RAZORS FOR DNA TESTING

Shaving razors contain white tipped hair follicles that get deposited during shaving. Disposable razors may contain blood- like material or dead skin cells while electric razors may contain hair like debris and skin like material deposits. Razors are ideal for use in the absence of an individual or for discreet testing. However, their success rate is low (~50%), samples may be contaminated due to use by multiple persons, and the DNA yield is not as high as that of buccal swabs or blood samples.
