Using the sample of amniotic fluid or a chorionic villi sample (CVS) from the mother and a biological sample from the alleged father (hair, toothbrush, razor, etc.) it is possible to test for the relationship between the baby and the father.
Invasive Prenatal Paternity Test (Amniocentesis test and CVS)
There are 2 types of Invasive Prenatal Paternity testing. One is to test the fetus that has been excised during an abortion surgery, and the second is to test the amniotic fluid from the amniotic sac or chorionic villi from a small sample of the placenta.
For an amniocentesis test or CVS (Chorionic Villus Sampling), the procedure for sample collection is done at an additional fee, usually around 100,000 yen. As there is risk of damage to the fetus there are not many obstetrics and gynecologists that will perform the procedure for the purpose of paternity testing. Generally it is more accepted to perform this method when testing a sample from a fetus that has been aborted or lost through a miscarriage.

Content of a Amniocentesis test
• Using the sample of amniotic fluid or a chorionic villi sample (CVS) from the mother and a biological sample from the alleged father (hair, toothbrush, razor, etc.) it is possible to test for the relationship between the baby and the father.
• It is possible to do an amniocentesis test from the 10th week of pregnancy on. You can check how far along you are in your pregnancy at this website.
• A DNA Sample Kit will be sent to the address provided within 1 business day of payment confirmation.
• Bring the kit with you when you go to have your sample collected at a local hospital. Enclose the samples in the containers provided and mail them back to our laboratory for testing.
• If you choose the Express Test Results option when you place your order, the test results will be delivered to you within 5 business days of the date we receive your samples. (Standard processing time is 10 days)
Amniocentesis/CVS Test Accuracy
• We guarantee either a result of over 99.99% probability of paternity (affirming the parentage) or a negative result completely excluding parentage.
• Theoretically, it is not possible for a DNA test to result in 100% probability
• If there are two or more alleged fathers and they are closely blood-related (brother, father) it is best that all alleged fathers be tested for the most conclusive results.
• Rest assured as DNA testing can definitively determine biological relationships.
iconYou can trust seeDNA
• A variety of non-standard sample types from the alleged father can be tested.
Please see our`What Can be Used as a Sample?`page to see what types of samples can be tested.
• We recommend consulting with your doctor beforehand as it may take some time to find an obstetrics clinic that will be able to collect a sample for amniocentesis or CVS.
With an invasive prenatal paternity test there is a risk of harming the mother and baby in the procedure, and there are additional fees of 90,000 ~ 150,000 yen for the sample collection. For testing that poses no harm to the mother or child, our company recommends the Non-Invasive Prenatal Paternity test method which is done with just a blood sample from the mother.
If a test is unsuccessful and a definitive result cannot be obtained, we offer to do a free re-test and cover all postage fees for new samples.
If the re-test still cannot yield a definitive result, we can give a partial refund of the original testing fee. Please click ＜Free DNA Re-test and Refund Policies＞for a detailed outline of our refund policies.
• A POP (probability of paternity) of 99.99% does not mean there is a 99.99% chance of a biological parent-child relationship and a 0.01% chance of no relationship. It signifies a biological parent-child relationship with an unlimited probability close to 100% (as a perfect 100% result is theoretically impossible).
What Can be Used as a Sample?
DNA Tests typically use buccal (cheek) swabs as samples for DNA analysis.
We also accept a variety of non-standard samples that contain cells for DNA extraction. Please refer to the chart below for examples of accepted sample types. If a test is unsuccessful and a definitive result cannot be obtained (not enough DNA could be extracted, sample was in poor condition), we offer to do a free re-test and cover all postage fees. If the re-test still cannot yield a definitive result, we can give a partial refund of the original testing fee. Please click ＜Free DNA Re-test and Refund Policies＞for a detailed outline of our refund policies.
