Tubercolosis, PCR

Preparation:
No special preparation is usually required.
Inform your healthcare provider of any antibiotics or TB medications you're currently taking, as these may affect test accuracy.
The sample type (sputum, blood, urine, or tissue) depends on symptoms and the suspected site of infection.

Fasting Needed:
Not required, unless specified by your doctor for accompanying tests.

Best Time for Test:
Morning sputum samples are preferred if the test is for pulmonary TB, as they typically yield better results.
