To test the DNA source is here
You can not see a crime drama on TV or news (which Anna Nicole Smith) much today time without hearing about DNA. DNA testing can tell who is the father of a child. You can rescue a prisoner from prison or innocent to prove a case against a criminal. DNA testing can give you an idea of some diseases that are more prone to develop others. DNA You can also connect with their ancestors and show you where could have originated.
But what is DNA? Deoxyribonucleic acid is a kind of template for all cells in your body. Genes made of DNA. You get half your mother, your father and half. The only two people can have identical DNA are identical twins. In other cases, DNA is a genetic fingerprint itself. Because it is unique, police and prosecutors seek DNA samples to help catch and convict criminals. In the system Legal, DNA samples should be handled with care.
But people can make their own DNA tests in the privacy of their homes. A blood sample is not necessary. It only takes a few cells from the lining of the cheek. A scraping of the mucosa taken with a swab is sufficient for DNA testing. It is the most commonly used to determine paternity.
The test kit can be ordered online or purchased at the pharmacy. The cost of a simple paternity test runs between $ 100 and $ 250. You take your own sample and send lab. If you try to establish paternity, you also need a cheek swab possible father and the child plays. More labs say they do this test I can say with accuracy above 99% if the respondent is the father of the child, and 100% if it is not.
There are also ways to get possible father's DNA surreptitiously. Sometimes laboratories can test a piece of gum, or hair. Each laboratory is different, and hundreds of samples less-than-perfect cost of dollars more to try.
What can be done at home? You can test other family relationships, if there is a problem. You can also to test their DNA to see their ancestors. The National Geographic Society is even collecting DNA samples from around the world to create a kind of genetic map of the world. You can participate by conducting a DNA test at home, which costs about $ 100.
Some other types of home DNA tests are probably best avoided. One company says you can not tell as soon as 7-8 weeks of pregnancy that the baby's sex to be born. This is possible because some have the baby's blood mixed with the blood of mother. A sample of blood from the mother house. If the laboratory is a Y chromosome in the whole sample, the baby is a boy because only males have a Y chromosome Failure Y chromosome is found, the baby is a girl. All that area of DNA testing has not been demonstrated, and there are demands for the current time against companies that reported sex fetal incorrectly. There are also ethical problems, even if this test is perfect.
Another category of DNA testing exists, genetic testing markers for certain medical conditions. Usually, if such proof is needed, your doctor may order and will take place in a laboratory that is authorized to give accurate results. More importantly, your doctor may advise that the means test. If you have a particular gene, which has a higher risk of developing certain diseases. This does not mean the disease, and a negative test does not mean that it will not.
You can do these tests at home. But there will be someone to explain what the results really mean. However, people do these tests, sometimes in private life or to prevent insurance companies health know the results and perhaps increase their rates. But the test conditions of law and, in fact, understand what the average results, you should consult your doctor or in some cases, a geneticist.
Starting today, DNA testing at home is best used to determine paternity or other family member when there is no legal requirement, or to obtain information about their ancestry.
