6.0 Analytical Testing Procedure and Reporting of Test Results  6.1 Initial Quantification of the Markers  − One (1) Aliquot  taken from  the original “A” Sample  shall be analyzed once (x1) to quantify  T and A4;  − QC Sample(s), at low - and high- levels of the Marker s (see Table 1), shall be included in each initial quantification analytical batch;  − The T and A4 Marker  concentrations shall be reported in ADAMS in nanograms per milliliter (ng/mL) ; [Comment: for the purposes of the Steroidal Module of the ABP, the T/A4 ratio does not need to be c alculated or reported by the Laboratory ; it will be automatically calculated in ADAMS].
