If you select a preferred testing location listed below, please be aware that not all testing centers perform all types of drug and alcohol tests. In the event that a preferred testing center selection does not offer the test you have ordered an alternate testing center closest to you will be selected. Testing locations do not accept payment and require a test registration/donor pass to conduct a drug, alcohol or DNA test. No appointment is needed, but a test registration form which will be emailed to you is required. Take this form with you or have it available on your smart phone.
