A Gram stain of a Pus Swab helps to identify the type of bacteria causing an infection. This information helps the doctor in deciding the most appropriate antibiotic for treatment.
When this test is required
The test is typically ordered when a patient shows symptoms of an infection such as a fever, redness, swelling, and pus formation.
What the Test Detects
The test involves staining the collected pus sample with crystal violet stain, iodine solution, alcohol, and safranin solution. The stain differentiates the bacteria into two broad categories – Gram-positive and Gram-negative.
Preparation for the Test
There is no specific preparation required for the test.
Sample Requirements
A Pus Swab is used for the test. The swab is gently rubbed against the infected area to collect a sample.
Additional Notes
A Gram stain report provides preliminary information on the type of bacteria present in the sample, and further testing, such as culture and sensitivity, may be necessary for a definitive diagnosis and treatment plan.
