HOW LONG DOES DNA STAY ON CLOTHING?

DNA Testing on Clothes

Yes, DNA testing can be performed on clothing. Traces of blood, semen, or saliva are common sample types used for garment DNA tests. We will discuss these aspects further below.

How long does DNA stay on clothing?

The length of time DNA can last on clothes varies depending on how the garment has been stored. DNA on clothes can persist for days, weeks, or even years under favorable conditions.

What factors affect the longevity of a DNA sample on clothing?

The following conditions influence how long DNA can last on fabric:

• Stored clothing (Dry): DNA can last for years when the fabric is kept in a cool, dry place.
• Clothing in stored heat, humidity, or exposed to sunlight (UV): DNA degrades faster under these conditions, potentially within weeks to months.
• Washed clothing: may remove or degrade DNA, but traces can remain detectable depending on the testing method.

Can washing clothes remove DNA?

Washing clothes does not completely remove DNA. Although washing reduces the amount of recoverable DNA, traces remain on all fabric types regardless of the washing method or duration. Forensic scientists have performed a research study that produced these results. It’s important to note that the research study only used detergents, not bleach. Bleach destroys DNA to the point where a complete profile cannot be produced.

How much does DNA testing for cheating cost?
