It is made up of the chemical DNA. Like any other human conducted analysis, genetic tests too are prone to errors arising from several possible sources. This therefore puts to question the high levels of trust that has been bestowed findings obtained in this field of science. The HGPI (2010) clearly states the limitations accompanying genetic tests.
The tests give only a probability for developing the disorder. One of the most serious limitations of these susceptibility tests is the difficulty in interpreting a positive result because some people who carry a disease-associated mutation never develop the disease. Scientists believe that these mutations may work together with other, unknown mutations or with environmental factors to cause disease (HGPI 2010).
The authors further open another front meant to make the individuals that the tests are also prone to laboratory errors. Sample misidentification, contamination of the chemicals used for testing, and other unlisted factors are attributed to the experimental errors associated with genetic testing in the laboratories (HGPI 2010).
Furthermore, several complexities accompany interpretation of the analysis results, further compounding the problem. Some medics feel that with time the field will have grown in diversity to such sophistication that it will be able to offer competing options for unique kind of tests and solutions to susceptibility to many diseases. Until these issues are resolved or technology soars to such heights, it will be impossible to certainly determine the effective efficiency of the tests.
Fetal genetic testing is credited for being carried out under some of the most convincing environments in terms of sterility. For this reason, it is touted as being among the most reliable tests under genetic testing. However, it is estimated that a sure treatment of genetic conditions identified with the parents could offer a better solution to fetal genetic testing.
