Fibrinous exudates are thick and sticky and have a high cell and fibrin content from EXPH 460 at WVU
Serous drainage is clear and may be slightly yellow or colorless in appearance. It is thin and watery and may make a bandage wet without leaving a stain of color. Serous exudate, or discharge, is normal from a wound in the early stages of healing, typically in the first 48-72 hours after the incision is made. While serous fluid is normal in small amounts, large amounts of this clear fluid leaving the incision line should be reported to the surgeon.
