Buy infectious disease tests to help you identify bacterial or viral infections. After you buy your own test and schedule an appointment online, visit your nearby Quest Diagnostics location to complete your specimen sample collection for your infectious disease tests. Your lab results will be shared online as soon as they’re available. As part of your purchase, you have the option to discuss your results with an independent physician. Treatment options may be available. Please note: Results delivery and PWN services are not applicable for infectious disease at-home kits.Read MoreRead Less
