The whole body wasting type refers to the human body weight loss due to disease or some factors, below the standard weight of 10% or more is wasting (some authors believe that where the weight is more than 10% lower than the standard weight is thin, less than 20% or more is called wasting). What tests are needed for generalized wasting? 1.Maximum gastric acid secretion measurement (MAO): After stimulated by pentagastrin, the amount of gastric acid that can be secreted by the lining cells after 1 hour to fully play its secretory function is called MAO. 2.Free triiodothyronine (FT3): T3 is a hormone synthesized and secreted by the thyroid follicular cells. FT3 accounts for about 0.3% of T3 and can enter the tissue cells through the cell membrane to play physiological effects. Its concentration is consistent with the concentration of triiodothyronine in tissues and with the metabolic state of the body, and is also of diagnostic value for non-thyroidal diseases. The RIA method is commonly used in clinical practice. 3.Plasma thyrotropin-releasing hormone (TRH): plasma thyrotropin-releasing hormone (TRH) is an indicator to detect hypothalamic function. 4.Gastric free hydrochloric acid measurement: free acid is hydrochloric acid, and bound acid refers to hydrochloric acid that is loosely bound to protein. 5, gastric basic gastric acid secretion measurement (BAO): basic gastric acid secretion (BAO) refers to the amount of gastric acid secretion in the absence of food and drug stimulation for a continuous period of time. 6.Pepsin measurement: The predecessor of pepsin is pepsinogen, which is secreted by the main cells of the fundic glands and converted into pepsin in gastric acid. Measurement of pepsin helps to diagnose gastric diseases.
