Would You Use an Over-the-Counter Genetic Test?

Starting Friday, Walgreens shoppers can buy an over-the-counter genetics test from Pathway Genomics at 7,500 stores across the country. Priced at $20 to $30, the kit claims to offer information on users' possibility of developing conditions like Alzheimer's disease, breast cancer, or diabetes. Access to the scientific analysis online, however, costs another $79 to $179. Researchers are cautioning consumers, saying that without a full evaluation of other factors, like lifestyle and environment, genetic testing is incomplete when diagnosing a potential illness.
