saliva testing or blood testing?

Question

whats better and accurate?blood tests or saliva tests?

Answer 1

If you are talking about genetic testing, then any somatic cell that contains DNA will work. You can obtain those from blood, saliva, etc.

If you are talking about drug testing, then blood is still considered the gold standard, though hair analysis will detect drug exposure that occured further in the past.
