Toothbrush DNA testing service from a laboratory you can trust

Our laboratory’s in-house DNA scientists have undertaken viability studies to prove that used toothbrushes can be a good source of DNA. The method of brushing and type of toothpaste used has no effect on the results. Simply send us your used toothbrush and if we can get a DNA profile, we can perform a DNA relationship test in the usual way (fee applies).

When the toothbrushes arrive at our laboratory, the first step is to extract the DNA from the toothbrush. If a profile can be retrieved, the toothbrush DNA will be analysed for up to 42 DNA Short Tandem Repeats (STR) markers. If a DNA profile cannot be retrieved from the toothbrush, we will contact you and arrange to return the cost of the DNA relationship test. A refund will not be possible for the laboratory work already undertaken for the viability study on the toothbrush. 

Discreet DNA sampling method

The usual method of sample collection for aDNA test is to rub a swab on the inside of the donor’s cheek to collect cheek (buccal) cells. The DNA is then extracted from the cells when the swabs are returned to the laboratory for testing.

A major advantage of the toothbrush DNA test is that samples can be collected in a subtle manner. For example, children don’t need to be made aware that a test is being undertaken. All you need to do is simply send in their regular used toothbrush. Such a discreet method may be particularly beneficial in the case of a paternity dispute, for example, where using a swab on older children could lead to awkward questions.

Please note: This Toothbrush DNA Test is for peace of mind only, and cannot be used in legal proceedings. If you require a toothbrush DNA test for use in court, such as for a will or probate dispute, you will need a legal DNA test.

Sample collection

You can send your used, dry toothbrushes into our laboratory using the sample envelope contained in the testing kit. It’s important that the toothbrushes are not cleaned before being sent.

We can also accept electric toothbrushes: just send us the head, not the whole toothbrush.
