How to confirm tb?
Patient: Before 4 monthes i got typhiod and after that i have gaind 3 kg .Recently i went to doc for my delayed periods who told me for tb test myreports shows tb IgA is negative,tb IgG is 160.00 and tb IgM is 1.49. Am i effected by tb and only blood test enough to onfirm tb? Doctor: Thanks for asking in healthcaremagic forum  Usually Tuberculosis is diagnosed by sputum smear and X-ray tests not antibody tests. I think you have confused typhoid with tuberculosis. Typhois also diagnosed with widal test. So, please send me the details regarding the test report for further suggestions. All the best.
