Worried about your health future? An American commercial company offers a "genetic assessment" based on DNA samples. The "Washington Post" newspaper publishes that dozens of boxes are sent to the company every day and are stored in neat rows near the laboratory. It contains samples of blood and mucus, which the senders hope will serve as an opening for a glimpse into their medical future. Over the next few weeks, technician Desna Vincent from Genelex and her colleagues will perform a "genetic evaluation" of these samples and analyze the DNA, to check what the health status of the subjects will be in the future.
For example, problems in the genes that affect the body's handling of fats may increase the risk of heart disease; Problems in the genes that help get rid of toxins may affect the chance of getting cancer due to smoking; And genes related to vitamin D metabolism may affect bone formation. Based on the findings, the company provides recommendations for diet, lifestyle and medications that may help the person. The bill - depending on the number of tests sent - starts at $400.
Companies like Genlex are pushing medical science into territory that once belonged to horoscopes and fortune tellers. They predict a person's health in 10-20 years or more. Other companies announced that they could predict the chances of diabetes, liver disease, blood clots and even alcoholism and gambling.
Today there are genetic tests for about 1,100 diseases: twice the number of tests that existed five years ago. The popularity of the tests stimulates the new "DNA diet", whose recommendations are based on genetic analysis, and the sales of books promoting this diet.
Scientists claim that the tests are the fulfillment of the promise since the completion of the mapping of the human genome was announced: "The adoption of genetic tests has the potential to turn the healthcare system upside down. This will be the end of 'one-drug-fits-all,'" said Howard Coleman, founder of Genelex.
But other scientists are concerned that the commercialization of genetic tests is premature. They say that while some tests have proven efficacy, others are based on less universally accepted research. According to them, the connection between genes, lifestyle and environmental factors is weak.
