If the CV% between duplicate determinations of only one Marker  (IGF-I or P-III-NP) exceeds the respective u c_Max, the analysis of only that Marker shall be repeated;  − The mean Marker concentration from the duplicate measurement of IGF- I and P -III-NP shall be reported in ADAMS  in nanograms per milliliter (ng/mL);   [Comment: for the purposes of the Endocrine Module of the ABP, the GH -2000 score does not need to be calculated or reported by the Laboratory  since it will be automatically calculated in ADAMS 15].
