Guidance counselors for your genes?

At-home DNA tests, and disease-specific tests, make genetic counselors more important than ever

Genetic counselors can help anyone understand their genetic risks, or results of genetic tests.

Genetic counselors can help anyone understand their genetic risks, or results of genetic tests.

Once upon a time, getting your DNA tested was a rare thing – as rare as the genetic diseases that the tests tried to detect.

But no more.

These days:

  • You can order a kit through the mail that can tell you what diseases you’re at risk of developing down the road.
  • Your doctor can order dozens of tests to look for specific changes or variations in your DNA that might be causing your symptoms, or putting you at risk of future problems.
  • Or if you’re pregnant, you can have your doctor draw a vial of your blood, which you can send in to get information about the DNA of your future child.

And the ability to personalize treatment based on the exact gene variations you carry in your body is speeding up for many conditions.

How is an ordinary person supposed to make sense of all this genetic information?

And what do you do if you take a test and it shows you have a high risk or a current problem?

Fetal DNA Testing

Fetal DNA TestingIn late 2011, a new method of fetal genetic testing was introduced. Called cell-free fetal DNA testing or non-invasive prenatal testing (NIPT), this testing uses maternal blood to test for abnormalities in the fetal DNA. First introduced to detect Down syndrome (trisomy 21), the test is now also used to detect the less common trisomies 18 and 13 as well as other conditions.  This type of test is offered by several different companies that each have their own brand name for the test.

We offer NIPT to all women at increased risks for the designated conditions.  Those in the high-risk group include women over the age of 35, someone with a blood test result or ultrasound marker associated with a chromosome abnormality, and anyone with a family history or previous pregnancy with a history of one of these conditions.
