Test Name: Trichrome Masson’s


Methodology: Special Stains


Test Description

Masson’s Trichrome Stain Kit is used to identify muscle, collagen fibers, fibrin and erythrocytes in tissue sections on the Artisan™ Link and Artisan™ Link Pro Staining Systems. Masson’s Trichrome is often used to demonstrate increased collagen deposition that is associated with replacement of functional tissue by scar tissue. This is useful in the assessment of sclerosis of the liver in which thickened collagen replaces normal tissue causing liver dysfunction. Muscle: red, collagen: blue, fibrin: pink, erythrocytes: red and nuclei: blue/black.
