Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Patients prescribed 5-Fluorouracil (5-FU) chemotherapy.
  • ✓Individuals with a history of severe adverse reactions to 5-FU.
  • ✓Patients experiencing unexpected treatment response or toxicity with 5-FU.
  • ✓Family history of adverse reactions to 5-FU.
  • ✓Assessing risk before initiating 5-FU therapy.

In plain language

What this test helps you understand

This test helps clinicians personalize 5-Fluorouracil chemotherapy by identifying genetic variants in the DPYD gene that may affect drug metabolism, potentially leading to reduced toxicity and improved therapeutic outcomes.
The 5-Fluorouracil (5-FU) Toxicity and Chemotherapeutic Response DPYD Variants test is a genetic analysis used to understand how your body processes the chemotherapy drug 5-Fluorouracil. This information is crucial for personalizing cancer treatment.

This test looks for specific variations in the DPYD gene. This gene provides instructions for making an enzyme that breaks down 5-FU. Certain genetic variants can affect how quickly or slowly this enzyme works, influencing how your body responds to the drug.

Understanding your DPYD gene variants allows your doctor to make more informed decisions about your 5-FU chemotherapy dosage. This can help maximize the drug's effectiveness against cancer while minimizing the risk of severe side effects or toxicity.
