How bronchitis is diagnosed: exam first, when chest X-ray, sputum TB test and spirometry are actually needed.
Bronchitis is mostly a listening-and-examining diagnosis - no single test names it. The doctor's real task is ruling out the illnesses that mimic it, especially pneumonia.
Most healthy adults with classic acute bronchitis need NO tests. Testing is for red flags and uncertain cases:
Duration, mucus changes, fever highs, breathlessness, smoking and cooking-fuel exposure, past lung disease, and everything you have already taken - including kadhas and over-the-counter syrups. It shapes both safety and the plan.
Classical diagnosis of Kasa rested on close listening too - the sound of the cough, the sputum's color and quantity, the patient's strength, the season and habits. Their five-type classification was the era's differential diagnosis. The modern version adds the chest X-ray and spirometer; the careful history comes first in both.
Bronchitis is diagnosed by story and stethoscope; X-ray rules out pneumonia when red flags appear, a sputum test rules out TB past 2 weeks, and spirometry answers the chronic-cough question.
