Buccal swabs are an excellent source of DNA for paternity testing. Loose check sells are collected by rubbing a cotton Q-tip type swab in the mouth on the inside of the cheek. The cheek cells are an excellent source of DNA for paternity testing.
It is also common to collect blood for DNA testing. In most cases there is no advantage to collecting blood over collecting a buccal swab, and there are several disadvantages to collecting blood. Buccal swabs are painless! Collecting blood requires a minimum of a finger stick. Blood can transmit serious diseases such as HIV and Hepatitis. Buccal swabs do not have the same biological risks as blood.
The DNA from a buccal swab is exactly the same as the DNA from blood. There is no scientific advantage of using one over the other. The DNA is contained in the nucleus of the cells and it is identical in a cheek cell and a white blood cell.
Some people may not want to have a buccal swab or blood collection. They may want to perform a DNA test using anonymous samples. There are many reasons for performing an anonymous paternity test. Often the subject is very controversial and the parent does not want the child to know that they are being tested.
The DNA tests usually involve unusual items that have been discarded or household objects. The paternity test would not name an individual but may state for example:
The donor of the DNA on the tissue cannot be excluded as the biological father of the donor of the DNA from the child. Then there would be a statistical calculation relating to the likelihood that they are child and father.
Anonymous paternity testing may be used in a variety of situations. For instance, an adult child may believe that the man that raised them is not their biological father. They may not want to ask the parent or upset him. They often just want to know. It may be something that they have suspected for years and would like to know without disrupting their family. If the man is their biological father then they did not cause hurt feelings or cause trauma within the family. If he is not the biological father, then the adult child can decide whether or not to ask the parents about the situation.
A variety of items can provide adequate DNA to generate an identity profile. Very common items such as a tooth brush, plastic straw, bubble gum, licked stamps, cigarettes, baby pacifiers, and clippings from an electric razor usually provide adequate DNA for paternity testing.
It is impossible to use a sample for a paternity test that was used by more than one person. One example would be if there is any possibility that two people used the same soda straw it can not be used for the test. You may get the wrong answer! At best, the test will not be able to be completed with a sample that contains DNA from more than one individual.
Peace of mind without family disruption is the most common reason for an anonymous paternity test. Anonymous paternity tests may be requested by mothers, fathers, grandparents and adult children. - 15784
