Answers to what people usually want to know.
Finger prick instructionsFull instructions with visual guidanceAfter ordering we ship the collection kit to your home. You prick your fingertip, collect a few drops of blood, return it in the envelope, and receive your result digitally by email.
A small prick on your fingertip lets you collect a few drops into a tube. The instructions include step-by-step photos and video, so no guessing required.
Usually 2 to 5 working days after the lab receives your sample. You get an email with a link to your digital result, including explanation per value.
Some people find the fingerstick tricky at first. Warm your hands, hang your arm down, and prick the side of the fingertip for better blood flow. If it still doesn't work, get in touch.
In the included return envelope with free medical shipping. Drop it in the mailbox; the lab processes your sample as soon as it arrives. For some tests it's important to send it the same day — the instructions make this clear.
Feel free to contact us via WhatsApp, email or phone. We're happy to help you before, during or after your test. If the collection doesn't work, we'll arrange a solution or send new materials — no hassle.
