About this test

The Sputum Gram’s test identifies bacteria in sputum samples to help diagnose respiratory infections and guide treatment.

The Sputum Gram’s test is a laboratory test used to detect and classify bacteria present in a sputum sample (mucus from the respiratory tract). The sample is stained using the Gram staining technique and examined under a microscope.

This test helps differentiate bacteria into Gram-positive and Gram-negative types, providing quick preliminary information about the cause of respiratory infections such as pneumonia, bronchitis, or lung abscess.

It is often used as an initial diagnostic tool and may be followed by culture and sensitivity testing for precise identification and antibiotic selection.

Test Recommended For

  • Individuals with persistent cough
  • Patients with suspected respiratory infections
  • People with symptoms like fever, chest pain, or breathlessness
  • Individuals with pneumonia or bronchitis
  • Patients advised for sputum analysis
