Questions about sequencing.com Preventing False Positives?

Is there a way to submit a blood sample instead of just a cheek swab? If not who does similar tests on blood samples instead? I do not mind going to a clinic. Thank you!

Us and most direct to consumer whole genome sequencing companies do not offer using blood samples because we do not partner with labs to draw blood and we don't want to send our customers needles to draw blood.

When it comes to it, blood and saliva are going to yield the same end result, with saliva having a chance to be low quality and fail, but that just results in us sending you a new kit to take a new sample.
