Auburn Rabies Titer Test: What It Is, How It Works, and When You Need It
Key takeaways
- The Auburn rabies titer test refers to FAVN or RFFIT serology at Auburn University College of Veterinary Medicine’s Serology-Virology Laboratory.
- For international pet travel to rabies-free destinations, Auburn states FAVN—not RFFIT—is required.
- A commonly cited passing FAVN result is ≥0.50 IU/mL; a pass alone does not guarantee destination entry.
- As of September 2026, standard FAVN turnaround is about 3–4 weeks after sample arrival; expedited FAVN is typically 1–2 weeks.
- Auburn is USDA-recognized for export FAVN, EU-designated (approval dated 15 April 2016), and CDC-listed—but not currently approved for Japan travel.
- Only a veterinary clinic can submit serum; tubes for travel must be labeled with the microchip number or they are cancelled.
- USDA APHIS lists Auburn among approved titer labs for China pathways reviewed here, while Japan’s APHIS-listed labs are Kansas State and DoD—not Auburn.
- Animal Passport’s muzzle-biometric livestock ID is not a government travel document and does not replace official FAVN or USDA paperwork.
The Auburn rabies titer test is a rabies antibody serology assay performed at the Auburn University College of Veterinary Medicine Serology-Virology Laboratory. As of September 2026, international pet travel usually requires the Fluorescent Antibody Virus Neutralization (FAVN) test—not the Rapid Fluorescent Focus Inhibition Test (RFFIT)—with a commonly accepted passing result of ≥0.50 IU/mL. Standard FAVN turnaround is about 3–4 weeks after the sample arrives; expedited FAVN is typically 1–2 weeks. Auburn is USDA-recognized for export testing and appears on European Union (EU) and U.S. Centers for Disease Control and Prevention (CDC) approved-lab lists, but it is not currently approved for travel to Japan.
This guide explains which Auburn assay fits your purpose, how clinics submit samples, how destination rules differ, and how a digital livestock identity record differs from official pet-travel paperwork. For related vaccination and identity topics, see the Animal Passport blog.
What Is the Auburn Rabies Titer Test?
In search and clinic language, “Auburn rabies titer test” means rabies antibody testing ordered through Auburn’s Serology-Virology Lab in Auburn, Alabama. The lab offers two distinct assays:
- FAVN — the assay Auburn positions for international pet travel documentation.
- RFFIT — a rabies antibody titer used for vaccination or routine screening purposes; Auburn states the RFFIT is not offered for pet travel.
According to Auburn University College of Veterinary Medicine (2026), the Serology-Virology Lab is recognized by the United States Department of Agriculture (USDA) to carry out FAVN rabies antibody titer testing for export for pet travel, is an EU-approved laboratory, and is on the CDC approved list. The lab accepts serum for FAVN from a licensed veterinarian. Auburn’s Rabies Serology page (2026) also notes A2LA accreditation (certificate 7878.01) for FAVN and RFFIT testing.
Pet owners cannot mail samples directly. Auburn’s Pet Owners Serology FAQs (2026) state that samples must be submitted through a veterinary clinic.
FAVN vs RFFIT at Auburn
Choosing the wrong assay is one of the most common—and costly—mistakes in pet export planning.
| Feature | FAVN (travel) | RFFIT (non-travel) |
|---|---|---|
| Primary use at Auburn | International pet travel documentation | Vaccination / screening titers |
| Accepted for rabies-free destinations? | Yes, when the destination accepts Auburn’s report | No — Auburn says FAVN is required for those destinations |
| Typical turnaround (Auburn, 2026) | ~3–4 weeks after sample arrival; expedited ~1–2 weeks | ~1–2 weeks |
| Common pass threshold cited | ≥0.50 IU/mL | Many authorities cite ≥0.50 IU/mL for presumed protection |
| Diagnoses rabies infection? | No | No |
Auburn’s Pet Owners Serology FAQs (2026) confirm that the OIE-FAVN and FAVN tests are the same assay, and that a passing FAVN (≥0.50 IU/mL) shows an acceptable antibody response by international standards—but does not by itself guarantee entry into a destination country.
