Twin Testing
Curiosity Twin Zygosity Test
A Curiosity or "at-home" Twin Zygosity test involves the collection of painless cheek swab samples in a non-clinical setting, most often "at home". Orchid Cellmark provides self-contained kits with easy-to-follow instructions, for at home collections. There is no requirement for a third party site to collect the samples. The results of a curiosity test are accurate and reliable however since samples are self-collected and there is no chain of custody, the final report cannot be used in a legal matter. The results are for the use of the tested parties only.
Court Ready Twin Zygosity Test
A court ready DNA paternity test involves the collection of painless cheek swab samples by an unbiased, third party specimen collector. Orchid Cellmark has an available network of over 5000 sites nationally. The procedure also involves a strict Chain of Custody procedure which includes:
- Verification of government issued identification
- Obtaining of a fingerprint
- A photograph of each tested party
The results of a properly administered court ready test can be used in any legal matter or to change the name on a birth certificate. The results of a court ready twin zygosity test will indicate whether the tested individuals are monozygotic or dizygotic.
