Appendicitis is an inflammation of the appendix. It usually causes sudden pain in the lower right abdomen, often accompanied by nausea, vomiting, and fever. Here are the most common tests and evaluations for diagnosing appendicitis:
Here you will learn about Cytology vs histology. Cytology is widely used in diagnostic medicine, especially in the identification of abnormal cells indicative of diseases such as cancer. Fine needle aspiration and pap smear are the most common techniques in cytology. On the other side, Histology unveils tissue intricacies, showcasing cell collaboration and specialized functions. … Read more
A microtome is a laboratory instrument used for cutting extremely thin sections of materials, typically biological specimens, for microscopic examination. It is an essential tool in various scientific fields, including biology, and histopathology. These instruments are essential for studying the intricate structures of tissues, cells, and various specimens, contributing significantly to our understanding of various … Read more
Gout is a type of arthritis that affects millions of people worldwide. It is characterized by sudden and severe pain, redness, and swelling in the joints, particularly in the big toe. This painful condition is caused by the buildup of uric acid crystals in the joints, which can result in an inflammatory response. Gout attacks … Read more
10% Neutral Buffered Formalin is widely used in labs for preserving biological tissues. It stabilizes tissue structures by cross-linking proteins, and the buffer system ensures a neutral pH, which helps reduce tissue damage during fixation. Here’s the composition of 1 liter of 10% Neutral Buffered Formalin: How to prepare 1 liter 10% neutral buffered formalin … Read more
It is fixation is important in tissue processing because it preserves the anatomy of different tissues. It makes tissue hard so that a thin section can be made from it. Tissue fixation means the process by which components of the cell and tissues are fixed physically and partially by chemical methods. So that it … Read more
There are many types of specimens for cytological examination. Cytology specimen collection and handling are very sensitive. Each sample has its own standard operating procedure.

We collect and deal with different types of tissues biopsy in the histopathology laboratory. The tissue collection method in the histology laboratory has the following steps. Role of Fixative in tissue collection method After the removal of surgical specimens, they should be placed in a container filled with fixative. For the best fixation, tissue should … Read more
Tissue staining is the second step after collection.Different tissues are colored.differently.There are three main types of histology stains. Specially prepared dyes are used for such staining purposes. Such dyes are prepared by adding the cytochrome to a chromophore. Note: Cytochrome is a compound when mixed with chromophore, forms a dye. This dye can be acidic … Read more
Decalcification is a process used to remove calcium salts from tissue samples. This is primarily done in histology and pathology laboratories. It makes the samples suitable for further processing and microscopic examination. There are many methods, which used to check the decalcification of the different types of tissues. Here we will learn about “End point … Read more
