Example of A Good Sample

There are three cell swab samples in this picture (left-click to enlarge).
The top two are "good" samples. Enough cells are in the center area of the collection swab to accurately analyze the DNA. This is represented by the white discoloration on the pad.
The example on the bottom is a sample of a swab with insufficient cells collected. There are not enough cells for accurate analysis.
Please make sure an adequate quantity of cells has been collected within the circular area on the collection swab.
