Today, the Bowie-Dick (BD) test is widely used and recognized as a valuable means of monitoring the performance of vacuum-assisted steam sterilizers. However, several aspects have changed since the original work was done in Britain in the early 1960s.1Bowie et al. introduced a simple test to detect inadequate air removal in prevacuum steam sterilizers, because this air could lead to sterilization failure.
They created a stack of porous towels with an indicator sheet placed at the center. When processed in an
empty chamber, the indicator experienced a color change; an uneven color change indicated residual air or poor steam penetration. Their work demonstrated that sterilizers could pass routine checks yet fail to remove air effectively, highlighting the need for daily testing. This became the foundation for the BD test, which is now used globally as the standard for monitoring pre-vacuum sterilizer performance.
