You may have heard it all before, this test is not for high powered washers...this test is meant to be used with the manufacturer's product. What
you may not have heard, is that the TOSI® (Test Object Surgical Instrument) is meant to simulate cleaning of surgical instruments. When you are in the business of properly reprocessing surgical instruments, that is exactly what you need to hear.
Through the past, we spoke in great detail about the "TOSI® Truth" and how this test is biased toward products and methods that are effective
at cleaning blood off of stainless steel instruments. You can read more about it by clicking
here.
The TOSI® is the only test of its kind that is designed to test your washer to make sure surgical instruments are being cleaned effectively by
revealing the hidden areas of instruments. The TOSI® is dried blood soil on a stainless steel coupon. It is just like dried blood on a stainless steel surgical instrument. We mount the plate in a plastic holder with a graduated gap. This is just like the areas
on a surgical instrument which are blocked from direct spray action, such as the box locks. The routine use of this test will help ensure that your instrument washer is performing at a consistent level, enhancing the routine visual inspection of instruments.
TOSI® complies with new AAMI and AORN Guidelines as well as ASTM Guide D7225.
