📋 Step 1: Preparation
1. Read the instructions carefully.
2. Prepare all materials: lancets, gauze pads, alcohol swabs, sample tubes (if multiple), bandages, security bag, and shipping envelope.
3. Open the email “Important for your test result: Please activate your test” as you will need it later.
🧪 Step 2: Execution
4.Remove the lid (do not twist) and place the tube in the designated cut-out (right flap) in the shipping box to prevent it from tipping over during blood collection. (see video)
5. Stimulate blood circulation: Hold your hand under warm water for at least 1 minute, dry it, and rotate your arm in large circles 5–10 times.
6. Disinfect the chosen finger with the alcohol swab and let it dry briefly. Tip: The index and middle fingers are particularly suitable.
7. Hold the blue-white lancet horizontally, twist the protective cap around its axis, and carefully remove it. Important: Do not use the lancet without or with a loose protective cap.
8. Place your hand palm up on a firm surface.Place the lancet on the center of the fingertip and press firmly. Wipe away the first drop of blood.
9. Stand up and hold the hand at a downward angle below heart level, gently massaging (!) from the palm to the fingertip. Important: Do not squeeze the finger to avoid bruising, as this can distort blood values.
10. Hold the finger over the tube and fill it (the stripping aid can be used). If insufficient blood is produced, start again with a second lancet on another finger.
11. The collection is complete when the 0.5 ml mark of all included tubes is reached. Tap the tube lightly on the table several times to allow the blood to flow.
12.Press the cap back onto the tube until a "click" sound is heard. Please ensure that the collected blood mixes well with the additive contained in the tube. Important: Less than 0.5 ml per tube is not analyzable.
13. Turn the tube 4–5 times slowly upside down to mix the blood with the stabilizer.
14. Cover the wound with a bandage.
📦 Step 3: Registration & Shipping
15. Place the sealed tube in the transparent safety bag and seal it carefully. Important: Do not tear open the safety bag!
16. Place the safety bag in the gray return envelope and seal it carefully.
17.Open the email you received in advance and click on “Activate Test” in the test profile. Follow the next steps and fill in your details so that the order can be sent to the laboratory.
18. Submit the envelope directly at a post office (no mailbox drop!), to ensure your sample arrives safely and quickly at the laboratory.
19. Once your sample has been analyzed in the laboratory, you will receive a notification and can view your results online.
