1) What sample is required for testing for
each disease?
The PAV-ELISA test requires a very small
amount of blood from the animal to be tested. 1 cc of blood is sufficient
to perform all the tests offered. In the case of CAE and OPP the
test can be performed on colostrum. The high concentration of antibodies
in the colostrum improves the sensitivity of the assay. Colostrum
must be collected in the first 24 hours after kidding or lambing.

2) Can the goat/sheep owner submit samples directly
to PAVL for testing?
Yes, samples can be submitted directly to PAVL
for testing. This does not diminish the role of the veterinarian
in animal care and we recommend that you always consult your veterinarian
for animal health issues.

3) How should samples be shipped to ensure safe
and timely arrival at PAVL?
IMPORTANT! Recent revisions
in the regulations concerning packaging of biologic specimens have caused
concern among persons sending samples for diagnostic testing. The following
link explains the specific instructions for packaging samples to meet
the new regulations. **** Packing Instructions

4) What age should animals be in order to get
the most reliable test results?
CAE and Johne's tests are more reliable when
the animal is at least six months of age. Prior to this age a negative
result is not reliable due to low levels of antibody and a positive result
may be due to maternal (mother's) antibody via milk consumption.
All other diseases are not age dependent for test data reliability.

5) What days are the tests performed?
Normal test days are Tuesday and Friday.
Some variation from this schedule is possible depending on workload.
If you need samples tested at other times we will make every effort to
accommodate, although a small “rush” charge may apply.
Please call us to schedule special testing needs.
