Sputum Culture, Bacterial

A sputum culture test is a laboratory analysis used to detect and identify bacteria or fungi that may be causing a respiratory tract infection. The test involves collecting a sample of sputum (mucus coughed up from the respiratory tract) and cultivating it in a lab to see what types of microorganisms grow. This helps in diagnosing infections like pneumonia, bronchitis, or tuberculosis. The results guide healthcare providers in choosing the most effective treatment, particularly in selecting the right antibiotics if a bacterial infection is identified. The test is essential for accurate diagnosis and effective treatment of respiratory infections.
