FAVN Frequently Asked Questions

Results - Specimen Submission - Specimen Shipping


When are the results ready? 
FAVN test results are normally available within 3 to 4 weeks from the date that the sample is received. If you will be traveling in less than 3 weeks, an expedited STAT service is available.

Some factors affecting the turnaround time that are beyond the control of the laboratory are:

  • Number of samples to be tested – if more samples arrive at one time the turnaround time will be longer because there is a limit as to how many samples that can be tested in a day.
  • Availability and viability of tissue culture cells – Cells are live and can be affected by minor changes in environment that can result in set failures (samples will need to be retested) – cells are the most important component of the test system. Also, if more than expected numbers of samples are received, it can take some time to prepare the number of cells needed for testing.
  • Virus growth – Similar to cells, virus growth can be affected by minor changes in the environment (temperature, humidity, pH, etc.). If the virus grows too much or not enough, the set of testing will not pass acceptance criteria (fail) and the samples will need to be retested.
  • Other unexpected conditions – closings due to inclement weather, etc.

How and where is the official FAVN report sent?

The official FAVN report is sent out in one of the following ways:

Some destinations, such as Hawaii, Guam and islands in the Caribbean, require that the official FAVN report be sent directly to their Department of Agriculture. Therefore a copy of the FAVN report is faxed or emailed to the submitting clinic. For all other destinations, such as Japan, Australia, Korea, the official FAVN report is sent to the submitting clinic via regular US Postal Service (USPS) mail, or international airmail for submitting clinics located outside the United States. Courier delivery of the official FAVN report may be requested at an additional fee by submitting the Courier Delivery Form with the sample(s). It is highly recommended for clinics located in countries where the postal system is slow or unreliable to use the courier delivery option.

The FAVN report can be sent directly to the pet owner with written permission from the submitting clinic Upon request, a copy of the FAVN report also can be sent via email or fax to USDA veterinarians or quarantine stations.

How do I request an original result?
If you have lost or require a new original FAVN report, a new one can be reissued. Please note that a fee will be incurred for this service.

If you are the submitting clinic, please call us at (785) 532-4483 to request a reissue. If you are the pet owner, please have your submitting clinic contact us for a reissue.

If you require just a copy of the official FAVN Report, we can email/fax a copy to the submitting clinic, or any government authority free of charge.

How do I request a reissue of an official FAVN report? 
A reissued official FAVN report may be requested for an additional fee by submitting a completed Reissue Form. The reissued FAVN Report will be sent to the submitting clinic, unless the submitting clinic authorizes release directly to the pet owner.

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.

Is the FAVN Test the same as the RNATT? 
Yes, the RNATT (Rabies Neutralizing Antibody Titre Test) is the same as the FAVN test.

Why is the FAVN test needed for my pet? 
The FAVN test is required by many rabies-free countries or regions in order for dogs and cats to qualify for a reduced quarantine period prior to entry. Some of these regions are Hawaii, Guam, Japan, St. Kitts and Nevis, Australia, and New Zealand. Always check with the destination authority to verify the pet importation requirements.

When does the 120 day countdown begin for Hawaii?
The day the sample is received at the Rabies Laboratory begins the countdown. This receive 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://hawaii.gov/hdoa/ai/aqs/info for more information.

How long should I wait after my pet has been vaccinated before drawing the sample? 
We advise waiting 21 days between vaccination and taking a blood sample from your pet to allow them sufficient time to develop an antibody response. However, some countries have different requirements. Therefore, we strongly recommend directly contacting regulatory authorities in the country of your destination.

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 the 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 vaccinationsbeginning with the most recent. Please check with the destination for their specific requirements.

My sample is grossly hemolyzed (reddish) or lipemic (fatty). Will it affect the testing? 
Yes it can affect the testing, and may cause the test to be invalid. To reduce the chance of hemolysis, pour off serum from the clot. To avoid lipemia, a fasting sample is recommended.

I need to make a change(s) on my FAVN Report Form. What should I do?
Before the test is finalized, the submitting clinic can contact the Rabies Laboratory about changes.

After the test is finalized, no changes to the information on the form can be made by the Rabies Laboratory, even in the case of minor clerical errors. The submitting clinic or pet owner should contact the destination authorities or USDA vet https://www.aphis.usda.gov/aphis/pet-travel. If you think the Rabies Laboratory made an error on the result label of the official FAVN report, you may contact us. Any error due to a misinterpretation of handwriting will be reviewed on a case by case basis.

My pet’s rabies titer failed (was less than 0.50 IU/mL). What should I do now? 
Most rabies-free countries have extended quarantine periods for pets that don’t meet minimum requirements. Alternatively, consult your veterinarian about the possibility of an additional rabies vaccination and collecting another blood sample. It is best to wait 2-3 weeks 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.

Specimen Submission:

Can I draw the sample in a serum separator tube?
Yes, the sample can be collected in a serum separator tube and then poured off into a 3.0 to 5.0 mL red top tube.

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

Specimen Shipping:

What kind of ice should I use to send in my samples?
A sufficient amount of pre-frozen gel packs or cold packs for the anticipated duration of transit should be placed in the package.

Does the laboratory accept weekend delivery?
We accept deliveries Monday-Friday 8am-5pm [CST], excluding State Holidays. Samples can be refrigerated over the weekend.

Will I receive a confirmation when the Rabies Laboratory receives my samples? 
We do not send sample receipt confirmation. Please track your package to confirm we have received your sample. One to two days after the sample is received, you may use your microchip number to check the sample’s status at: http://www.vet.ksu.edu/depts/rabies/RabiesSearch/caseSearch.aspx.

Do I need to attach any kind of bio-hazard label on my shipping package? 
The FAVN sample is considered an “exempt animal specimen”, however each shipping company has their own rules, please check with them prior to sending your sample.

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

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.

Are you an EU certified lab? 
Yes, we are an EU certified lab.

I sent in my samples but I have not been billed yet for the FAVN test. Is something wrong? 
Invoices are sent on the first business day of the month. For billing inquiries, please contact the Business Office at 785-532-3294 or vdlbusiness@vet.k-state.edu.

Where is the official FAVN report document?
If the destination line of the FAVN Report Form said Hawaii, Guam or any of the Caribbean Islands, the official document was sent to the destination. If the pet is traveling to another destination, the official document was sent to the submitting laboratory or clinic.
