What is DNA
Every cell in the body contains a complete set of DNA. It can be found in our blood, our hair, our skin, our semen and even our bones.
DNA, deoxyribonucleic acid is a complex chemical structure that is unique and different for every organism. DNA is the basic building block of the Genome. A complete set of DNA is called a Genome. You could also say that genome is made up of DNA. Chromosomes are the containers of proteins and DNA.
Two common ways to test DNA are Restriction Fragment Length Polymorphism (RFLP) And Polymerase Chain Reaction (PCR) Using Short Tandem Repeats (STRs). All organisms have different number of chromosomes. Humans have 23 pairs of chromosomes that are inherited from our parents. In each pair of chromosome, one is from our father and the other from our mother.
Why is DNA test required?
DNA test is done to compare the DNA profile of two or more individuals. It confirms a biological relationship between two people. The need may arise to prove identity, paternity or in crime cases. It also helps to trace our ancestors.
The DNA of an unborn child can also be tested. The test is also done for custody cases.
Purpose of getting a DNA test done
Immigration- DNA test can be used in immigration process to prove that genetic relation and biological bond exist between the two parties. Certain countries have rules for this. You need to prove your relation and then only the visa is issued. In these cases the court may also demand reports of DNA test. The USCIS, U.S. Citizenship and Immigration Services usually order the applicants and the sponsor to submit DNA test results to prove that there is a biological bond between the two. Many other countries want DNA test as a proof of relationship, when no other document is valid. An immigration DNA test is a way to unite with your dear ones. But The DNA tests, which are performed at home through home-kits, are not considered as valid evidence in immigration cases.DNA testing is useful when no other form of credible evidence is available for immigration visa application.
It is successful if you want to know if there is any chance of disability in the genes. This is in case of adoption where the whereabouts of the parents are not known.
If you would like to know about your family history then you should go in for Ancestry Testing services. Through a simple DNA sample you will be able to trace the history of your ancestors and where they originated from, as well as obtaining a record of their movements throughout the ages. DNA can bring you closer to your past.
Tests for mental peace
Super paternity test, sibling DNA test, maternity test, grand parentage test, DNA profiling, twin zigosity test, Y-STR testing, etc. the availability for non invasive prenatal paternity and Prenatal maternity (surrogate mother)test are also available.
Highly advanced prenatal tests are performed during pregnancy to verify the paternity of the developing child. The accuracy level of this test is more than 99.99 %. The sample of the mother’s blood is required and also the blood sample from the alleged father. Sometimes the alleged father does not agree to give a blood sample. In this case, discreet samples like toothbrush, rooted hair, skin, semen etc. can also be given.
The most common way of testing DNA is by buccal swab. These can be done at home. The buccal cells, from the inside of a person’s cheek can be collected. This can be done using a buccal swab or a cheek swab. These swabs have a synthetic tip and a wooden or plastic handle.
To see if two children share one or both parents, a sibling DNA test is conducted.
DNA maternity test can be conducted to know if the woman is the biological mother or not. As in case of paternity test, maternity DNA Test compares the child’s DNA with that of the alleged mother.In certain cases, the father disagrees to undergo the test or is unavailable; the alleged grandparents can undertake the test. This will determine if they are the biological grandparents of the child. This is the grand parentage DNA test.
If required you can consult your laboratory for free consultation. The results are reliable and affordable. Some laboratories also give payment plans for the test. Results are also available in a short time say a week.
