FAVN Frequently Asked Questions

Which test do I choose FAVN or RFFIT Testing?

The FAVN test must be submitted for pet travel.

Are you an EU certified lab for rabies serology for pet travel?
Yes, we are an EU certified lab

Why is the FAVN test needed for my pet?
The FAVN test is required by many rabies-free countries, regions or islands in order for dogs and cats to qualify for a reduced quarantine period prior to entry. A passing FAVN result ((>/= 0.5 IU/mL) provides proof of adequate response to rabies vaccination.

Is the FAVN Test the same as the OIE-FAVN Testing?
Yes, the OIE-FAVN (Office International des Epizooties) test is same as the FAVN test; the test is performed following the FAVN procedure in the OIE manual.

Is the FAVN Test the same as the RNATT?
Yes, the RNATT (Rabies Neutralizing Antibody Titre Test) is the same as the FAVN test. RNATT is a generic term which encompasses the FAVN method.

If the pet is travelling to a Rabies Free Country or Island, can I submit the RFFIT?
No, The FAVN test must be submitted for pet travel.

How much does the FAVN testing cost?
Our requirements, policies and costs are updated on our website at Tests and Feess

Sample Submission

How long should I wait after my pet has been vaccinated before drawing the sample?
For the highest probability of obtaining a passing result, we recommend the pet be rabies vaccinated a minimum of two times. For optimum antibody response, wait 10-21 days between vaccination and taking the blood sample for testing (or 14-30 days if taking the blood sample after primary vaccination). However, some countries have strict requirements for the timing of the blood draw. Therefore, we strongly recommend directly contacting regulatory authorities in the country of your destination or your state USDA Vet Med Officer.

Is a fasted sample required?
A fasted sample is not needed unless the sample is grossly lipemic. To avoid submitting a lipemic sample, fast the animal 8 -12 hours prior to having the serum drawn.

How much serum do I need?
We recommend 1.0 to 2.0 mLs of serum per submission

Can I draw the sample in a serum separator tube?
Yes, the sample can be collected and sent in a serum separator tube (gel separated, red-top tube, tiger-top tube). However, if a serum separator tube is used, it is best to pour off the serum into a non-additive 3.0 to 5.0 mL tube and send only the serum part of the sample.

How long can serum be stored?
We recommend serum storage be no more than 7-10 days in refrigeration before shipment. For longer storage you can freeze the serum at -20 °C.

My sample is grossly hemolyzed (reddish) or lipemic (fatty). Will it affect the testing?
A simple test is to hold the serum tube in front of a printed page – if you can see the print through the sample, then it is acceptable to test. If the sample is toxic to our cells due to hemolysis, lipemia, or contamination, a ‘toxic’ result will be sent out, and testing fees may apply. To reduce the chance of hemolysis, pour off serum from the clot into a transfer tube for submission. To avoid lipemia, a fasting sample (8-12 hours) is recommended. If sufficient serum sample can be pipetted from the submitted tube, we will test it.

My pet has two microchip numbers, which one should I list on my FAVN form?
If an animal has two microchips, the first number listed on the submission form is the only one that will be on the official FAVN result label. Most destinations require an ISO microchip be implanted before the blood sample is drawn. Some destinations have scanners that only read certain brands of microchips. Choose which microchip to list first based on these and any other criteria the destination may have.

How much history of the rabies vaccination should I provide?
Record the dates of 2-3 rabies vaccinations beginning with the most recent. Please check with the destination for their specific requirements. It is recommended the animal have a minimum of two rabies vaccinations for best chance of achieving a passing titer of 0.5 IU/mL.

Pet Travel Requirements

Can you help me with the Destination requirements?
The Rabies lab’s function is to test the serum and provide a result. Please contact the quarantine authority of the intended destination or access the USDA website at the following link: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/export for current requirements per destination.

When does the 120 day countdown begin for Hawaii?
The day the sample is received at the Rabies Laboratory begins the countdown. This received date will appear on the result label of the official FAVN report. As long as the titer result is at or above the passing level (>/= 0.5 IU/mL) and travel is 120 days after the received date, the animal will be eligible to enter Hawaii. Please see http://hdoa.hawaii.gov/ai/aqs/animal-quarantine-microchip-search/ for more information

Does the Veterinarian have to be Accredited?
Yes, the identity of the veterinarian is critical to assessing the biosecurity risk associated with the animal. The USDA has an understandably rigid view that only USDA accredited veterinarians can undertake the testing, treatments and examinations needed for the purposes of importing dogs and cats to Rabies Free Countries or Islands.

