HomeDNA has the simplest DNA extraction process; just swab each cheek twice with a cotton swab, and place the swabs in the included envelope. The National Geographic Genographic Project sent a scraper that you use on each cheek for 45 seconds, and then place in a vial with stabilizing liquid. MyHeritage DNA has a similar process. 23andMe and AncestryDNA require that you spit into a tube up to the fill line (harder than it sounds), and ship it back with stabilization liquid. Most of the services said not to eat, drink, or smoke for 30 minutes to an hour prior to testing to get the best possible sample.
DNA Clinics will always advise an appointment for your DNA test. However, there are occasions and circumstances when our customers prefer to collect their own mouth swab samples for DNA testing. DNA Clinics self-collection DNA testing kits are available to order by telephone by calling 0800 988 7107 or on-line at www.homednapaternitytest.co.uk. DNA test kits ordered on-line are sent out for FREE. The payment for your chosen DNA test is payable when you return your samples to DNA Clinics.
McCartney says that anxious people often contact her, saying they wished they hadn’t done the tests. “These companies often say that it’s worth it for the helpful advice. But I can give you really good advice right now without seeing a single test result: be active, have lots of social networks, do work you enjoy, try not to smoke or drink too much, don’t be overweight or underweight, eat lots of fresh fruit and vegetables. Nobody needs to get tests done to get that kind of basic lifestyle advice.”
