Hardy Diagnostics' PDX-SIB test provides presumptive results for the most common species within 24 to 48 hours, with no sub-culturing or specimen transfers required. The selective enrichment media contains a -specific color change indicator, which turns the PDX-SIB broth yellow when is present. This AOAC-RI-approved collection and test system is a closed system.
