Can someone else’s DNA get onto my clothes?

Yes.

DNA from another person can be transferred onto clothing without direct contact between those individuals.

Research has shown that DNA may move through handling, shared environments, and intermediary objects. Clothing can pick up biological material through everyday activities such as sitting on surfaces, contact with hands, or washing and storage with other items.

Laboratory testing can detect DNA on clothing and sometimes identify a contributor. It cannot determine how that DNA was deposited, when it was left, or whether the person ever wore or directly touched the item.

DNA may be transferred during laundering, through contact with other garments, or through handling by another person. Small amounts of biological material can persist even after movement between items.

The presence of someone’s DNA on clothing does not establish that they wore it, touched it directly, or were present when it was used. Interpretation requires consideration of transfer opportunities, prior handling, washing, and the wider circumstances of the case.
