Then, samples collected by stirring cotton swabs on the inner part of cheek are delivered back to laboratory. After taking permissions of grandparent, grandchild and official parents of under 18 years old children, results of samples worked with 26 markers are ready in 7 workdays. It is not a must for grandmother to give sample; on the contrary, if she wants to give sample in order to increase the sensitivity of the test, she can give without paying any extra charge. Results cannot be used as evidence in courts.
