# How do I provide my sample?

To provide a sample, please follow the instructions in either your "Next Steps" email from Helix or the "Next Steps" message in your online health account or patient portal (such as MyChart). 

Available labs vary by research program. Some locations may offer walk-in appointments, while others require advance scheduling. If the available locations are inaccessible to you, please email the study team (address in the Next Steps instructions) to see if you qualify for an at-home collection kit.

**Important:** If you choose to visit a lab, plan for your appointment to take about 15 minutes. Please do not provide a blood sample within 30 days of a blood transfusion or receiving blood products. If you provide a saliva sample, do not eat, drink, smoke or chew gum for 30 minutes beforehand. These activities will impact our ability to sequence your DNA and you might need to provide an additional sample.
