How are samples collected for a relationship test?
Relationship tests are carried out using a home sample collection kit. Once you have placed your order, we will send out your kit to whichever address you specify. If individuals are based in different locations, we can send out multiple kits to different addresses and if needed, we can also organize a couriered delivery (additional charges will apply in these cases).
Our kits will contain the mouth swabs needed for the sample collection. We include 4 swabs for every person. All 4 swabs need to be used. The swabbing procedure entails simply rubbing the swab inside the mouth and under the tongue in order to collect dead cheek cells. To ensure the DNA you collected on the swabs is preserved, you will need to leave them to air dry for around 1 hour.
When are relationship tests most often used?
Relationship tests are often used instead of paternity testing. Let us say you wish to establish the paternity of a child but the alleged father cannot be tested for some reason or other. This is where relationship tests come in. By testing the DNA of the alleged father’s relatives, for example his brother, sister or parents, and comparing the DNA of one or more of his blood relatives to the DNA of the child (whose paternity is in question), we can establish whether the untested, alleged father is really the biological father of the child.
