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.
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.
Each lot of ProTest is certified for population, species, D-value,
z-value (where applicable), purity and expiry. Shelf life is 18 months from the
