As a result of interfering factors, test results might be affected. When it comes to interference factors, it relies on the method adopted to analyze the same analyte. Hemolysis, lipemia, icterus, drugs, paraproteins, and other sample contaminants, such as gels, tube additives, and fibrin clots, are all examples of interference …
Calcium is required for efficient cellular function and signaling, as well as neuromuscular transmission, cardiac contractility, hormone secretion, and blood coagulation. Extracellular calcium concentrations are controlled within an extremely narrow range thanks to a number of feedback processes including parathyroid hormone (PTH) and the active vitamin D metabolite 1,25-dihydroxyvitmin D …
Thyroid tissue is made up of colloid, which includes iodinated thyroglobulin. Thyroglobulin is a big molecule that is synthesized by the surrounding follicular cells and from which thyroxine is produced and processed in colloid. Thyroid neuroendocrine cells (parafollicular or C cells) release calcitonin, a physiologically active peptide, and are situated …
