A clinical microbiology laboratory compared the frequency of isolation of DNA hybridization probe to a culture method for the sexually transmitted bacterium Neisseria gonorrhaeae. The frequency of isolation from clinical specimens was historically 10%. The lab ran 100 split samples, and the results are presented in the table below.
