Home DNA Test

Home DNA testing kits are a convenient and cheaper alternative to having your DNA sample taken and analysed at a laboratory. It is very easy to purchase these kits over the internet.

Most companies will send your home DNA test via courier so you will receive within 48 hours. The kit will include everything you need to take the sample yourself. Sample collection is usually by buccal swabs, where a cotton wad is wiped around the inner cheek, mouthwash or chewing gum. Once the sample (or samples) has been taken they will need to be send to a laboratory to be analysed. In most instances, the results will be returned within 5 working days. Where DNA testing is for the purpose of medical analysis, ethnicity testing or genealogy investigation results may take a little longer, often around 2 to 4 weeks.

The most common form of home DNA test is the Paternity test. Swabs will be provided for taking samples from both the alleged father and child. It is also recommended by the American Association of Blood Banks (AABB) that the mother be tested for greater accuracy. The cost of a home paternity test will be nearly double if the results need to be admissible in court. Necessary paperwork such as documentation for the chain of custody will be included with the test.

Home DNA tests can also be used for legal cases such as immigration application, adoption and custody battles. Always check that the home test kit you are purchasing includes the relevant paperwork to ensure it is a court admissible DNA test. You need also bear in mind that you will require unbiased witnesses to observe the taking of the samples and that two forms of identification may be required, such as a driving license or passport.

Americans can now purchase at home DNA test kits that can potentially prevent serious future health problems. The tests cost around $400 and come with the necessary instructions and equipment to take a DNA sample at home, as well as a lifestyle questionnaire. A couple of weeks after sending their DNA sample to the testing laboratory the participant should receive their results back with information about which diseases they may be genetically predisposed to and how they can make adjustments to their lifestyle to reduce the risk to their health.
