The normal range for tuberculosis (TB) interferon-gamma release assays (IGRAs), such as QuantiFERON-TB Gold tests, typically indicates a negative result when the interferon-gamma level is below 0.35 IU/mL. A positive result is usually indicated by levels above this threshold, although specific cutoff values may vary by laboratory. Always consult with a healthcare provider for interpretation in the context of clinical symptoms and other diagnostic results.
