Saliva DNA testing: is it more or less reliable than other tests?

As you may know, performing genetic tests in a specialized laboratory requires taking a DNA sample from the subject. In many cases, taking a sample is not as bothersome and sometimes painful as taking blood, but it is possible to perform a DNA test with saliva, hair, or other types of analysis. One of the questions that may arise is whether all these types of samples are equally effective. The truth is that a person’s genetic code is exactly the same in all their cells, so whatever biological sample is taken from the same individual, it will not vary. Another question you may have is whether cells last once a sample is taken for, for example, a DNA test with saliva. With the means that LabGenetics provides, your cells will be perfectly isolated, thus avoiding any type of deterioration.

The most reliable test

Two great advantages accompany the DNA test with saliva. First of all, there is its reliability, since the error rates are minimal in the vast majority of genetic tests performed with this type of sample. The other is its simple and painless extraction, since it is enough to pass the swab that we also provide you through your oral mucosa. However, if the results of the DNA test with saliva are so reliable, why can we ask you for another type of sample in some cases? The answer is purely technical, since the analyses we perform may require other biological samples to speed up obtaining results or further specify their reliability. Whatever the sample requested, the security of LabGenetics in all its processes has made it one of the leading genetics laboratories at a national and international level.
