Experiencing persistent disease challenges in your flock or herd? Selection pressures on viruses cause the pathogens to evolve as they replicate and cause disease in animal populations, even with a vaccination program in place. Larad is committed to providing you with the highest quality diagnostic services to correctly identify the strain or subtype of the virus on the farm using cutting-edge molecular technology.
Once the strain of the virus is identified, we can also work with you to formulate a custom vaccine to meet your needs.
We offer polymerase chain reaction (PCR), reverse transcriptase (RT)PCR, and nucleotide sequence analysis for viral pathogens. While we are capable of testing for most animal viruses, we focus on those viral diseases our VLP products are targeting.
Our focus areas include the following:
• Infectious Bursal Disease Virus (Poultry)
• Avian Reovirus (Poultry)
• Chicken Anemia Virus (Poultry)
• Infectious Pancreatic Necrosis Virus (Fish)
• Infectious Bronchitis Virus (Poultry)
If you require a different type of testing or analysis for a virus that isn't listed, we are happy to help! Contact us to see how we can meet your specific needs.

Instructions for Sample Collection
NOTE on INTERNATIONAL SAMPLES: Before any samples can be sent to the USA, you must obtain a copy of our import permit. Include the import permit and a signed statement of assurance that states the procedures outlined in the import permit were followed.
Collection of Tissue Samples for Diagnosis by RT/PCR (Instructions)
1. Use Whatman FTA cards. Do not write or touch in sample area. Label cards in space provided.
2. Aseptically collect tissue containing the suspect virus. Cut each tissue and press the cut face onto the FTA card surface, 1 sample per each circle. Make sure the samples do not overlap.
3. Make sure there is no excess tissue on cards and allow the cards to dry before closing them. This is important because if the cards are wet when they are shipped, bacteria can grow and contaminate the sample. Examples of poorly prepared cards are shown below:
4. Seal and ship the samples at room temperature, they do not need to be on ice or frozen.
