What is Group A Streptococcus (GAS) bacteria?
The minimum amount of sterile normal saline or sterile water required for wound cleansing before sampling.
What is 100 mL?
This wound swab technique is preferred because it provides a more representative sample and reduces contamination.
What is Levine's technique?
Approx. this percentage of non-healing wounds contain biofilms.
What is 80%?
Name one medical condition that increases the risk of developing iGAS.
What is diabetes? (Also accepts HIV infection, cancer, heart disease, lung disease & alcohol use disorder)
If a second wound requires sampling, this additional item must be collected.
What is a second sterile swab kit?
Before collecting a wound culture, the wound should first be cleansed with this solution.

What is delayed wound healing?
Respiratory droplets, contact with mucous membranes, exposure of non-intact skin to infectious secretions, wound drainage, and contaminated needles are all examples of these.
What are the modes of iGAS transmission?
The number of glove sets required for wound sampling and applying a new dressing.
What are two sets of gloves?
This technique requires selecting a 1 cm² area of viable tissue and rotating the swab while applying pressure to express fluid from the wound tissue.
