To determine the biological mother of your child, get this Basic DNA Maternity Test. This test gives you an accurate determination (with an average probability of maternity of 99.9%) of who the child’s biological mother is. This test is for informational purposes only and not admissible in court or for legal evidence that may be needed for documentation. The process is very simple and easy. It starts by collecting epithelial cell (skin cell) samples using a soft swab rubbed on the inside cheeks of the mouth to obtain DNA from the child and the alleged mother. A sample from the known father is not required, but can be useful. The lab will be able to determine which half of the child’s DNA was contributed by the known father; therefore, the remaining DNA must then match the alleged mother. Then the DNA of the potential mother is analyzed to determine the probability that her genetic markers are found in the child. This is known as a percentage of probability of maternity.
