The Wellcolex Color Shigella rapid latex test can be used directly on primary plate colonies on Day 2 of testing.
Since most stool samples tested for Shigella are negative, negative results on Day 2 of testing eliminates the need for further testing. In addition, multiple colonies can be pooled and screened in a single reaction, reducing multiple testing and associated cost.
The test incorporates red and blue latex particles sensitized with antibodies to different Shigella species, giving species identification in a single test. Its Negative Predictive Value is 99.9 percent, and its Positive Predictive Value is 98.7 percent.
