For: ,

Quest Diagnostics Test Code: 5789

Rabies is a viral disease that affects animals and humans and causes massive inflammation and swelling in the brain and eventually death. The virus is spread from the bite of an infected animal which has not been vaccinated. It is important to administer the vaccine prior to the start of symptoms. This test measures a quantitative level of rabies neutralizing antibodies in the blood. These antibodies are the sole protection against death by rabies infection. This test is useful for measuring the host immunity to rabies and assess the need to booster vaccination.

This test is performed in following conditions such as:

• If you’ve never had a rabies vaccine
• If you have been bitten by a wild animal
• If you are bitten by an animal which has not been vaccinated
