Best at Home Paternity Test

Paternity DNA tests are becoming more and more popular and can now be purchased online. These kits come with easy-to-follow instructions for the user to perform the test from the comfort of their home and send the sample for analysis to a laboratory. The results obtained from a home paternity test are in general reliable, but when ordered by a judge, the test should be performed at the medical laboratory or health center prescribed in the court order.

This post describes the best home paternity tests available and what you should look out for when planning to buy a home paternity test kit.

What Should You Consider before Buying a Paternity Test Kit?

If you’re looking forward to buying a paternity DNA test kit, there are a few things that you should know before taking the leap.

How a Paternity DNA Test Works

The basis of paternity DNA testing (also referred to DNA fingerprinting or genetic profiling) is the DNA molecule, which determines the phenotypic and genotypic characteristics of an individual.

The genetic code contained in DNA is specific to every individual, with about 0.1% of the code sequence varying from one person to the other. Note that code sequences are identical only in identical twins, although more complex techniques have been developed​ to solve paternity and forensic cases involving identical twins as alleged fathers or originators of DNA traces. Also note that code sequences can be similar in people from the same family–​a characteristic that is exploited in paternity DNA testing.

When a paternity test is performed, the parentage and ancestry of a person can be traced. During the process, researchers identify genetic markers that permit them to pinpoint traits that are common to two persons. In the legal context, this is important as it permits a court to determine whether a person can claim to be a legal heir​ or an alleged father is (or is not) the biological parent of a child​.

Some people choose to have a paternity DNA test in case of uncertainty to have the assurance that they’re the biological father of “their” child.

Cost of the Test

If you’re on a tight budget and still wish to purchase a DNA test that gives you accurate results, it is important that you find out what a brand has to offer and whether you’re willing to pay for that.  

How to Perform the Test

Samples should be collected from all the persons whose genetic linkage is being investigated. Samples can include hair, skin, semen, blood, saliva, umbilical cord (after delivery), or cheek swab; samples collected from any part of your body can be used for genetic profiling since the DNA in all your body cells is identical.

To take a test sample from your mouth, you just need to wipe the swab around the inside of each cheek about six times on each side. You should do it firmly and gently. The process should be painless and is aimed at capturing loose cells from the inside of the cheek and not bits of the inner lining of your mouth or blood.

After collecting the sample, put the swab into the collection tube while ensuring that you don’t touch the tip of the swab with your fingers.

The samples are analyzed in a laboratory by the polymerase chain reaction and restriction fragment length polymorphism.

When to Perform the Test

A paternity DNA test can be performed either before or after the birth of the baby. Before delivery, the methods can be invasive or non-invasive. 

In the non-invasive technique, the mother’s blood is collected and analyzed to get the baby’s sample, which is then sent for DNA testing. This method can be performed as early as nine weeks into the pregnancy.

An invasive technique can be used to perform the test before delivery and is typically performed in case the paternity needs to be determined prior to the delivery of the baby.

 Two invasive techniques are used to collect samples for paternity testing: amniocentesis and chorionic villus sampling.

Both amniocentesis and chorionic villus sampling carry medical risks both to the mother and her unborn child. In amniocentesis, the physician inserts a needle through the mother’s abdomen to collect a amniotic fluid, which contains the fetus’ genetic material. Amniocentesis is usually performed after the 14th week of pregnancy and the procedure can be very costly at some medical centers. 

Some doctors do not recommend performing an amniocentesis because it carries a risk of miscarriage and prefer to perform the test after the delivery of the baby unless there’s a strong medical reason to do so. 

In chorionic villi sampling, the physician uses a needle to collect cell samples (called chorionic villi) from the placenta where it attaches to the uterine wall. The procedure is typically performed around the 10th to 12th week of gestation and has been associated with adverse outcomes, including fetal loss​. ​

Accuracy of the Test

Although paternity tests are usually very reliable, these are not always 100% accurate. There is a very slim chance that two unrelated persons can have common genetic markers (one in a billion probability). Consequently, it is typically recommended to test more than one genetic marker during DNA profiling in order to have a reliable result. Unfortunately, it is very time-consuming and expensive to test multiple genetic markers.​

Precautions to Take

Don’t perform the test within three months of having a blood transfusion if you wish to have the best result. 

If you plan to provide a mouth swab for paternity DNA testing, it is best to avoid eating, drinking, smoking, or brushing your teeth at least one hour prior to sampling. These are the best practices to follow so that you increase your chances of getting an accurate test result. 


If you’re looking for a reliable home paternity DNA test, you should be assured that the tests reviewed here will offer you the best possible results. If you have the budget, the STK Paternity test is the best option. Otherwise, you can go for the Paternity Depot – Paternity Test Kit, which is not only the cheapest option in this list, but also provides accurate results. Nevertheless, you should bear in mind that these tests can be marred by procedural delays and you might have to call the customer service of the manufacturer to follow up on your test results.
