In the laboratory, maintaining sterility is essential to ensuring the accuracy and reliability of all analytical results. To support this, Lab Analyst Jarisha Binion performs Quality Control (QC) testing on soy broth—a nutrient medium used to verify the sterility of sample bottles and sterile water prepared for laboratory use.
Before being used, each batch of soy broth undergoes thorough QC testing to confirm that it behaves as expected: it should support microbial growth when contaminated and remain clear when sterile. Once verified, the broth is used to test sample bottles and sterile water for any possible contamination. These materials are incubated for 24 and 48 hours, during which Jarisha carefully monitors them for any signs of microbial growth.
If no growth is observed after the incubation periods, the bottles and water are confirmed sterile and ready for use in laboratory testing. This meticulous process ensures that all lab supplies meet stringent quality standards, safeguarding the integrity of analytical results and maintaining compliance with laboratory best practices.
