Description
Why It’s Done:
This test is crucial because different Mycobacteria species cause different types of infections and respond to different treatments.
It is done to:
• Differentiate between TB and non-tuberculous mycobacterial infections
• Guide appropriate antibiotic therapy, as drug susceptibility varies between species
• Identify atypical mycobacteria in patients with persistent respiratory or systemic symptoms
• Support diagnosis in immune-compromised patients where NTM infections are more common
• Assist in public health surveillance and outbreak control
Preparation:
• No special preparation is typically required.
• Sample type depends on the site of infection (e.g., sputum, lymph node aspirate, bronchoalveolar lavage, or biopsy).
• The sample should be collected using sterile technique and transported properly to avoid contamination.
• Follow your doctor or lab’s instructions for sample collection, especially for respiratory or invasive samples.
