Ask The DNA Doc
Ask The DNA Doc Q and A
Q: Can a DNA test determine who the father of a child is, if the two possible fathers are cousins?
Q: What do my DNA test results mean?
Q: Can a DNA test be done using a sample from a blood glucose strip?
Q: I don't have any idea who my father is. Can I do a DNA test and compare my DNA profile to other DNA profiles found in a DNA database?
Q: I had a "blood" test in 1981 to determine my paternity. The results appear to indicate that my mother could be the alleged father's child. Could this be a mistake? Can my mother and I now conduct a blood test to determine if our samples were mixed up?
Q: I have DNA results which indicate that I am not the father of the child. Blood samples were collected from two of the tested parties while a cheek swab was collected from one of the parties. What is the possibility of these results being wrong?
Q: My brother passed away over 20 years ago. At the time, he had a 9 month old child, but was unsure of the child's paternity. That child is now 20 years old. Can we test the child and me to determine paternity? The child's mother is also deceased.
Q: Can DNA tell how much aboriginal blood a person has and from which First Nation?
Q: If a child's paternity is in question and two brothers are possible fathers, how can a DNA laboratory determine who the father is? What if only one father is tested?
Q: If DNA paternity test results indicate that a mutation is present, and there is a possibility that the true father of the child is the biological father of the tested man, what else should be done?
Q: A DNA paternity test was conducted in 1992 by blood testing. Only one of the two possible fathers was tested. The results indicated that the tested man is the father. Is there any way the test could be wrong?
Q: If the alleged father and mother are first cousins, does this affect the validity of DNA test results?
Q: Can DNA be taken from a grandmother and grandchild to determine paternity?
Q: Can blood typing be used to determine the paternity of a child?
Q: What is the likelihood of an exclusion in a paternity test when in fact the tested man is the father?
Q: My mother never told me who my father was. She has passed away, but I was wondering if it is possible to determine my birth father by just testing my DNA. Is this possible?
Q: I tested my daughter’s DNA against two possible fathers. The results indicated that one of the men is her father, but she doesn’t look anything like him. She looks like the other man. Is there a way the test can be wrong?
Q: Can a relationship be established by DNA testing between 3rd cousins?
Q: Can you use chewing gum for DNA testing?
Q: Can a DNA test be completed if the alleged father is incarcerated?
Q: If the alleged father lives in one province and the child lives in another province, can we still have the test done?
Q: If DNA testing is required to settle an estate, who pays for the test?
Q: Where can I get a DNA test for free?
Q: What if two biological brothers are both possible fathers of the same child? Do both brothers need to be tested?
Q: Would the results of a DNA paternity test be more accurate if the mother of the child was tested?
Q: My DNA paternity results say that I “cannot be excluded” as the biological father of the child. Does that mean that I am not the father?
Q: The report states that the child is not mine but my numbers match the child’s numbers. Why am I not the dad?
Q: Is it possible to get a DNA test while pregnant?
Q: How soon can a sample from a fetus be taken from a pregnant woman for prenatal DNA paternity testing?
