What color is normal for wound drainage?
Normal wounds have normal drainage—it’s clear or there is a little bit of blood or yellow color. The amount of drainage, and the amount of blood in it, should lessen as the wound heals. Abnormal wounds look angry and have angry drainage. They get worse—more tender, more drainage, more bleeding, more swelling.
Why would a wound turn green?
Gangrene is a dangerous and potentially fatal condition that happens when the blood flow to a large area of tissue is cut off. This causes the tissue to break down and die. Gangrene often turns the affected skin a greenish-black color.
What does green pus mean?
Pus can sometimes be green because some white blood cells produce a green antibacterial protein called myeloperoxidase. A bacterium called Pseudomonas aeruginosa (P. aeruginosa) produces a green pigment called pyocyanin. Pus from infections caused by P. aeruginosa is particularly foul-smelling.
How do you tell if a wound is healing or infected?
Here are some symptoms to monitor if you suspect your wound is infected:
Warmth. Often, right at the beginning of the healing process, your wound feels warm. Redness. The area may be swollen, sore, and red in color right after you’ve sustained your injury. Discharge. Pain. Fever. Scabs. Swelling. Tissue Growth.
What Colour is an infected wound?

What color is serous drainage from a wound?
Serous drainage
It is often thin and watery and will usually have a clear to yellowish or brownish appearance. Small amounts of serous drainage are normal during the first stages of healing. Continuous serous drainage may be a sign that there are high levels of bacteria living on the surface of the wound.
What are the stages of wound healing?
The cascade of healing is divided into these four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation.
Why is my scab greenish yellow?
If you have a scab, it’s considered normal to see it change into a yellowish color over time. This is completely normal and is the result of the hemoglobin from red blood cells in the scab being broken down and washed away.
