USDTL is a business-to-business specimen testing laboratory and does not perform specimen collections. Collection sites collect specimens for testing in their communities; they are independently owned and operated businesses and are not affiliates of USDTL. Collection sites in this directory offer at least one type of USDTL testing, but do not necessarily offer all USDTL testing options. It is advised that you call individual locations to ensure they offer the specific testing you need.
