Family Relationships, paternity, maternity, dna testing, siblingship testing, sisters, brothers, immigration DNA testingDNA Testing for Paternity isn’t the only relationship testing service we provide. Sometimes relationship uncertainty reaches to grandparents, siblings, and even mothers in some circumstances. Boston Paternity can even help determine relationships with half-sisters or half-brothers.

Accurate Grandparentage DNA Testing Services

Grandparentage DNA testing is used to determine if one grandparent or both grandparents are biologically related to a child. DNA samples from the individuals are compared almost like a standard paternity test. Boston Paternity provides accurate results to grandparentage testing in as little as 3-5 days.

There are a number of reasons for determining grandparentage:

  • Social Security Benefits
  • Estate Planning
  • Inheritance Claims
  • Immigration DNA Testing
  • Father is unavailable for testing

Whatever the reason for the test you can be certain the results you get are accurate and confidential. Contact us to schedule your Grandparentage DNA test.

Accurate Maternity Testing Services

A maternity test is similar to a paternity test. It will prove whether a woman is the biological mother of a child. DNA from a potential mother is compared with a child’s DNA. The results of the Maternity DNA test will show definitively if the woman is the biological mother. There is less of a need for maternity testing than for paternity testing. However, Boston Paternity has handled hundreds of maternity DNA tests for some of the following purposes:

  • Adoption Reunification
  • Adoption Rights Relinquishment
  • Immigration Maternity DNA Testing
  • Baby Mix-Up in the Hospital.

The key to Boston Paternity’s maternity test is accuracy. Each maternity test is run twice to guarantee accuracy.

The testing process for a maternity test involves only the mother and the child. The collection is simple and painless, and BP has a DNA collection location near you.

Sibling DNA Testing Provides Accurate Results

Many individuals are unsure about who their siblings are. No matter what reason Boston Paternity gives you accurate results for siblings. The Sibling DNA Test is a definitive way to determine biological relationships.

Boston Paternity uses the most up-to-date DNA technology to prove kinship. You have two options for sibling testing.

Full Sibling vs. Half Sibling

If you and your sibling know you share one parent but are unsure if you share the other, then a Full Sibling vs. Half Sibling is the appropriate DNA test for you. If your mothers are known and available, then they should be tested for the greatest accuracy. Boston Paternity will guide you and your sibling through the testing process from start to finish and beyond. You will be assigned a personal case manager who will schedule DNA collection appointments at a location near your home or office. View our DNA Testing Locations. The DNA siblingship test will provide you with peace of mind and the results are court-admissible if needed.

Half Sibling vs. Unrelated

If you and your sibling are unsure if you share a biological parent, then a Half Sibling vs. Unrelated is the appropriate DNA test for you. Having your mother tested will produce the most accurate results, but results can be obtained without your mother’s participation. When you call Boston Paternity to schedule an appointment you will be assigned a personal case manager. Your case manager will find a DNA testing location near your home or office. View our DNA Testing Locations. This type of kinship test will provide you with peace of mind, and the results are court-admissible if needed.

Twin DNA Testing Determines Identical or Fraternal

Twin DNA Testing will provide you with definitive proof of whether you are a fraternal or an identical twin. About one in every fifty Americans is a twin. Statistics show that two-thirds of twins are fraternal and one-third are identical.

Twin classification done at a birthing hospital is often misleading. Research shows that 25-33% of identical twins have two sets of chorionic membranes. Without a Twin DNA Test it is difficult to accurately determine whether twins are identical or fraternal. DNA results from a Twin DNA test can be used to provide peace of mind, and they can also be used to assist with future health issues. An identical twin makes an excellent organ donor.

Identical Twins

Identical twins are formed when one egg is fertilized by a single sperm cell and then divides within the first few days of pregnancy. If division of the egg occurs after 8 days, this can result in conjoined twins, also known as Siamese twins. They are called identical twins because their DNA sequence is identical. While the twins are identical genetically, this often does not apply to the actual physical or behavioral traits. Often identical twins have similar physical traits, but they can differ in some cases.

Fraternal Twins

Fraternal twins are formed when two eggs are independently fertilized by two sperm cells. Fraternal twins have half of their DNA in common, just like siblings of the same parents that are born at different times. Fraternal twins can either be of the same sex or different sex. The number of fraternal twins varies a lot in different locations throughout the world. Fraternal twins are common in the pregnancies of older women, especially common in Africans, and relatively rare among those of Asian heritage.
