Twin Zygosity DNA Testing
You can order a twin zygosity testing kit online, and it comes with four oral collection swabs along with clear instructions. Here’s how the zygosity testing process works:
- When the kit arrives, take two of the swabs and gently rub it on the inside of each of your child’s cheeks. Keep doing this for about 15-20 seconds, making sure to collect enough cells from their mouth on the swab.
- Allow the swabs to air dry, and then place them carefully into an envelope. Don’t forget to write your child’s name on the envelope for identification.
- Send the envelope with the oral swab kit back to our lab, and we will analyze the samples in our laboratory.
- You should receive the results of the DNA test in one business day. You will receive the results in a PDF that can be printed for a permanent copy, by email,.
