No lab in California runs the FAVN test — your vet draws it, Kansas tests it.

Why “FAVN test near me” has no California answer

The FAVN test — Fluorescent Antibody Virus Neutralization — is the rabies-antibody titer that Japan, Australia, and several other destinations require. It measures your pet’s immune response to the rabies vaccine. No laboratory in California runs it for pet export. Searching “FAVN test Los Angeles” or “rabies titer test San Francisco” won’t find a local lab — because the test isn’t done locally.

What happens instead: your California vet draws the blood, and the serum ships to Kansas State University’s Rabies Laboratory (KSU / KSVDL) in Manhattan, Kansas — the lab USDA-APHIS recognizes for pet-export rabies serology. (Active-duty military can use the DoD lab; everyone else uses KSU.)

How the draw works from a California clinic

You can’t walk in and ask for “a FAVN.” The veterinarian draws the sample and completes and signs the FAVN form, and the clinic ships it (unless the vet gives you permission to ship it yourself). A few rules that trip California owners up:

• The serum tube must be labeled with your pet’s microchip number — unlabeled tubes are cancelled, no exceptions.
• KSU needs 1–2 mL of clear serum; serum keeps refrigerated up to 10 days or frozen for 1 month before it ships.
• Wait 10–21 daysafter the rabies vaccination before the blood draw (14–30 days after a primary vaccination) for the best antibody response.
• A passing titer is ≥ 0.5 IU/mL. Below that, the pet isn’t cleared and the draw is repeated.
• KSU recommends the clinic ship by 1–2 day courier (FedEx, UPS, or DHL) with a frozen gel pack — so budget California-to-Kansas transit on top of lab time.

Timing and cost

KSU’s current FAVN turnaround is an estimated 10–14 calendar days, with no expedited service. Its online submission form is faster and discounted versus paper. From California, add courier time each way, so plan closer to two to three weeks from draw to result.

On price, we’ll be honest: KSU only publishes its FAVN fee inside its online lab portal, so there is no public dollar figure to quote here — your clinic sees it at submission. For context, the DoD FADL charges $70 per privately owned dog or cat, but that lab serves DoD beneficiaries only; non-military owners are directed to KSU, Auburn, or the University of Missouri.

Which destinations need it — and the Japan myth

A FAVN or equivalent rabies titer is required for Japan, Australia, China, South Korea, Taiwan, and Hawaii. (Not every destination wants a titer — see titer vs. vaccination by destination below.) For China, the titer must be at least 0.5 IU/mL and is valid up to one year from the sampling date.

One myth worth killing: KSU results areaccepted for Japan. The APHIS Japan page lists Kansas State among its approved labs. The lab to avoid confusion over is which US labs Japan accepts at all — see which US labs run FAVN tests Japan will accept, and titer vs. vaccination by destination for who wants a titer at all.

Where Pawvisa fits

The one thing California gives you here is the vet who draws and ships the sample correctly the first time. Find one on our California USDA-accredited vet finder, and see the full local picture on the pet export from California hub.

Because the FAVN clock is long and destination-specific, the free 60-second timeline check shows exactly when the draw has to happen for your destination, and the $29 readiness analysisruns your dates against every rule so a mistimed titer doesn’t reset your trip.
