If sputum is +ve it is microbiologically positive

Yes, if sputum is positive for Mycobacterium tuberculosis, it is considered microbiologically positive for tuberculosis (TB). The presence of the bacterium in sputum is a definitive diagnostic sign of TB. A positive sputum test result indicates that the patient is infected with TB and requires treatment to prevent the spread of the disease to others.

It is important to note that a positive sputum test result does not necessarily mean that the patient has active TB disease. Further tests, such as chest X-rays and clinical evaluation, are required to determine if the patient has active TB disease and requires treatment.

In conclusion, a positive sputum test for Mycobacterium tuberculosis is considered a microbiologically positive result for TB and is an important diagnostic tool in the detection and management of the disease.
