Choose your free tests, find a participating donor center, and book through Goodlabs. At your visit, the center will screen you, collect your blood donation and separate tubes for your Goodlabs tests, and send you home with a well-earned snack. We’ll post your test results in your Goodlabs account.

Yes. Tests marked free in the donation flow cost $0 when you complete an eligible donation. No subscription or doctor needed. Choose from premade panels or individual tests.

Yes. Book through Goodlabs so your donation and free tests stay connected. Use the walk-in option only when Goodlabs offers it for that location. An appointment booked directly with the donor center will not include Goodlabs testing.

Plan for about 45–60 minutes for check-in, screening, the donation, and a short rest with snacks. The blood draw itself usually takes about 10 minutes.

Do not fast. Eat a healthy meal 2–3 hours before your visit, drink an extra 16 ounces of water, get a good night’s sleep, and wear sleeves that roll above your elbow.

Most results arrive in your Goodlabs account within 2–6 business days. Some tests take longer, so results may appear in batches. We’ll notify you as new results arrive.
