China Pet Titer Test: The 5 USDA-Approved Labs

TLDR: China's no-quarantine pathway requires a passing rabies titer test, but USDA only endorses results from five specific US laboratories. A titer from any other lab will not be endorsed, which means your pet defaults to the 30-day quarantine on arrival, regardless of the test result itself.

If you're preparing your dog or cat for entry into China without quarantine, the titer test lab you choose matters as much as the result. USDA only accepts results from a short, fixed list of laboratories, and a passing titer from the wrong lab still leads to quarantine.

Why the Lab You Choose Matters

China's rabies titer requirement isn't just about getting a passing number. The titer test laboratory report must accompany the APHIS-endorsed health certificate, and USDA will only endorse a health certificate when the titer comes from one of its approved labs. A passing result from an unapproved lab, including a reputable veterinary diagnostic lab that isn't on the list, does not satisfy the requirement. USDA simply won't endorse the certificate, and without that endorsement, your pet cannot use the no-quarantine entry pathway.

The Five USDA-Approved Labs for China Titer Testing

USDA limits rabies titer testing for China to exactly five US laboratories:

• DoD Food Analysis & Diagnostic Laboratory, Fort Sam Houston, TX
• Kansas State University Rabies Laboratory, Manhattan, KS
• Auburn University College of Veterinary Medicine, Department of Pathobiology Virology Laboratory, Auburn, AL
• Centers for Disease Control and Prevention (CDC), National Center for Emerging and Zoonotic Infectious Diseases, Atlanta, GA
• University of Missouri Veterinary Medicine Diagnostic Laboratory, Columbia, MO

No other lab, anywhere in the US or abroad, is accepted for this requirement. Confirm with your veterinarian before the blood draw that the sample is being sent to one of these five.

Before the Blood Draw: Scan the Microchip First

Your pet's microchip must be scanned before the blood draw for the titer test. This confirms the microchip is functioning and readable, and it links that specific blood sample to your pet's official documentation. A titer report that can't be tied to a verified, scanned microchip number creates a mismatch risk across your pet's health certificate, vaccination records, and lab report, which is one of the more common reasons paperwork gets flagged at customs.

Timing the Blood Draw

The blood sample for the titer test must be drawn on the same day as, or any day after, your pet's second rabies vaccination. Drawing it before the second vaccination invalidates the test for this purpose, even if the lab itself is correctly approved.

Once drawn and passing, the titer result is valid for up to one year from the sampling date, and that validity period must cover your pet's actual arrival date in China.

What Happens If You Use the Wrong Lab

If a titer test comes back from a lab not on USDA's approved list, the health certificate cannot be endorsed for the no-quarantine pathway. Your pet would then need to enter through one of China's designated ports and complete a 30-day quarantine at your expense, the same outcome as if no titer test had been done at all. The test itself, the cost, and the wait time are not refundable or transferable to a different lab after the fact.

Frequently Asked Questions

Can I use any USDA-accredited lab for my pet's China titer test?
No. China titer testing must go to one of five specific labs USDA has approved: Fort Sam Houston, Kansas State University, Auburn University, the CDC, and the University of Missouri. No other lab is accepted, regardless of accreditation status.

What happens if my titer test comes from a lab that isn't on the list?
USDA will not endorse the health certificate, and your pet must enter China through a designated port and complete a 30-day quarantine.

Does my pet's microchip need to be scanned before the blood draw?
Yes. The microchip must be scanned and verified before the blood draw so the titer result is correctly linked to your pet's documentation.

When can the blood sample be drawn?
On the same day as, or any day after, your pet's second rabies vaccination. It cannot be drawn before the second vaccination.

How long is a passing titer result valid?
Up to one year from the sampling date, and that period must cover your pet's arrival date in China.
