Gram Stain.

Overview:
A Gram stain is a laboratory procedure used to classify bacteria based on the characteristics of their cell walls. The test uses a special dye that differentiates bacterial species into two categories: Gram-positive and Gram-negative. This classification is helpful in identifying bacteria and determining the appropriate treatment, as different types of bacteria respond to antibiotics differently.

What it detects:
The Gram stain detects the presence of bacteria and classifies them based on their cell wall structure. It can help identify bacterial infections and guide doctors in choosing the right antibiotics. Gram-positive bacteria will appear purple, while Gram-negative bacteria will appear pink under a microscope.

Who should get it:
The Gram stain is commonly used when a bacterial infection is suspected, especially if the source of infection is unknown. It can be performed on samples from wounds, blood, urine, sputum, or other bodily fluids to help identify the type of bacteria causing the infection.

Sample required:
A sample of bodily fluid or tissue (such as blood, urine, sputum, or wound swab) is required for this test.

Fasting requirements:
Fasting is not required for this test.

Processing time:
