What is the difference between a blood DNA test and a mouth swab DNA test?
• Can hair samples be used for DNA paternity testing? • How old does the child need to be for paternity determination testing? • What if the two possible fathers are related? • What is the best sample to take from a dead body for DNA testing? • Can the presence of blood or semen be detected on an item of clothing or other materials/objects? Can it be used as a test sample? • I have a sample with a male/female mixture, but no male DNA profile was obtained from standard testing. Is there a way to obtain a male profile? • I have black hair and brown eyes. How can I have a baby with blonde hair and blue eyes? • Can a DNA test show whether twins are fraternal or identical? • Can a DNA test help me identify biological relatives? • Is there a difference in the accuracy if blood is not used? • What is the basis for population statistics in Paternity Testing? • How is DNA testing affected for Bi-Racial parents? • What is a gene mutation and how does it impact paternity testing? • How can DNA te
Difference is just in the method of sample collection. Any method of sample collection do not affect the results of DNA paternity testing in any way. A buccal swab sample is just as accurate as a blood sample. The advantages of using buccal swab collections are that they are non-invasive, painless, quick and easy. Moreover, RBCs in humans do not have nucleus. So we can not isolate DNA from RBCs. As a result we need large amounts of Blood to collect DNA containing WBCs and platelets which are relatively lesser in number.
