The volume/weight of sample and total volume of the extract can be modified to suit the sample.  This will ultimately be dictated by the amount of analyte of interest in the sample and may require empirical determination.  For low levels of analyte the sample:extract volume ratio can be increased (i.e. increase the sample and/or decrease the total extraction volume).

Alternatively, for samples with low concentrations of analyte, a larger sample volume can be added to the kit assay. When altering the sample volume adjust the distilled water volume added to the assay accordingly so that the total assay volume is not altered.
