Does DNA Wash Off In Laundry?

Category: Forensic DNA Testing

DNA can be transferred innocently by the laundry, even after clothes are supposed to be “clean.” One study discovered that when undergarments are washed with sheets containing bodily fluids, the undergarment too will have DNA on them. DNA was recovered from all fabric, regardless of washing time or method. The denim/rayon blend yielded the highest DNA recovery in all washing methods and times. Wool and the wool/rayon blend yielded the least DNA recovery in all washing times and methods.
