Paternity Test

Other types of samples fot testing

The most conventional and easiest sample is the buccal swab however it's not always possible to have a sample of the buccal mucosa, for this reason Gentras has other type of testing available to its clients

In the following chart we show the success probability of the various samples. All the samples in this chart can be tested in our laboratories. The only difference is the success probability and the additional cost for the DNA analysis which depends from the type and condition of the sample

Should you have any queries please don't hesitate to contact us.
