Although the methodology used is the best currently available, sometimes it can happen that the sample does not contain enough DNA and it is not possible to provide a reliable result. This may be due to many factors, such as the sampling process was not performed correctly or that the sample was not kept in proper temperature conditions before or during shipment.
In these cases a new batch of swabs will be sent without the kit box, to perform a new sampling of the patient. If the online registration was already performed previously, it will not be required again. One repeat test will be offered for free.
