Interpretation guide

Understanding results

A laboratory result is interpreted alongside personal history, family history, and other clinical information. Your healthcare professional is the right person to explain what your report means.

Pathogenic / likely pathogenicA clinically significant finding may support further evaluation with a qualified healthcare professional.
Benign / likely benignA finding classified as benign is generally not considered to explain a clinical concern on its own.
Variant of uncertain significanceA VUS is not used on its own to confirm or rule out a diagnosis; interpretation may change as evidence develops.

Before your sample

No fasting required unless your kit insert says otherwise. Bring a photo ID and, when applicable, the clinician order and insurance card.

Important limitations

No genetic test detects every possible cause of a condition. A negative, positive, or uncertain result may have different implications depending on the clinical context and test scope.
