The official laboratory test shall be a polymerase chain reaction (PCR), or other technologies as approved by the State Veterinarian and adopted through a Directors Administrative Order.  The test is not considered official until results are reported by the testing laboratory.

1.  All Arizona origin bulls sold, leased, gifted, exchanged or otherwise changing possession for breeding purposes in Arizona shall be tested for T. foetus via Official T. feotus bull test prior to sale or change of ownership in the state, unless going to direct slaughter.  T. foetus testing shall be performed on bulls prior to change of ownership of that bull.

2.  The Official T. foetus test shall be collected by an Accredited Veterinarian and performed though an Approved Laboratory.

3.  Pooled testing is not an official test.
