[|Human|] i took a medical exam which included a chest xray and i noticed a small blur on the screen. The technician said if its something the doctor will let you know. Well now i have to redo the medical test for three consecutive days. Can you help ease my worries and tell me a reason why i would have to go for three consecutive days?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Fussy spot on chest x-ray is commonly seen with 1. Lung infection like tuberculosis or pneumonia 2. Old fibrotic lesions 3. Lung cyst 4. Malignant nodule. To rule out tuberculosis and other lung infection, sputum sample is needed. And specifically for tuberculosis, sputum should be given for consecutive three days. This is standard protocol for the diagnosis of tuberculosis. So get done three sputum sample reports. Also consult pulmonologist for further evaluation of this spot. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
