Histopathology and Cytology . A number of slides will usually be prepared from different levels throughout the block.
from a surgical procedure then a pathologist looks at the tissue sample and selects the part most likely to yield a useful and accurate diagnosis - this part is removed for examination in a process commonly known as grossing or cut up. 11 Test Referral.

Please click here to read our user guide. Three main types of specimen are received by the pathology laboratory.Specimens received by the pathology laboratory require tissue preparation then are treated and analysed using techniques appropriate to the type of tissue and the investigation required. Complete a Histopathology test requisition and send with specimen(s). In fact, if you’re sick, many decisions about your care will come down to the results of your blood and pathology tests.
For immediate diagnosis during a surgical procedure a frozen section is performedLarger specimens include whole organs or parts thereof, which are removed during surgical operations.
It is the microscopic examination of biological tissues to observe the appearance of diseased cells and tissues in very fine detail.

Only one Histopathology test requisition is needed per patient; Each container and specimen must be separately identified on the test requisition ; The test requisition should contain patient's date of birth, sex, clinical information and anatomic source of tissue
Volume 76, Issue 1 Special Issue: Annual review issue: Gynaecological Pathology: WHO 2020 and Beyond Histopathological examination of tissues starts with If a large sample is provided e.g. The final report will be concluded after incorporation of all essential Histopathology (or histology) involves the examination of sampled whole tissues under the microscope. To see the tissue under a microscope, the sections are stained with one or more The most commonly used stain in histology is a combination of The histological slides are examined under a microscope by a The microscopic examination of tissue in order to study and diagnose disease This type of material is usually liquid rather than solid, and is submitted for cytology rather than histology (see Specimens received by the pathology laboratory require initial tissue preparation, then are treated and analysed using techniques appropriate to the type of tissue and the investigation required.For immediate diagnosis during a surgical procedure, which may influence the type of surgery being performed, a frozen section is done. After this the thin section mounted slide is stained and a protective cover slip is mounted on it. But, with the advent of Water is removed from the sample in successive stages by the use of increasing concentrations of Once the wax embedded block is finished, sections will be cut from it and usually placed to float on a waterbath surface which spreads the section out.
Certain specimens (especially biopsies) can undergo In addition to formalin, other chemical fixatives have been used. In contrast, cytopathology examines free cells or tissue micro-fragments. Histopathology refers to the microscopic examination of tissue in order to study the manifestations of disease. Histopathology (or histology) involves the examination of sampled whole tissues under the microscope. This is performed using a thinner needle than that used in a core biopsy, but with a similar technique.
Larger samples are cut to correctly situate their anatomical structures in the cassette. Please note this list may not show our full repertoire of tests. Histopathology can be defined as the microscopic examination of a biopsy or surgical specimen to study the manifestations of disease.
Histopathology. Examples include a uterus after a hysterectomy, the large bowel after a colectomy or tonsils after a tonsillectomy.Pieces of tissue rather than whole organs are removed as Fluid and very small pieces of tissue (individual cells rather than groups of cells, e.g. within fluid from around the lung) can be obtained via a fine needle aspiration (FNA). Blood and pathology tests leave many people squeamish, but they’re an important part of detecting, diagnosing and treating disease.
