In my experience here I have spoken to thousands of customers. Many of them have wondered if a cheek swab is enough. Does blood give different data and would it be more accurate? Simply answered, no.
A more detailed explanation would be that DNA is DNA. So, the DNA that you have in your blood cells is the same DNA in the cheek cells used for DNA Paternity Testing. Having your blood sample would not give us any additional data that would be helpful in determining the results of your test.
So, if you are one of many people worried that cheek swabs don’t seem as viable as blood sample, please be assured that it is. And that your results would be the same whether we collected blood or cheek swabs.
