Real-time PCR panel that detects Equine Herpesviruses 1 and 4, Equine Adenoviruses 1 and 2, Equine Rhinitis viruses A and B, Influenza A virus (matrix), Equine arteritis virus and Streptococcus equi subsp. equi.


NOTE: For EHV-1 and EHV-4 suspect horses, it is also recommended that you submit an EDTA whole blood sample at the same time as you submit the nasal swab, for EHV-1 and EHV-4 PCR testing. This broad respiratory panel is not appropriate for testing whole blood since only EHV-1 and EHV-4 would be likely to be detected in a blood sample. Blood specimens submitted with respiratory samples will be tested for EHVPNL (both EHV-1 and EHV-4) and additional fees will be applied. Contact laboratory to discuss testing options.


Test Code: ERPNL

Test Days:M-W
Turn Around Time (Days):5-7 days

Nasopharyngeal wash, tracheal wash and broncho-alveolar lavage samples are also appropriate respiratory samples from horses.
Post-mortem lung tissue can also be tested.


Submit swabs in sterile, sealed vials with several drops of saline added, to prevent desiccation. Bacterial gel transport media are not appropriate for PCR assays. If culture is desired, submit a separate swab in an acceptable bacterial transport media. Cotton, plastic, wood-handled, and Dacron and other synthetic swabs are all acceptable for PCR-based assays. Calcium alginate swabs should be avoided.

Leak-proof sterile container for tissues.
