Paternity Test

DNA Test performed to determine the biological father of a tested child. Paternity may be verified using methods of hair follicle tests, buccal swab, or blood test. We can perform this test in our office or mobile services may be available.

Maternity Test

Maternity DNA testing determines whether a woman could be the biological mother of a child. Like a DNA paternity test, it compares a childs DNA pattern with that of the alleged mother to determine how likely it is that the child has inherited the DNA from the alleged mother

Grandparent Test

A grandparentage DNA test determines whether a couple could be the biological grandparents of a child. It is an indirect way to determine family relationships when an alleged father is not available for a paternity test. Grandparentage test results may be used as proof in Social Security benefit and other inheritance claims as well as in some immigration cases. In the test, the childs DNA profile is compared with the DNA profiles of the alleged fathers biological parents. Since a child inherits half of his/her DNA from the mother (maternal side) and half from the father (paternal side), the paternal half should match DNA passed down from the alleged grandparents. The mothers participation is encouraged to expedite analysis; motherless grandparentage tests take longer to complete because of the extended analysis required.

Sibling Test

A siblingship test is a DNA test conducted to determine if two children share one or both parents (i.e., if they are half or full siblings). It is an indirect way to determine family relationships when an alleged father or mother is not available for a paternity test. Results of a siblingship test may be used as proof in Social Security benefit and other inheritance claims.

Profile Test

Our DNA profiling service allows individuals to obtain a record of their genetic profile a unique combination of 16 markers found in their DNA that serves as a permanent genetic ID. Organizations and private individuals choose to obtain records of their DNA profiles in case identification is ever needed, as in the following examples: Future paternity tests in case of claims on a person's estate To provide a standard for comparison and identification of people in high-risk professions, such as men and women in the military, law enforcement personnel, firefighters, and overseas contractors To assist with the identification of missing persons To give clues about the trail of a missing loved one

Twin Test

During OB-GYN visits, the physician might be able to tell whether twins are identical or fraternal through ultrasound examination of the placenta. When the twins are born, pathological examination of the placenta can also be done to determine zygosity. However, studies have shown that both methods are not 100% accurate, and scientists recommend DNA testing to determine zygosity. There are also many cases in which medical records regarding zygosity have been lost, or doubt may have arisen because of the twins physical characteristics as they grow up. In such cases, only a DNA test will be able to reveal the truth. A twin zygosity test compares the twins DNA profiles to see whether they match an exact match proves that the twins are identical. The results of a twin zygosity test may be used to satisfy personal curiosity as well as to help solve health problems for the twins later down the road. For example, in the event that a twin needs an organ or tissue transplant donor, the identical twin is a perfect choice
