Good morning! Quick question. My boyfriend wants to do DNA to our 1 year old son . However the place he recommended says they gonna take him blood and from my son they gonna take cheek swap ! How accurate is this combo ? I’m not scared of the outcome of the results because I know his the father I’m just panicking wondering what could go wrong at Lab.

Brilliant wAY 5:50 that you have explained DNA HOW WILL I KNOW IF I WILL GET TOLD ALL OF THE INFORMATION FROM MY DNA THAT YOU FIND ???

Hi Jessica, Illumina library preparation and whole genome sequencing does a pretty good job of reading all your DNA. For example in 30X whole genome sequencing, each letter of your DNA will be read an average of 30 times.

Why do some of the WGS companies (nebula for example) use cheek swabs?

[@KatharineME]

That is a great question, I would like to ask them myself. My best guess is that a swab is much cheaper than a saliva kit ($50 dollars).
