Microscopic colitis is a type of inflammation of the colon that causes non-bloody watery diarrhea and most often impacts middle-aged females. The condition can be distinguished into two types, lymphocytic and collagenous. The difference between the two types are minor; both are characterized by an increase in lymphocytes with collagenous colitis also having a thickened subepithelial collagen layer.
This APP is addressing lymphocytic colitis.
By quantifying the T-lymphocytes targeted by the CD3 marker in different tissue compartments, a diagnosis can be determined.
