When most people hear the term 'DNA blood test', they think of such things as using the test to convict or acquit criminals, or to determine the paternity of a child. The fact is, however, that the DNA blood test is a tool that can help people in a lot of different situations. For people who suffer from such conditions as hemophilia, sickle cell anemia, and leukemia ñ conditions that require a large number of blood transfusions - blood tests for DNA can be life saving.
A DNA blood test can determine compatibility between a blood donor and a blood recipient far beyond simply matching their blood types. It can determine deeper levels of compatibility that can help to avoid the side effects that can often occur with blood transfusions, especially when they are required on a regular basis. The test can detect subtle variations in blood types and match donors to recipients more closely.
When there is something as helpful as a DNA blood test, there can be drawbacks that need to be addressed. The facts about individuals that this type of test can reveal can conceivably be used by health insurance companies to determine which people are too risky to insure and which are not. This type of DNA profiling is, at this time, illegal, and it is up to lawmakers and their constituents to see that it stays that way. With technological progress there is always risk of misuse, and it can only be by constant vigilance that the DNA blood test always be seen as something that is used to help people, and not to hurt them.
