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.
