(based on 123 customer ratings)

Author: Tanisha N. Neely, HT(ASCP)
Reviewers: Diana Harrington, BS, HT(ASCP); Carla Shoffeitt, MSM, HT(ASCP)

This course is the second in a series of courses that will explore special stains used in the clinical histology laboratory. Basic connective tissue staining mechanisms and classifying connective tissue elements will be discussed. The material presented details the chemistry, diagnostic application, and staining protocols for special stains used to demonstrate connective tissue in samples.

Continuing Education Credits
