Collecting the genetic material from a swab can result in viable DNA samples for up to one year. Remember that both blood and cheek swabs are equally efficient when it comes to collecting the necessary materials, so always make sure you read through all instructions if you plan on using a home kit.
If the swab is properly sealed and stored in a cool and dry location, it can remain viable for up to two years or longer. In addition, if the swab is refrigerated or frozen, it can last even longer (up to five years).
The length of time that DNA lasts on a swab also depends on the type of material used to collect the sample. Different materials will have different lifespans, so it’s important to use one specifically designed for collecting samples. For example, some cotton-tipped swabs are designed with special preservatives that help them retain their viability for a longer period of time than untreated swabs.
Furthermore, the quality of the sample taken has an impact on how long it will last. If there are too few cells collected, or if they are not collected evenly across all areas, then this could affect the accuracy of results when tested at a later date. Therefore, it’s important to ensure that your samples are collected properly and with enough coverage so they remain viable for as long as possible.
Conclusion:
It’s clear that there are many factors that affect how long DNA lasts on a swab test sample – from environment and storage conditions right down to how well samples were collected initially – but understanding these factors is key in ensuring accurate results when analyzing any future tests taken from those samples. Ultimately, by taking care when conducting your own tests and storing your samples correctly you can ensure that your results remain accurate for as long as possible.
FAQ
How long does DNA last on a swab?
DNA can remain viable for up to one year if the swab is properly sealed and stored in a cool and dry location. If refrigerated or frozen, it can last even longer (up to five years).
