23andMe

If you choose the Ancestry + Health test, 23andMe is one of the few DNA testing firms that also gives you a plethora of information about your health. The health report includes information such as an assessment of your risk of developing Parkinson's or Alzheimer's disease, as well as other inherited disorders. It also provides you with "trait reports," which might tell you if you prefer sweet or salty foods.

If you only do the ancestry test, you will receive a breakdown of your family history, including your ethnic mix and the percentage of your DNA that match certain worldwide groups. Furthermore, the DNA relations tool can help you locate persons with whom you have genetic ancestors and build a family tree.

How to use:

• Your 23andMe test will arrive in a tiny kit with a piece of instructions, a plastic bag, and the sample collection tube with a funnel tip.
• To begin, create an online account and register your kit with the company.
• Fill the tube with your saliva after ensuring that you haven't eaten, smoked, drank, chewed gum, or brushed your teeth 30 minutes before giving your sample.
• Then fill the tube with buffer liquid, seal it, shake it, and send it back to the company in the enclosed box.
