Try to avoid junk food and alcohol the night before taking your sample and drink at least two glasses of water half an hour prior to it.

Place the contents of the GlycanAge kit on a clean, flat and dry surface. Avoid touching the filter paper of the blood collection card. Have the plaster and a clean tissue ready to hand.


Wash your hands with soap and water, then dry. Prepare a plaster and have a clear tissue ready.


Warm-up your fingers by rubbing your hands together for about 20-30 seconds. Wipe the selected finger (preferably middle or ring finger) with the sterile alcohol swab and let it dry.


Twist off the top of the lancet. Press it firmly down on your finger (preferably the outer centre of your fingertip). After a few seconds, a drop of blood will appear.


Without touching the card with your finger, apply the blood drop to the centre of a circle on the blood collection card. Do not press the finger against the collection paper. Apply at least one drop of blood per circle to ensure sample quality.


Ensure all collection circles are filled - wait for a large drop of blood to form up between each attempt and add a second one if needed. Avoid “milking” the finger as this will speed up clotting and slow down the bleeding.

If the flow stops before you were able to fill in all circles, you will need to re-pierce with the spare lancets provided.


Leave the blood collection card to air-dry for 2 hours before enclosing back into the plastic bag with desiccant provided. Make sure to write the date of your sample collection underneath your unique GA code on the side of the blood collection card.


Place only the plastic bag with blood collection card and desiccant in the pre-paid envelope provided and post the same day in any post box. Please, ideally keep in the fridge until you are ready to post. Please safely send it to the S-Cell (Address: 3/F Crawford Tower, 99 Jervois St, Sheung Wan, Hong Kong). You can choose "Cash on Delivery" through SF Express.


Your results will be ready up to 4 weeks after your sample has been received in the lab.
