| Preparation Note: | Description• This PT sample is designed for the quantitative analysis of fecal streptococcus. • The PT sample is provided as a stable disc requiring hydration. • The PT sample is provided in duplicate as a stable dehydrated disc requiring hydration. The additional sample is provided for mishaps in the lab. This sample requires 100 ml of buffer/ saline solution for hydration fluid (see note below). The dehydrated disc sample is stable for a time exceeding the study schedule. • If you are following IDEXX methods for Quantitray do not use the phosphate buffer solution and follow the directions provided with the media. • When prepared according to instructions, the concentration range of the sample will be between 20-1000 CFU/100mL as per TNI Fields of Testing.. Sample Preparation• Allow the capped sample vial to equilibrate to room temperature (15 min). • Once the sample is at room temperature and open the sample vial and aseptically transfer the disc to the hydrating fluid. Allow it to dissolve for 15 minutes. Shake gently. Note: The sample is the colored disc within the cryotube. It will either be on top of cotton with opaque desiccant beads below the cotton or free moving in a cryotube that contains a desiccant tablet within the cap. The opaque desiccant beads and desiccant tablet are to keep the container dry and are not biologicals. • This dilution is your sample for analysis. Note: The Vitroid™ is the colored disk within the cryotube. It will either be on top of cotton with opaque desiccant beads below the cotton or free moving in a cryotube that contains a desiccant tablet within the cap.
