A DNA twin test is used to determine whether a set of twins are identical or fraternal. The DNA from each participant is extracted from the cells and then amplified using a technique called polymerase chain reaction (PCR) for further analysis. This amplified DNA is then analyzed using a method called Short Tandem Repeat (STR) analysis, which captures the genetic information for each marker. This data is then used to conclusively determine whether the two individuals are identical or fraternal.
Yes, the kit can be split and the sample collection components sent to each address separately. The collection components are individually barcoded, and will be tested together once the samples arrive at the laboratory. To order a split kit, please write the following into the Order notes box of the online order form “Please split kit”. Please also indicate the name and address to send each component. For example, please state “send the Alleged Father’s portion to… (specify name and address)” and “send the Child’s portion to… (specify name and address)”.
No. The DNA twin tests can be performed on individuals of any age, even newborns. If the patient is a minor, the legal guardian must sign the DNA twin testing consent form.
If the mother already knows that she is the biological mother of a child, then there is no need to test her if only the alleged father is in question. A conclusive answer can be obtained without testing the mother.
All DNA test kits are stored at room temperature before and after sample collection.
No. Test kits can be stored indefinitely prior to sample collection. Test kits should be returned for testing within 3 months after sample collection.
DNA is collected by rubbing a brush gently inside the mouth against the cheek for 15 seconds. The collection is safe and painless.
