ARG plus GHRH test, high sensitivity (96 and 95%, respectively) and specificity (92 and 91%, respectively) for GH deficiency were achieved
-
The greatest diagnostic accuracy occurred with the ITT and the ARG plus GHRH test
-
95% specificity could be achieved with the ARG plus L-DOPA and ARG tests only with very low peak GH cut-points (0.25 and 0.21 microg/liter, respectively) and not at all with the L-DOPA test

study evaluated 6 tests for HGH deficiency diagnosis. Ninety-five percent specificity found with ARG + l-DOPA and ARG alone. However, the authors found a 95% specificity with IGF-1 < 77. Although, IGF-1 is false negative in up to 65% of those with HGH deficiency.
