Sterility Assurance Level

Promethean sterilizes its tissue grafts so that they have a Sterility Assurance Level of 10-6. This means that only one in one million grafts will be non-sterile.

Some competitive grafts claim to be sterile, but only have a Sterility Assurance Level of  10-3.  That means that one graft in a thousand will be non-sterile.  Some grafts are only aseptic and are not sterile at all.  Physicians need to understand the difference and how that can impact the grafts usage.

Tissue Sources

Promethean only accepts tissue donors from AATB accredited groups.
