Control
The control unit should exhibit turbidity and/or a color change to
or toward yellow. If the control unit does not show signs of
growth, consider the test invalid.
Test
A failed sterilization cycle is indicated by turbidity and/or a
color change to or toward yellow. A test unit that retains its
original color (green for ProTest EO and purple for ProTest Steam)
indicates that sterilization parameters have been met.

z-value (where applicable), purity and expiry. Shelf life is 18
months from the date of manufacture. The above catalog numbers for
ProTest comply with the AAMI ST19/EN 866-7 (Steam) and AAMI ST24/EN
