Both during pregnancy planning and during pregnancy, a woman regularly undergoes a series of laboratory tests to assess her overall health and promptly identify any pathological changes.
A liver function test is a screening test aimed at assessing the functional state of the biliary system and liver. Diagnosis is made using a blood sample.
Lactate dehydrogenase isoenzymes are present in tissues in a strictly defined ratio, that is, each tissue, including blood, has a characteristic spectrum of lactate dehydrogenase isoenzymes unique to it.
Troponin I is a structural protein of the muscle troponin complex with a molecular weight of 26,500 Da. Troponins I, like troponins T, of cardiac and skeletal muscles differ significantly in their amino acid sequence.
The troponin complex is part of the muscle contractile system. It is formed by three proteins: troponin T, which binds to tropomyosin (molecular weight 3,700); troponin I (molecular weight 26,500), which can inhibit ATPase activity; and troponin C (molecular weight 18,000), which has a significant affinity for Ca2+.
Myoglobin is a heme-containing chromoprotein; it is a light chain of myosin with a molecular weight of 17.6 kDa. It is a protein that transports oxygen in skeletal muscle and myocardium.
Creatine kinase in cardiac muscle consists of two isoenzymes: CK-MM (60% of total activity) and CK-MB (40% of total activity). CK-MB is a dimer consisting of two subunits: M (muscle) and B (brain).
Creatine kinase reversibly catalyzes the phosphorylation of creatine. Creatine kinase is most abundant in skeletal muscle and cardiac muscle, while it is found in smaller amounts in the brain, thyroid gland, uterus, and lungs.
