For the quantitative determination of Growth Hormone (GH) in human serum. For in vitro diagnostic use in the United States. For Research Use Only outside of the United States. Intended to be used manually but may be adaptable to open automated analyzers. The user is responsible for validating the performance of this kit with any automated analyzers.
Human growth hormone (GH) is a polypeptide of 191 amino acids secreted by the somatroph cells of the anterior pituitary. Growth hormone is principally a regulator of body growth and its metabolic effects are primarily anabolic. Some of its effects include promotion of protein conservation through its involvement in a wide range of protein synthesis mechanisms, enhancement of glucose transport and facilitation of glycogen storage. In addition, it induces the release of somatomedins (insulin-like growth factors), which further mediate the cascade of growth promoting actions. Measurement of GH is primarily of interest in the diagnosis and treatment of various forms of decreased secretion of GH. Hyposecretion of GH in children results in growth retardation and hypersecretion leads to gigantism in children and acromegaly in adults. The secretion of GH varies throughout the day under the influence of intricate neurogenic, metabolic and hormonal control. Due to the pulsatile nature of GH release, it is often inaccurate to define a reference range and status based on single serum measurements. To diagnose disorders of GH secretion more reliably, dynamic tests are used in which serum GH levels are measured over a period following suppression or stimulation of GH secretion.
1. What percentage of your IgE allergy testing panel consists of molecular allergens rather than allergen extracts? The ALEX2 IgE allergen panel consists of 117 extracts and 183 molecular allergens. This represents the largest panel of molecular allergens on the market, including 50 unique...
Cases of food and environmental allergies have been increasing over the last decade. While conservative estimates suggest IgE-mediated allergy affects 6-8% of children and 2-3% of adults, some estimates are as high as 30%.3, 2 Symptoms can range from mild to severe and include itching, hives,...
Food sensitivity or food intolerance involves a non-allergic response to a food or food additive. In a recent on-line survey conducted in the U.S., 24% of adults aged 18 to 79 reported a food intolerance. While a food allergy is typically mediated by IgE antibodies, adverse reactions to food...
In a head-to-head comparison of FDA-cleared assays and a novel ALPCO method, investigators observed wide variability in specificity and false-positive rates across platforms, raising important questions about standardization and clinical interpretation.
