Please follow the steps below to properly collect a sample using 3billion’s DBS:

Step 1

  1. Clearly write a patient's 3billion ID and date-of-birth(DOB) on the right section.

Step 2

  1. To avoid contaminating the card, carefully open by holding the left bottom corner colored black.

Step 3

  1. Apply at least 1.2mL of whole blood to the card by filling all 6 spots and 10 strips.

Step 4

  1. Place the card vertically on a flat ground as shown in the picture and allow the card to air-dry at room temperature for at least 2 hours. Do not force-dry the card by heating or cooling.

Step 5

  1. When the card is completely dried, fold it back and place it inside the biohazard bag provided. Seal the bag tightly and place it in the shipping box.
