• 1.

    Using a dried blood sample, we can collect the 100% of your DNA and analyze the genetic sequence in our lab.

  • 2.

    The sequence is divided into several parts, amplified, grouped in clusters and then sequenced.

  • 3.

    This sequencing process reveals the order of nucleotides that make up the original DNA sample.

  • 4.

    We then compare the genome with a generic and globally recognized reference DNA sequence.

  • 5.

    We have collected useful sets of quick instructions to make this device accessible to you.
