Your collection card should look like this when you’re done:
You will need to drop blood onto the left box until it collects past the first line on the right side. This typically requires about 4 drops of blood. You’ll see the card turn blue-gray. That’s the serum that the lab will test. As long as there is a large hole-punch size of serum on your card, you should proceed with sending it back to our lab.
See below for pictures of real collection cards that were acceptable for our lab.
