We test a range of DNA samples besides oral swabs. We always encourage our clients to use oral swab samples because these have the highest success rate and they are so easy to collect. We can test many other DNA samples including teeth, toothbrushes and finger nails but testing with such samples comes at an added cost and we cannot ever guarantee success with these samples. Why not take a look at our DNA forensic testing section and see the samples we most commonly use for a DNA test? Note the price as well as the success rate and packaging for each DNA sample.
