I'm really worried about my friend. Theyve had this cough for about a month now, but no fever. We got some test results back, and one of them says "sputum AFB stain positive" with "acid-fast bacilli seen," while the other test indicates "no pathogenic organisms were isolated after 18-24 hours of incubation." I'm confused about whether my friend actually has TB or not. Could you help me understand what these results mean?
Pulmonologist opinion is advised to the patient.
