This world was sterile, by the most sensitive tests that man could apply to it.
And the department has now added to its repertoire the more sensitive test that was used in England.
A more sensitive genetic test can detect the presence of the virus itself.
The Machine was undergoing sensitive physical tests at this moment.
With the evolution of more specific and sensitive tests, this ideal has become impossible.
His research led to the development of the most sensitive test for calcium in muscle tissue.
And even the most sensitive tests for the virus showed no evidence that they was still present in the mens' blood.
I would also add, in this respect, that research continues on more sensitive tests than are currently available.
Generally there is a trade off between time and sensitivity - so more sensitive tests may take longer to develop.
