• Unsure about your preparation? Send us a copy of your requisition and our team can help clarify the instructions.

Please bring your current medication information and any relevant medical documentation to your appointment.

For forensic or deceased-family-member DNA testing, please provide as much of the following information as possible:

• The coroner’s or medical examiner’s contact information, if available.
• The city where the family member passed away.
• Any additional information provided by the coroner, hospital, funeral home, or other authority that may assist with coordinating the testing.

Having this information available can help our team determine the appropriate testing process and coordinate with the relevant authorities when required.
