Types of DNA Tests Available


Non-Legal Paternity DNA test

Non-legal Paternity DNA Test for personal Information use, also known as the “peace of mind” DNA test, assists in determining whether or not a specific man is the biological father of a specific child by comparing both the alleged father and the child's DNA profiles. Paternity testing entails obtaining and analyzing the DNA of a small sample of cells from the inside of the cheek.


An individual's DNA serves as a "genetic blueprint," and, like a fingerprint, is unique to each individual. When the sample is taken, the DNA is extracted from the cells and amplified using a technique known as PCR (polymerase chain reaction), which amplifies specific regions of the DNA. These amplified regions are examined carefully for a DNA pattern. The DNA pattern of a child is compared to that of the alleged father. Because both biological parents pass on their genetic information to the child, comparing samples of DNA patterns from the child and the alleged father will conclusively determine whether the alleged father is the true biological father.


Legal/court admissible Paternity DNA test

The Legally Admissible DNA Paternity test is intended for court use and is accepted as legal proof of paternity or non-paternity in court. This option is most commonly used for the purposes of paternity claims, child support, child custody cases, immigration, social security or disputes over inheritance. A legal paternity test also can be used for adding or changing a name on a birth certificate. Optimal Lab Test adheres to AABB guidelines for a legal chain of custody sample collection protocol. When choosing legal paternity test, a chain-of-custody sample collection process will be used during the collection in order to ensure proper identification, witnessing and fingerprinting of the parties involved.

Please remember to bring an identification such as a driver’s license, passport, National ID card, or military ID. In the case of any children being tested, a valid and certified birth certificate copy may be requested.


Non-Legal Maternal DNA test

Non-legal DNA Maternity Test is a premium DNA test which conclusively determines whether a female is the true biological mother of a child. If you choose the private test option, a painless buccal swab (mouth swab) collection kit will be sent directly to you for sample collection in the privacy of your own home. The sample is collected by rubbing the swabs gently inside the mouth against the cheek.


Legal Maternal DNA test

Legal Maternity DNA Testing helps to determine a relationship between a biological mother and child. All children inherit half their parent’s DNA. 23 chromosomes from the father and 23 chromosomes from the mother. A DNA test analyzes a mother contribution to her child even if the biological father is unavailable.

Legal Maternity DNA Testing follows a strict chain of custody collection process similar to Legal Paternity DNA Test.


Pre-Natal Non-invasive Paternity DNA test

When waiting to determine the biological father of your child is not an option this alternative may be for you – a non-invasive Prenatal Paternity Test with zero risk to the fetus. This non-invasive test determines who the child's biological father is (with 99 percent or greater certainty) as early as 7 weeks of pregnancy and eliminates the risk of miscarriage.

Optimal Lab Test’s trained collectors will take a sample of maternal blood (collected via arm like any blood test at the doctor’s office) and mouth swab samples from the alleged father. A certified AABB Accredited DNA Lab Scientists will analyze the mother’s blood sample and isolate fetal DNA from the plasma. The fetal DNA is then analyzed against to the DNA of the alleged father to see if there is a biological relationship.

An analysis of the fetal DNA and the mother's DNA can aid in determining the precise "genetic markers" contributed by the father. The potential father's DNA is then analysed to determine the likelihood that his genetic markers will be found in the child.


Grandparent DNA test (Legal & Non-Legal)

A grand parentage DNA test is used to determine a genetic family relationship between a possible grandparent and a grandchild, or to establish paternity if the child's alleged father is unavailable for testing. The genetic profile of the alleged father can be reconstructed by analysing DNA samples obtained from his biological parents. To achieve the best results, the mother of the child and both alleged grandparents should be tested.

True biologically related grandparent/grandchild pairs should have a grand parentage index value greater than 1.0 in their DNA Grand Parentage Test Report. Individuals who are not grandparents/grandchildren should have a grand parentage index value less than 1.0.


Immigration DNA test

Immigration DNA testing is a paternity, maternity or kinship test that is conducted at the request of the U.S. Embassy, Department of Homeland Security, or United States Citizenship and Immigration Services (USCIS). When this option is taken, immigrants are often required to submit to DNA testing in order to prove their relationship status with the person who is sponsoring their visa. U.S. immigration authorities commonly require immigration DNA testing for immigration clearance, granting citizenship, and even passport verification.

In such cases, the accuracy and timeliness of your DNA test results are of the utmost importance.


Infidelity DNA Test

When it comes to suspected infidelity, you're probably feeling uncertain, hurt, and confused. These are frequently extremely complicated and emotionally charged situations. When you suspect a loved one of being unfaithful, it can be difficult to know what to do. A simple DNA test can be a very helpful tool. Our infidelity DNA testing allows you to determine the definitive, indisputable truth so that you can make the right decisions about yourself and relationship. At optimal lab Houston, we understand that such situations are extremely important and thus we keep your test results confidential, accurate and efficient.


Siblingship test (Legal and Non-Legal)

A DNA sibling test will test the relationship between two or more individuals to assess if they are biologically related as siblings. Sibling tests can also be used to provide reliable parentage testing when one parent is deceased or unavailable. Usually siblingship DN test are of two types. One is Full Siblingship Test and other one is Half Siblingship Test. Full Siblingship DNA test is a test between siblings that shares both parents. Half sibling DNA test between siblings that shares a common parent. Both sibling DNA test can be used to submit evidence to immigration (USCIS, U.S. Embassy) or, this option can be used for adoptees as well.
