Why you should have Genetic Testing

Why you should have Genetic Testing

The results tell of genetic markers that, if present, may signal susceptibilities to certain health conditions. These markers, called SNPs (or single nucleotide polymorphisms), are variations in gene sequences. SNPs don't cause disease, but can help determine the chances of developing a certain illness, according to the U.S. Department of Energy's Genome Program.

Results indicating you're at above-average risk for contracting a disease don't guarantee you'll get it, just as results showing no risk markers don't mean you won't. But for some, acting on the information like deciding to quit smoking or make diet changes may help prevent the disease's development or lessen its effects, according to Navigenics, a genetics testing company.

What Genetic Testing Does

From the date that a sample is taken, it may take a few weeks to several months to receive the test results. Results for prenatal testing are usually available more quickly because time is an important consideration in making decisions about a pregnancy. The doctor or genetic counselor who orders a particular test can provide specific information about the cost and time frame associated with that test. The tests can tell a mother if she has a baby with a disease and she can tell the gender and the weight and age of the baby. This can also tell her if her baby has a increased risk of getting diseases

Cost of Genetic Testing

Ten years ago, you could take a test to find genetic links for about 900 diseases—today, that number is more than 2,500. And what was once considered an expensive procedure that could only be administered in a medical setting can now cost as little as $100 for a DNA test you can take at home. The cost increases if more than one test is necessary or if multiple family members must be tested to obtain a meaningful result. For newborn screening, costs vary by state. Some states cover part of the total cost, but most charge a fee of $15 to $60 per infant.

Genetic testing is a great thing to do because you can check to see if your baby has a disease so you can work out treatments for them.
