International Reputation of NISSUI Compact Dry
Due to the context in which UNICEF works, laboratory testing for E. coli is typically not feasible. Samples must therefore be processed on-site or nearby, typically with limited access to cold chain transport or grid electricity. These methods typically require special training for the staff conducing the tests, and there are often multiple process steps, leaving room for error and contamination of the samples. Currently UNICEF typically uses the following testing methodologies for E. coli testing in field locations:
- Portable lab kits
- H2S (presence/absence)
- Compartmentalized Bag Test (CBT)
- Compact Dry Plates
