What is stain precipitate?

Stain precipitate mimics bacteria including cocci and Mycoplasma. The stain precipitate is usually purple, while bacteria are blue (with Wright's stain).



The same goes for platelets. Why do they turn purple?

There are serotonin, which reduces the size of lesioned vessels, slows down the hematic flux and fibrin, which traps cells and forms the Clotting. Even though platelets appear roundish, they are not cells. They are a deep purple color in the Giemsa stained smears.

The same goes for blood smear. After fixing, the slide will be stained to distinguish the cells. These stains can be used to detect white cells, red cells, and other abnormalities in platelets. Other specialized stains are often used by hemopathologists to aid in the diagnosis of blood disorders.

This being said, how often should you change the Diff Quik stain?

Good laboratory practice should include documentation of changing each Diff­Quik stain at regular intervals (e.g. every week if there are an average of five weekly evaluations).

What are the factors that influence a good PBF score?

To achieve a perfect blood smear, three factors can be modified: speed, angle, and drop size. 1. The film will be thinner and longer if it is moved faster than the spreader slide. The slide will be shorter and thicker if it is moved slowly.
