TestCountry's Zygosity test looks at specific genetic markers to determine the nature of the relationship between twins. It's quick and can be done in the comfort of your own home. To answer the question once and for all. Approximately one in every sixty births results in the delivery of twins. Twins are either dizygotic (fraternal) or monozygotic (identical). Fraternal twins are the result of two different eggs being fertilized by two separate sperm and resulting in two completely distinct and separate pregnancies in the womb at the same time. The DNA profiles for fraternal twins will not be identical, and they are just like full-siblings that are born at different timesIdentical twins are the result of one egg fertilized by a single sperm. The DNA profiles for identical twins will be identical. Additionally, the physical attributes of identical twins will also be similar.TestCountry's Zygosity Twin test can determine whether siblings are fraternal or identical twins or siblings. The cost of our service includes two children but you may add more as needed; like a third sibling. Parental samples are optional; if provided, paternity and/or maternity can also be verified

Instructions
Collection Methods: Buccal Swab:
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.
How to collect buccal swab:
The inside of the cheek of each person being tested is gently wiped with a soft sterile swab. Swabbing a cheek is a safe, easy way to collect the sample. Each sample is then sealed in its own envelope, labeled for identification purposes and sent to our lab for processing.
Except for infants and very young children, each person collects his or her own samples; the collection process is simple. Buccal sampling takes about 45 minutes for 3 people, with an additional 60-90 minutes for the swabs to dry.
Blood Collection:
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.
