Dynamic test for suspected growth hormone (GH) deficiency. It should be noted that non-pituitary disorders, including hypothyroidism, adrenal insufficiency, obesity and malnutrition, may reduce GH response to physiological and pharmacological stimuli. Clonidine, an alpha-adrenergic drug, stimulates GH release. Severe arterial hypotension can occur following clonidine administration. This tends to be self-limiting and will resolve after a variable period (up to several hours) if the child is left lying down. No child should be allowed to leave the ward for at least three hours after giving the drug. Generally used as a second-line test in subjects showing a subnormal GH response in a previous screening test (exercise, sleep or Bovril stimulation). Give clonidine hydrochloride orally (150 g/m2 body surface area). Collect the following samples: If the response is subnormal it is usual to proceed to an insulin sensitivity test before firmly making the diagnosis of GH deficiency. buy viagra at tesco online Blood samples are taken through an intravenous (IV) line instead of reinserting the needle each time. The procedure is done the following way: DO NOT eat for 10 to 12 hours before the test. If your child will have this test, explain how the test will feel. The more familiar your child is with what will happen and the purpose of the procedure, the less anxiety he or she will feel. In some laboratories, the normal level is 7 ng/m L (7 µg/L). Ask your provider if you should stop taking any of your medicines before the test. When the needle is inserted to draw blood, some people feel moderate pain. Afterward, there may be some throbbing or a slight bruise. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results. Kaneshiro, MD, MHA, Clinical Professor of Pediatrics, University of Washington School of Medicine, Seattle, WA.

Nair Road, Mumbai Central, Mumbai, Maharashtra India Source of Support: None, Conflict of Interest: None Context: To find a single time point during clonidine stimulation test (CST), with highest diagnostic value to rule out growth hormone deficiency (GHD). Settings and Design: This is a retrospective study of 79 CSTs carried out in a tertiary care center in India. Materials and Methods: A cohort of 79 children with unexplained short stature was divided into two groups: GHD and non-GHD. Any one stimulated growth hormone (GH) level 10 ng/m L was used to rule out GHD. Diagnostic accuracy of not only single time points but also time points in pairs was calculated. Statistical Analysis: The data were analyzed using SPSS statistical software 22.0. Descriptive statistics were used for analyzing demographic data. Growth hormone (GH) is a protein produced by the pituitary gland. For most people, GH levels naturally rise and fall during childhood and then are lower in adulthood. In some people, however, GH levels can be lower than normal. A persistent shortage of GH is known as growth hormone deficiency (GHD). The condition can cause health problems such as decreased muscle mass and slow growth. If your doctor suspects that your body is not producing enough GH, they may order a GH stimulation test. Testing is usually only done when there is strong evidence that a person has this condition. In children, GHD may include symptoms such as below average height, slow growth, poor muscle development, and delayed onset of puberty. In adults, the symptoms of GHD are somewhat different because adults have stopped growing.
