GRAMS STAINING
What does GRAMS STAINING measure?
Gram staining is a laboratory test that uses a special dye to examine microorganisms under a microscope. It helps classify bacteria as Gram-positive or Gram-negative based on their cell wall characteristics and may also show the presence of certain other organisms or inflammatory cells. Healthcare professionals may order it when an infection is suspected, as it can provide early information to support further testing and clinical assessment.
