At safelyBack, we first took a step back and listened to front line medical workers to identify the gaps in unmanaged testing. Then we methodically built a fully-integrated, cyclical screening solution using pre-contagious detection for risk reduction. The SafelyBack mobile app and enterprise portal are integrated for cyclical COVID screening, adverse event notification, and fine-grained contact tracing. Flexible to support new tests, multi-step protocols, and emerging vaccines. Tailored role-based testing, guest solutions, and cost recovery tools. Privacy-by-design provides high-integrity identity and user-mediated sharing where possible.
