Although generally viewed as safe, nasal swab testing is not without risk. Individuals performing self-administered tests with minimal training are understandably at a much higher risk of injury than those tested by well-trained medical staff. This case demonstrates the possibility of intracranial injury when a test is improperly performed, with potentially devastating consequences, including CSF leaks, encephaloceles, and meningitis. At-home tests should include materials such as written explanations, illustrations, photographs, and/or video to demonstrate proper technique and provide for e safe and adequate testing.
