Our DNA test kits come in two collection formats:
Buccal: Buccal is the "Cheek Swab" Test. A buccal swab is soft and resembles a large Q-Tip. It is used to collect a sample of cheek cells by simply rubbing the inside of the cheeks. It is as accurate as blood, as the DNA is the same. A person should, however, abstain from drinking coffee for a few hours before taking a sample, and smokers should rinse and brush their cheeks with a toothbrush before swabbing.
Blood: If you're considering the blood option, it is quite important that you contact your physician for the collection of blood samples for children under 8 years of age. We offer this option because it is much faster and easier for you to collect. The procedure involves a small lancet that is used to lightly pierce a finger (most don't even feel it). A small drop of blood is then transferred to a collection card - that's it.
Each item is listed above. To order or get more detail on the product, please click on the relevant picture.

Zygosity defines the differences between twins. Basically there are three types of twins which include Fraternal Twins, Fraternal Twins and Polar Body or Half-Identical Twins. These three basically differ on the percentage share of their genetic markers. For instance, fraternal twins share 50% of their genetic markers which make them less look-alike with other. Identical twins share 100 % of genetic markers that is why they are similar in all things including DNA patterns. Polar Body Twin share 75% of genetic markers. Although they can be identical, they may have dissimilar type of blood or DNA patterns. Zygosity is determined through zygote testing. Out of parent’s curiosity or clinical requirements.
Laboratories may perform this by obtaining DNA samples from the twins through buccal swabs or blood samples and comparing DNA patterns between samples. The prices and discounts vary between laboratories, but an accredited laboratory is a good choice.