How will I know if my Veterinarian is a USDA Accredited?
Information regarding The National Veterinary Accreditation Program is available at this link: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/nvap

Who will endorse the Rabies and Health Certificate?
IREGS for Animal Exports is at this link: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/export/iregs-for-animal-exports/ct_iregs_animal_exports_home

I don’t understand the regulations for exporting animals.
If you have questions or concerns regarding regulations for exporting animals to a foreign country, you can contact the Veterinary Services service center in the State from which the animals will be exported. For import/export questions, contact your National Import Export Service Center . https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/nvap/ct_areavet

Can the pet owner submit the sample for FAVN testing ?
Pet owners should check with the veterinarian for permission to schedule the shipment of the sample. The clinic or reference laboratory is responsible for the sample draw labeling, packaging, and associated services. Results will be sent to the submitting clinic or reference laboratory unless written permission to send the results directly to the pet owner is given by the submitting clinic or reference laboratory.

Do I need to attach any kind of bio-hazard label on my shipping package?
A FAVN sample is considered an “exempt animal specimen”, therefore most courier companies do not require special labeling. If in doubt, please check the shipping company prior to sending your sample.

For International Shipments, Please fill out: Customs Declaration for Animal Serum Export to the US https://www.vet.k-state.edu/asp/Forms/ksvdl/Ups-Label available at this link: A copy of the FAVN REPORT FORM and the Customs documents should be placed on the outside of the package for custom agents to keep. Also place the original FAVN REPORT FORM and Customs Documents in the box. The animal’s microchip number MUST be on the serum tube and the FAVN REPORT FORM to ensure testing. Samples arriving without a microchip number will be cancelled.

Does the laboratory accept weekend delivery?
We accept deliveries Monday-Friday 8am-5pm [CST], excluding State Holidays. Samples for Saturday Delivery will be received, but not processed until the following business day. Create a UPS shipping label at this link: https://www.vet.k-state.edu/asp/Forms/ksvdl/Ups-Label

Will I receive confirmation of receipt of my sample?
The K-State Rabies Laboratory receives thousands of samples per week. To determine if we have received your sample, please track the package to our location, and by the next business day you can search for the animal’s microchip number on our website. http://www.ksvdl.org/rabies-laboratory/favn-test/Rabies-Search/

Can you tell me the status of my samples?
To determine status of the FAVN test on your sample, you can utilize the FAVN Microchip Status Search at the following link: http://www.ksvdl.org/rabies-laboratory/favn-test/Rabies-Search/

The sample will go through four status stages, New – meaning the sample has been received, Working – meaning the sample is prepped or in the testing phase, Review – testing has been completed, but we are verifying paperwork and QA/QC of the testing process, and Finalized – meaning the sample’s results have been sent. (An electronic result will be sent as soon as the result is finalized in the laboratory information management system. See “How and where is the official FAVN report sent?” for information about the Official Stickered Copy.)


When are the results ready?
The delivery time of the FAVN test results may vary without notice. Please check with the laboratory rabies@vet.k-state.edu for an up-to-date estimate of the turnaround time

My pet’s rabies titer failed (was less than 0.50 IU/mL). What should I do now? We recommend a minimum of two rabies vaccinations before taking the blood sample for FAVN testing. Most rabies-free countries have extended quarantine periods for pets that don’t meet minimum requirements. Alternatively, consult with your veterinarian about the possibility of an additional rabies vaccination and collecting another blood sample. It is best to wait 10-21 days after re-vaccination to take a blood sample so that the pet has time to develop a higher antibody response. Please carefully read and interpret the results on the report and contact us if you have questions

How long is the FAVN test valid?
The destination countries decide how long the FAVN test result is valid for, please check directly with them. For Hawaii, please go to http://hdoa.hawaii.gov/ai/aqs/animal-quarantine-microchip-search/ for more information.

How and where is the official FAVN report sent?
