Shipping Policy
Last updated: July 29, 2026
Quick summary
Shipping is free both ways within the United States. Kits ship within 1–2 business days of your order and typically arrive in 2–5 business days. Your return label is included in the box. The sample is stable at room temperature — keep it out of direct sun and hot cars, and mail it back when convenient.
1. Where we ship
We ship within the United States only, and only to states where direct-to-consumer testing is lawful. See Where We Operate for current state availability. We do not ship internationally, and we do not ship to freight forwarders.
2. Cost
Free two-way shipping is included in the price of every kit. There is no separate shipping charge at checkout, and no charge to return your sample to the laboratory.
3. Processing and delivery times
Orders are processed and shipped within 1–2 business days. Delivery typically takes 2–5 business days after shipment. You receive tracking by email, and by text if you opted in to transactional SMS. Carrier delays, weather, and holidays can extend these estimates.
4. Returning your sample
Your box includes a prepaid, pre-addressed return mailer. Collect your sample following the instructions in the kit, register the kit to your account, and drop the mailer in any USPS collection box or hand it to your carrier. The sample is stable at room temperature — keep it out of direct sun and hot cars, and mail it back when convenient.
5. Lost, delayed, or damaged shipments
If your kit does not arrive, arrives damaged, or your return mailer is lost in transit, contact us and we will send a replacement kit at no cost.
