Urine - Gram Stain

Urine Gram Stain is a rapid diagnostic test that involves staining a urine sample to identify the presence and type of bacteria under a microscope. It helps differentiate bacteria into Gram-positive and Gram-negative organisms based on their cell wall characteristics.

The urine sample is treated with a special staining technique called Gram staining. Under a microscope, bacteria appear in different colours:

• Gram-positive bacteria: Purple/blue
• Gram-negative bacteria: Pink/red

This classification helps doctors choose appropriate antibiotics.

The purpose of this test is to:

• Detect bacteria present in urine
• Classify bacteria as Gram-positive or Gram-negative
• Aid in early diagnosis of urinary tract infections
• Assist in selecting appropriate antibiotic treatment
• Provide preliminary results before culture testing
