Thanks for coming to HCM
MDR can happen for the first time if the person has contracted TB from an MDR patient.
I don;t know how your doctor came to know that it is active tb
, if sputum is negative...was it the decision based on chest xray....
MDR can be diagnosed only on culture and sensitivity report of sputum in which there is growth of mycobacterium tuberculosis
and is resistant to Isoniazide and rifampicin
....the second way to diagnose is via line probe assays which are to be done on sputum posistve samples and the report comes in 2 days
Question comes If it is proven MDR then why cat 1 is being continued why not to start cat 4.
Ask your Doctor how they have diagnosed MDR and get yourself clear of your doubts...or else post your reports here...
