A New Era in Medicine

Genetic tests developed by Myriad Genetic Laboratories also reveal information that predict a person’s response to certain medications. Predictive information revealed by the test enables doctors to customize and target treatment in advance to minimize the chance of side effects.

TheraGuide^® 5-FU is the first test from Myriad in the field of personalized medicine. It is a simple blood test to look for genetic variations that help predict your risk for side effects from the chemotherapy drug called fluorouracil (5-FU), the backbone of therapy for colorectal cancer and many other cancers. By testing for certain genetic variations before treatment, TheraGuide 5-FU can help predict how your body is likely to react to this medication.
