Abstract
A sterilization process is assessed using a test pack having a tube (16) for simulating the difficult to clean areas of instruments, such as lumens. The tube is disposed in a tray (10), and a biological indicator (30) is connected to a tube open end. Additional biological and chemical indicators (42, 24) are inserted in corresponding receiving wells or pockets (40, 22) of the tray. The test pack is covered with a porous wrapping (54) to simulate the challenge of wrapped instruments. The test pack is inserted in a sterilizer along with instruments to be sterilized. The biological indicator (30) will only register effective sterilization if sufficient sterilant flows through the length of the tube to the indicator.
