When test samples are being cultured in the lab, our lab partner, Dentisafe, can detect “fast failures”, which means the sample quickly exceeds the microbial limit of 500 CFU/mL. This enables us to then provide immediate, early notification prior to completing the full incubation period. So if we know, we let you know, right away. You then receive an official test report after the full incubation period is complete for all samples submitted.

Knowing sooner that your water is unsafe and non-compliant enables faster action to remediate and restore safety, and to head off further growth of harmful microbes before they continue to multiply. With FASTRead, you now have a new weapon in the battle against biofilm.

With an R2A test, the cell count can only increase over time. So a “false failure” is extremely unlikely if your sample has already passed the 500 CFU/mL level. If you don’t receive a FASTRead failure notification, we can’t yet know if your sample will pass or fail until the end of the incubation period. You’ll receive a final test report that reports your final results, but they won’t be different than a FASTRead result (a “fast failure”).

We don’t report a passing result until full incubation period has been completed, in order to be certain you aren’t receiving a “false passing” result. We can only know sooner if your sample has failed and exceeds the safety threshold of 500 CFU/mL before incubation is complete.

FASTRead is just a reporting feature within the approved R2A test method.

Yes, all Sterisil R2A tests, even those purchased in the past, will be processed using the FASTRead notification feature. This is true even if the test envelope isn’t labeled “FASTRead”.

No, you collect, ship and retrieve your results as usual.