Approvals: USDA, EU, CDC—and the Japan Exception
USDA recognition for export testing
Auburn states it is recognized by the USDA to perform FAVN for pet-travel export. Separately, the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) tells owners that destination countries set entry rules, and that a USDA-accredited veterinarian should confirm vaccinations, tests, treatments, and health-certificate endorsement through the Veterinary Export Health Certification System (VEHCS) when required. APHIS’s pet-export overview was last modified August 14, 2026.
European Commission designated laboratory
The European Commission’s list of designated laboratories in non-EU countries performing rabies antibody titration tests includes Auburn University – College of Veterinary Medicine – Department of Pathobiology – Virology Laboratory, with a date of approval of 15 April 2016 and no expiry date shown on the published entry. Auburn’s own Pet Owners FAQs (2026) state the laboratory is EU-certified for rabies serology testing.
CDC-approved rabies serology laboratory
The CDC’s page “Approved Rabies Serology Laboratories for Testing Dogs,” updated July 13, 2026, lists Auburn University College of Veterinary Medicine Department of Pathobiology among U.S. CDC-approved labs. CDC requires approved-lab serology for certain foreign-vaccinated dogs from high-risk countries entering the United States; without a valid result, CDC describes a path that can include 28-day quarantine at a CDC-registered animal care facility.
Japan: Auburn is not currently approved
As of September 2026, Auburn’s Serology-Virology Lab repeatedly states it is not currently approved for travel to Japan. USDA APHIS’s Japan pet-travel page (last modified July 30, 2025) lists approved rabies titer laboratories for dogs and cats entering Japan from most U.S. states as Kansas State University Rabies Laboratory and the DoD Veterinary Food Analysis and Diagnostic Laboratory—not Auburn. Japan also requires a titer ≥0.5 IU/ml and a wait of at least 180 days between sampling and arrival, per APHIS.
If Japan is your destination, do not assume an Auburn FAVN report will be accepted—confirm the Japan-approved laboratory list with APHIS and Japan’s Animal Quarantine Service (AQS) before drawing blood.
China: Auburn is listed by APHIS
By contrast, USDA APHIS’s China pet-travel guidance (last modified February 11, 2026) lists Auburn University College of Veterinary Medicine, Department of Pathobiology Virology Laboratory among approved rabies titer laboratories for U.S. dogs and cats seeking entry without the designated-port quarantine pathway. APHIS states the animal must show an antibody titer of at least 0.5 IU/mL, and that titer sampling information is considered valid for up to one year after the sampling date for China under those rules.
Destination rules disagree across countries. Always verify the current APHIS country page and the destination authority before locking a lab or travel date.
How to Get an Auburn Rabies Titer Test: Step by Step
- Confirm the destination’s exact lab and timing rules with a USDA-accredited veterinarian and the official destination authority. Auburn’s FAQs state the laboratory cannot determine country-specific entry requirements.
- Ensure ISO-compliant microchip identification before blood collection when required. Auburn says microchip identification must be implanted prior to sample draw; unlabeled tubes for travel samples are cancelled without exception.
- Complete required rabies vaccination history. Auburn’s Pet Owners FAQs (2026) generally recommend at least two rabies vaccinations before FAVN for optimal antibody response, and suggest blood collection 10–21 days after a booster or 14–30 days after a primary vaccination—always confirming destination-specific timing.
- Have the clinic draw and prepare serum. Domestic and international Auburn submission pages specify spinning a serum separator tube, then pouring 1 to 2 mL of serum into a 3.0 or 5.0 mL untreated red- or white-top tube labeled with the animal’s microchip number.
- Complete the FAVN Report Form carefully. Auburn warns that form information becomes part of the official stickered travel document, and that once a sample is entered, changes cannot be made until results are finalized.
- Ship Monday–Thursday timing when possible. Domestic guidance recommends transit of no more than 2 days via UPS or FedEx, and asks clinics not to ship on Friday. The lab accepts packages Monday–Friday, 8 a.m.–5 p.m. Central time, excluding state holidays, at Auburn University College of Veterinary Medicine Serology-Virology Lab, 350 Greene Hall Annex, Auburn, AL 36849-5519 (international submissions also list 1130 Wire Road).
- Request expedited FAVN only through the portal first if needed. Auburn’s Expedited FAVN page (2026) requires the clinic to enter the online request before the sample is sent; turnaround is 1–2 weeks from receipt and portal acceptance.
