Men have one X chromosome and one Y chromosome, while women have two X chromosomes (and no Y chromosome). Men inherit their X chromosome from their mother. Women inherit one from the father and one from the mother. Therefore, the X Chromosome Test can be useful to verify different relationships, on both the paternal and the maternal side.
The price indicated above is the final price for the analysis of 2 people with standard samples. If the mother's sample is needed, it will be tested at no additional cost (for 1 mother, standard sample).
If you are unsure about whether this test is the best testing option for your case, please contact us. Please remember that, if there is a blood relationship between the fathers/mothers, this analysis may not be the adequate procedure for you; please, contact us before ordering your kit.
We can test other types of biological samples if you cannot send a mouth swab. Send us an email requesing a list of the non-standard samples we currently accept.
If you are in a big hurry, and can't wait for the kit to be mailed to you, you can request the paperwork for your DNA test. Fill in the forms and mail in samples taken by a cotton bud.
