Figure 1 is a histogram showing the number of stool tests performed per month by laboratory between 2010 and 2014. A line shows the total rate of stool tests per 100 000 population. While the number of tests performed at the public laboratory does not noticeably increase after 2013 when culture independent diagnostic testing was introduced, the number of tests at both private laboratories increased noticeably. The rate of tests per 100 000 also increased after 2013.
