Discussion . give some evidence. Do you know anyone who had a biopsy done before, what was their experience like? This is the first step taken before sectioning, tissue fixing and staining. Can you explain the importance of this procedure, why is it done and what is the lab tech looking for?
Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.

- A biopsy is a procedure done for the cytological and histological examination of the internal body parts. For eg: liver, kidney, bone marrow, etc. One of the relatives had undergone this procedure (liver biopsy) to detect any abnormality in the hepatocytes. She was really worried before the procedure and mainly about the biopsy needle. When she entered the biopsy room she was so much worried but the nurse over there made her feel comfortable and explained the procedure. My aunt was so much relieved then. After the biopsy, she was given the right lateral position to prevent bleeding and truly she was feeling comfortable in that position and her stress of the procedure to be undergone had released.
