Understanding Your Results

Results post to your secure online account usually in 2–3 business days as positive, negative, or indeterminate. A positive result means you've been exposed to TB but doesn't distinguish latent from active infection. It should be followed up with a clinician, who may order a chest X-ray or additional evaluation.
