Porcine Diagnostic Plans and Panels

The following diagnostic plans have been developed primarily as an educational tool to assist the veterinarian in designing a complete, although not exhaustive, diagnostic strategy. To encourage veterinarians to select only the tests that are deemed clinically appropriate in each situation, the price of the diagnostic plan is not discounted from the sum of the individual test costs.

For the test groupings labeled as panels, there may be a discounted price versus the costs of the individual tests. Diagnostic plans and panels can be requested by writing the complete name as the test request. If appropriate samples are included all tests will be performed.

Antimicrobial susceptibilities for culture isolates are available upon request at an additional charge.

Tests Performed Test Code Samples Needed
(3) Aerobic Bacterial Culture
Listeria included
AER
  • Submit 3 fresh tissue samples: placenta, lung, and stomach contents - labeled and individually bagged; for individual aerobic culture
Histopathology HISTO
  • Formalin fixed tissue: placenta, liver, lung, brain, adrenal, heart, thymus, small intestine, kidney, fetal skin
(2) Leptospira PCR LEPTPCR
  • Submit 2 fresh tissue samples: placenta including cotyledons and fetal kidney; stomach contents acceptable

Porcine Circovirus Type 2 FA

PCV2FA
  • Fresh tissue: heart (preferred), lung, kidney, spleen, thymus, placenta, small intestine
Porcine Parvovirus FA PPARVFA
  • Fresh tissue: lung, intestine, lymph nodes, spleen
Porcine Reproductive Respiratory Syndrome FA (PRRSV) PRRSFA
  • Fresh tissue: lung, kidney, spleen, thymus, placenta, small intestine
Virus Isolation VI
  • Fresh tissue: lung, thoracic fluid, placenta, stomach contents, kidney, liver, heart, spleen, lymph nodes, adrenal, skin, intestine, Heart blood (serum), peritoneal, pleural, or pericardial fluid in sterile red top tube.

For cases with mummified fetuses you may also want to consider Porcine Parvovirus HI and Porcine Circovirus-2 IFA on fetal heart blood. For comprehensive rule out of PRRSV, the PCR is recommended on lung and/or thoracic fluid. If abortion is suspected to be related to ventilation then carbon monoxide testing on heart blood in an EDTA tube or a red top or thoracic fluid is recommended.

Porcine Diarrhea, Nursing Pigs Diagnostic Plan
