You may have heard it all before, this test is not for high powered washers...this test is meant to use with the manufacturer's product. What you may not have heard, is that this test 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. Last year, 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®(Test Object Surgical Instrument) 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 insure 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.
