Interpretation of Flock Level MV Test Results

a.
A NEGATIVE Whole Flock Test Result requires that
i.
All sheep ≥ 180 days of age in the flock were sampled within the same time frame (within 7
days of each other
) and found to test either all as NEGATIVE on the initial test result, or
ii.
If any animals test SUSPECT, that all those animals received a NEGATIVE test when re-sampled
within 30 days of the test date.
(1)
The HYPHEN Elitest does not have a SUSPECT category.
iii.
If one or more animals in the flock do not receive a NEGATIVE test either initially or on re- sampling, then the flock test is not considered NEGATIVE.
 
b.
A NEGATIVE Monitored or "A" Status Flock Test Result requires that
i.
A random sample of sheep ≥ 365 days of age in the flock were sampled within the same time frame (within 7 days of each other) and found to test either all as NEGATIVE on the initial test result or
ii.
If any animals receive a SUSPECT result, that all SUSPECT animals all received a NEGATIVE test when re-sampled within 30 days of the initial test.
(1)
The HYPHEN Elitest does not have a SUSPECT category.
iii.
If one or more animals receive a POSITIVE test either initially or on re-sampling, then the flock test is not considered NEGATIVE.
