Molecular Diagnostics

The Molecular Biology section utilizes Polymerase Chain Reaction (PCR) technology to detect the presence of nucleic acids (DNA/RNA) from pathogenic organisms in clinical samples. Molecular diagnostic tests are fast and more sensitive when compared to other conventional methods such as bacterial culture or virus isolation. A wide variety of tests are available for bacteria, fungi, and viruses from many animal species, including pathogens of cattle, cats, dogs, horses, marine mammals, exotics, birds and laboratory animals.

Results can be obtained as early as 24 hours from sample receipt, in most cases. Please see our INTERACTIVE LAB TESTS & FEE SCHEDULE for available tests, appropriate samples for submission, and turn-around time. Please, check our list on a regular basis as new tests are added frequently.

Note:
It is important to remember that a positive PCR test result may indicate an active infection or presence of the organism (live/dead) in the sample submitted. False negative results may occur due to low numbers of the organisms or PCR inhibitory factors present in the sample. Like with any other testing methods, factors such as clinical signs, species of animal tested, and sample sites should be considered for reliable interpretation of test results.
