Table 3: Codes determined for several different drugs using an in-house designed macro to measure individual changes in Red, Green, and Blue values. The hyphenated code is assembled beginning with Red Green Blue values for DC1 in buffer A – Red Green Blue values for DC1 in buffer B–Red Green Blue values for DC2 in buffer A–etc. N represents the number of total codes determined and the percentage error represents the total deviations from any of the 48 digits of this determined code.
