There are any number of genetic testing services on the world wide web. I am sure their numbers are growing as you read this post. Each of them offers their own array of tests and services which are packaged together in myriad forms. In situations where regulation is limited, it is up to the buyer to evaluate the products that are for sale. A few questions, in my opiinion, should be asked about these products before they are purchased.
First, what is the range of risk covered fby the genetic test? For example, does a test for breast cancer risk cover a 2 fold or a thirty fold range of risk? Based on the number if genes tested and their interactions, what range of risk is available for you to interpret your test score within for a reasonable appraisal of how likely you could be to get the disease? Second, does the price of the genetic test include a report that places the observed level of risk in the context of the population at risk? Ask yourself; if not then why not? Third, if a genetic counselor’s services are available.as part of a package that you are thinking about buying; the customer should verify the background and training of the genetic counselor as well as their availablity. In the United States, genetic counselors are accredited after a course of study that usually ends in a Master’s Degree. Find out about a genetic counselor’s credentials before you sign up.
