DNA Testing with special samples

 

 

 

All DNA tests offered by our laboratory can be done using non-standard samples (with the exception of the fetusSafe™ prenatal DNA test).

DNAForce understands that it is not always possible to obtain samples directly from the people that need to take part in the analysis. For example, the person might be deceased, lost or not available, etc. Consequently, it is possible to perform a DNA test using non-standard samples. Our laboratory has vast experience testing all the samples below.

Non-standard samples: Please note that due to the impossibility of determining the quality of the samples submitted prior to the analysis, the laboratory cannot guarantee the unconditional success of these types of samples. However, we operate the most up-to-date and modern laboratory equipment available and our success rate is one of the highest in the industry, this includes special samples, degraded samples or samples with low DNA count.
