Quest Diagnostics Ireland

We know that waiting for a test result can be a very anxious time for any patient. We work to make sure that results are delivered on time, so that general practitioners have the insights they need to provide quality care. We also provide a toll-free number where they can consult with our medical experts about a patient's test results.
