How Much Blood is Needed on the Vitamin D Test?

  • Fill one circle at a time with 1 BIG drop of blood in each circle.The circle needs to be filled with blood.
  • If you need a 2nd drop of blood to fill out the circle, it is important that it does not take more than 60 seconds between the 1st and 2nd drop.
  • If you find it difficult to get enough blood in the circle (after 2 drops), then it´s better to drop on a 3rd drop of blood rather than to take a chance and send the test to Vitas. Just be aware that no analysis can be possible because of too little blood.