- Receive the stickered official report via the clinic. Results are printed on an adhesive sticker placed on a copy of the submitted FAVN Report Form; the original form stays on file at Auburn.
Turnaround Times, Fees, and Shipping Costs
As of September 2026, Auburn publishes these timing estimates on its Serology-Virology pages:
- FAVN: approximately 3–4 weeks from sample arrival
- Expedited FAVN: 1–2 weeks after receipt and portal acceptance
- RFFIT: 1–2 weeks
- Other diagnostic serologies and vaccine titers: 2–3 business days
Auburn directs clinics to its Pathobiology Diagnostic Services online catalog for the complete fee list rather than posting a single public FAVN price on the main FAQ pages. Published ancillary amounts include a domestic FedEx report delivery flat rate of $25.00, an international FedEx report delivery flat rate of $60.00, a domestic FedEx specimen shipping label option at $25.00 (with dimensional pricing if the package exceeds 12” × 12” × 12”), and a $5.00 accession fee on expedited accessions. International clinics must pay before testing; domestic U.S. clinics are invoiced monthly and should not prepay for standard FAVN.
Clinic blood-draw, exam, and USDA health-certificate endorsement fees are separate and vary by practice and destination.
What a Passing Result Means—and What It Does Not
Auburn defines a passing FAVN as ≥0.50 IU/mL. That figure matches thresholds cited by USDA APHIS for Japan (≥0.5 IU/ml) and China (≥0.5 IU/mL) on the country pages reviewed for this article. If the result is below 0.50 IU/mL, Auburn’s Pet Owners FAQs advise consulting the veterinarian about a booster and repeat testing; some destinations may require quarantine if minima are not met.
A titer does not diagnose rabies infection. It also does not replace microchip rules, waiting periods, parasite treatments, airline policies, or USDA-endorsed health certificates. Validity length is set by the destination—not by Auburn alone.
Official Pet Travel Documents vs Animal Passport Digital ID
Search results for rabies titers often mix three different systems:
- Official export health certificates and lab reports — government and destination quarantine documents (for example, USDA APHIS-endorsed certificates and an Auburn stickered FAVN Report Form).
- EU pet passport / PETS-style schemes — official companion-animal movement frameworks under EU and related national rules, which are not the same product as a private veterinary lab report.
- Animal Passport — a digital animal and livestock identity product that uses muzzle biometrics (a nose print unique like a fingerprint), phone-based capture, and records that bind owner, breed, estimated age, body condition, and vaccination history. Age can be estimated from a dental photograph with a confidence score, and body condition can be scored 1–5 from a side-profile photo. It was used in livestock flood rescue in Pakistan in August 2025 so farmers could reclaim animals when paper tags washed away.
Animal Passport is not a government-issued travel document and does not replace FAVN reports, USDA endorsements, or destination quarantine certificates. It can help keep vaccination history and identity attached to an animal when paper records fail—useful context alongside formal rabies-testing paperwork, not a substitute for it.
Planning Timeline for International Travel
Because FAVN alone can take 3–4 weeks—and destinations may add waiting periods measured in months—start with a USDA-accredited veterinarian as soon as travel is contemplated. CDC guidance for certain U.S. dog imports recommends discussing serology at least 60 days or more before travel when an approved-lab titer is required. Japan’s 180-day wait after sampling, described by USDA APHIS, is a separate calendar constraint that can dominate trip planning even when the lab returns results quickly.
Build a checklist that includes microchip timing relative to vaccination, vaccination count and dates, serum draw window, lab approval for that destination, waiting period, health-certificate endorsement, and airline acceptance of pets in cabin or cargo.
Key Takeaways for Clinics and Owners
Email is Auburn’s preferred contact channel for lab process questions ([email protected]); the lab states it does not accept phone calls. Timing of vaccine versus serum draw should be discussed with the veterinarian using the destination country’s own criteria. For ongoing identity and vaccination-history workflows on livestock and working animals, explore how digital records are organized on animalpassport.co and related posts on the blogs hub.
As of September 2026, treat “Auburn rabies titer test” as clinic-submitted FAVN (or non-travel RFFIT) at Auburn’s Serology-Virology Lab: confirm destination lab approval first, aim for ≥0.50 IU/mL, budget weeks for results, and never confuse a private digital livestock passport with official pet-export documents.
