Security Note

Please note that we are aware of spoofing activities occurring in which individuals/organizations not associated with Sonora Quest Laboratories are deliberately falsifying the information transmitted to your caller ID display to disguise their identity. Spoofing is often used as part of an attempt to trick someone into giving away valuable personal information so it can be used in fraudulent activity or sold illegally. U.S. law and FCC rules prohibit most types of spoofing. If you receive a phone call in which Sonora Quest Laboratories appears on your called ID, we recommend that you confirm who you are speaking with prior to providing any personal information. Additionally, please visit for additional information and guidance, as well as to report any fraudulent calls you may receive.
