The FBI is warning people to beware of potential fraud schemes related to antibody tests for COVID-19.

Fraudulent and unapproved COVID-19 antibody tests that can potentially give false results are being marketed. Perpetrators often use the scams to steal personal information for identity theft.

The FBI recommends checking the FDA’s website at fda.gov for a list of approved antibody tests and testing companies, and consulting a primary care physician before undergoing at-home antibody tests.

Fraud can be reported by calling (866)720-5721, or visit justice.gov.
