    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.

    It has been proven in most cases that blood test are more accurate but they can still glean info from saliva test. Also, some test such as DNA testing and hormone tests saliva testing is more accurate.

    For DNA testing both saliva and blood is fine.

    It depends on what you are testing for. If you are referring to a DNA test , its not actually the saliva thats tested. Its a swab of cells on the inside of your mouth, called a buccal swab. Its just as accurate as a blood DNA test and is less invasive and more sanitary.

    What are you testing for? In most instances, a blood test by all means.
