Can x-ray alone enough to diagnose PTB?

My father was diagnosed with PTB last month. He didn't and doesn't have any signs and symptoms other than shortness of breath. I'm just curious if the two chest x-rays PA would already be enough to diagnose PTB? I've read that chest x-ray is not a definitive diagnostic tool.. There should be other diagnostic tools like AFB, skin test, etc. Is that right? The doctor based his diagnosis because of the progression of the disease from x-ray 1 to x-ray 2. Can someone please enlighten me on how doctors diagnose TB?

Hi, and thanks for your query on eHealth forum!

You are right, the diagnosis of pulmonary TB is based on Chest-Xray, Montoux test, demonstration of AFB in sputum, other blood tests like SPOT test, whole blood interferon-γ test or other TB antigen based tests.

Please consult your healthcare provider for further guidance.
