Twin Zygosity DNA Test
The Twin Zygosity DNA Test provides a fast and accurate way to determine whether twins are identical (monozygotic) or fraternal (dizygotic). This test analyzes genetic markers from each twin to determine if they share the same DNA profile or have distinct genetic differences.
Using simple, non-invasive cheek swab collection, the twin zygosity test can be completed easily at home and delivers reliable results analyzed by an accredited laboratory.
When Should You Use a Twin Zygosity DNA Test?
This test is commonly used when:
You want to confirm whether twins are identical or fraternal
Medical, developmental, or educational information is needed
Physical appearance alone does not provide a clear answer
Accurate genetic confirmation is preferred over observation
Who Can Be Tested
Two twins
The test works for both same-sex and opposite-sex twins
No parental samples are required
Accurate Twin Zygosity DNA Analysis
DNA samples from both twins are analyzed using advanced genetic comparison techniques. Identical twins will have matching DNA profiles, while fraternal twins will show genetic differences similar to siblings.
All testing is performed at an accredited laboratory, ensuring high standards of accuracy, reliability, and quality control.
Turnaround Time
Results are typically available within 3 to 5 business days after the laboratory receives all samples.
Simple, Private Testing
Sample collection is quick and painless using cheek swabs. All testing kits are shipped in plain, unmarked packaging, and results are delivered securely to protect your privacy.
