Rabies Antibody Titer Test (RNATT) for Dog Import

What the rabies titer test (RNATT/FAVN) is, why order matters, the 0.5 IU/mL pass mark, and how it affects your dog import timeline from China.

The rabies antibody titer test (also called RNATT or FAVN) is the single most important — and most time-sensitive — step in importing a dog from China to most countries.

What it is

A blood sample is sent to an approved laboratory to confirm the rabies vaccine produced enough antibodies. A passing result is ≥0.5 IU/mL.

The correct order matters

Implant the ISO microchip first
Give the rabies vaccination (after the chip)
Wait the required interval, then draw blood for the titer test
Some countries — such as Japan — require a 180-day wait after the blood draw

Why timing is everything

If the steps are done out of order, the clock resets. This is the number-one reason imports get delayed — so we plan the full schedule before you reserve.

Which countries require it

Korea, Japan, the EU, Singapore and most rabies-controlled destinations require a passing titer. We confirm your country's exact rule first.
