytes are heterogeneous in their population and perform various functions, the main one of which is Ig secretion. Mature B lymphocytes express Ig on the cell membrane. Such membrane Ig functions as antigen-specific receptors and are the most important markers of B-lymphocytes.
