Bhat N, et al. - Authors investigated if it was possible to truncate a combined simultaneous arginine clonidine stimulation test and intended to associate the outcome of the test with clinical indices of Growth Hormone (GH) status in individuals who underwent a combined simultaneous arginine clonidine stimulation test between January 1, 2007 and August 31, 2016. Data demonstrated that if the combined simultaneous arginine clonidine test were shortened to 120 min, 5.2% of normal responders would be missed. This test was not compared to any “gold standard” GH stimulation test. Nonetheless, a weak connection was discovered between the outcome of this test with clinical indices of GH status and spared patients the inconvenience of sequential testing.
