Statutory Regulatory Framework
The Fluorescent Antibody Virus Neutralization (FAVN) or RNATT rabies titer test measures neutralizing antibodies in blood serum. Rabies-free and strictly controlled countries enforce mandatory post-blood draw observation periods before entry: 90 calendar days for unlisted countries entering the EU, 180 days for Australia and Japan, 30 days for Hawaii, and 3 months for New Zealand. The clock starts on the day the blood sample is drawn by your veterinarian.

Frequently Asked Questions
Does the titer waiting clock start on the blood draw date or the report date?
The waiting clock strictly starts on the exact date the veterinary blood sample was drawn, as recorded on the official laboratory submission form.
What happens if my pet scores 0.48 IU/mL on the FAVN test?
A score below 0.50 IU/mL is an automatic failure. You must administer a rabies booster shot, wait 21 to 30 days for antibody titers to rise, and draw a new blood sample, which resets the entire waiting clock.
How long is a passing rabies titer test valid for international travel?
For the European Union, a passing titer test is valid for the pet's entire lifetime, provided rabies booster vaccinations are kept up to date without any lapse. For Australia and Japan, the test is valid for 24 months (2 years) from the blood draw date.
