Approved Tests. Approved tests for Trichomoniasis testing within
the State of Texas shall include the culture or Polymerase Chain Reaction
(PCR) testing of samples collected by certified veterinarians following
approved collection, handling and shipping protocols, then tested
in approved laboratories.
(1) Official Culture Tests. An official test is one
in which the sample, collected in an InPouch, is received in the official
laboratory, in good condition, within 48 hours of collection or is
incubated in an InPouch by the collecting veterinarian for 48 hours
after collection, and such sample is submitted to be tested according
to the "Official Protocol for Culture of Trichomoniasis." Samples
in transit for more than 48 hours will not be accepted for official
culture testing. During transportation, the organisms should be protected
from exposure to daylight and extremes of temperature, which should
remain above 15 degrees Celsius (59 degrees Fahrenheit) and below
37 degrees Celsius (98.6 degrees Fahrenheit).
(2) Official Polymerase Chain Reaction (PCR) Tests.
PCR is accepted as an official test or an official confirmatory test
when completed by a qualified laboratory, approved by the Executive
Director, and meets the following requirements:
(A) A Trichomoniasis sample submitted in an InPouch
must be received in the official laboratory, in good condition, within
48 hours of collection or incubated by the collecting veterinarian
for 48 hours after collection and submitted to arrive at the laboratory
within 96 hours of collection. Trichomoniasis samples pooled at the
laboratory may qualify as official tests at a ratio of up to five
individually collected samples pooled for one test. Veterinary practitioners
may not submit pooled samples for an official test.
(B) A Trichomoniasis sample submitted in phosphate
buffered saline (PBS) or sterile saline must be received in the official
laboratory, in good condition, within 120 hours of collection. Trichomoniasis
samples pooled at the laboratory may qualify as official tests at
a ratio of up to five individually collected samples pooled for one
test. Veterinary practitioners may not submit pooled samples for an
official test.
(3) Other Official Tests. Other tests for Trichomoniasis
may be approved by the Commission, as official tests, after the tests
have been proven effective by research, have been evaluated sufficiently
to determine efficacy, and a protocol for use of the test has been
established.
