The PDX-SIB test from Hardy Diagnostics is both reliable and inexpensive with presumptive results available for the most common Salmonella species within 24 to 48 hours. No subculturing or specimen transfers are required. The test is AOAC-RI approved. The product is specifically designed as a critical control point surveillance tool. The PDX-SIB collection and test system is a closed system; once the broth media is inoculated, the tube remains closed for the remainder of the test.
