(two) The sterility test have to be validated to display the test is capable of reliably and continually detecting the presence of practical contaminating microorganisms.

Sterile, enclosed models make it possible for for the simultaneous filtration of equivalent volumes of test samples through two membrane filters.

If progress is noticed and turbidity is found, then a re-test is completed. If expansion is observed again in the second test and cannot be distinguished from the next test, it fails. But if it might be distinguished from the main test, then the 2nd re-test is completed working with twice the number of samples.
