The Importance of Clinically Correlating Tuberculosis With Indeterminate QuantiFERON Gold Test

Tuberculosis (TB) is a highly contagious airborne infection of the lungs. It can present in active form, as well as latent form. The clinical manifestations of tuberculosis can present as either subacute or chronic. Some symptoms include weight loss, night sweats, fevers, and hemoptysis. This case highlights the importance of clinical judgment and follow-up testing when patient presentation does not correlate with initial results. We share a perplexing encounter where a 34-year-old male presented with hemoptysis, fevers of unclear origin, and an indeterminate QuantiFERON Gold result and was empirically started on rifampin, isoniazid, pyrazinamide, and ethambutol (RIPE) therapy. RIPE therapy includes the gold standard medications used to treat tuberculosis.
