We test a whole range of samples. Oral swabs are just the most common sample we test and the one we always encourage our clients to use simply because the sampling is painless, DNA sample extraction is more simple and the price is lower. But in some cases, it is impossible for our clients to provide oral swabs samples and we can, in such instances, suggest testing with other DNA samples. Take a look at our DNA forensics section- take special care to note the success rate for each sample as well as the added cost.
