What Is This Test For?
Guided drainage procedures, such as those performed for abscesses or fluid collections, may require analyzing the fluid removed. This test checks whether the fluid contains proteins, which can indicate inflammation, infection, or other underlying conditions. Protein presence in unexpected sites may signal abnormal fluid buildup or infection.
How Is the Sample Collected?
A healthcare provider will collect the fluid using a guided drainage procedure, such as a needle or catheter. The fluid is then sent to the lab for analysis. You may feel some discomfort during the procedure, but it is typically brief and managed with local anesthesia if needed.
What Does the Result Mean?
The result is qualitative, meaning it indicates whether protein is present (positive) or not (negative) rather than providing a specific quantity. High protein levels in the fluid may suggest conditions like infection, inflammation, or malignancy. Low or absent protein could indicate normal drainage or other specific clinical scenarios.
Common Conditions Monitored
This test is often used to monitor drainage from abscesses, cysts, or other fluid collections. It helps doctors determine if the fluid needs further treatment, if infection is present, or if the drainage site is healing properly.
