PPD positive is not significant of diagnosis of TB. positive PPD only indicates that she has or has had TB.Since her 3-day sputum smear is negative, it is better for her to do a sputum culture( the problem is that this test takes no less than 3 weeks to get the result). A positive culture for M. tuberculosis confirms a diagnosis of TB. Wish her good luck!!
sorry to hear that!
