Interesting Uses For DNA Testing

Accuracy Of A Diagnosis

Many medical conditions are associated with mutations affecting specific genes, so testing DNA can help with the accuracy of a diagnosis. Looking at genes can help doctors to determine if your symptoms are due to a specific condition. For example, if you have the signs of Huntington’s disease or cystic fibrosis, DNA testing can confirm this diagnosis, which is important because many conditions do not have any other definitive diagnostic methods. To test DNA, doctors may take a sample of blood, skin, saliva or hair, depending on the condition they are looking to diagnose. This is typically done in addition to other testing that will vary based on the condition the doctor suspects the patient has.
