What is cytospin test?
A cytocentrifuge, sometimes referred to as a cytospin, is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined.
What is CSF cytospin?
Description: Cytocentrifugation is a method of gentle and controlled centrifugation, that produces a monolayer of preserved, displayed cells (when present). These are flattened constructively on a slide, offering a more open nucleus and more visually interpretable nuclear material.
What is the principle of the Cytocentrifuge?
The principle of all cytocentrifugation techniques is that the cell is denser than the suspending fluid and under an applied force the cell will have greater momentum than the fluid. The cellular movement occurs after passing through the sample chamber.
What cytology is used for?
Cytology is the exam of a single cell type, as often found in fluid specimens. It’s mainly used to diagnose or screen for cancer. It’s also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas.
What is the difference between centrifuge and cytocentrifuge?
As verbs the difference between centrifuge and cytocentrifuge. is that centrifuge is to rotate something in a centrifuge in order to separate its constituents while cytocentrifuge is to separate cellular material in such a device.
What stain is used to stain a cytospin slide?
Allow the slides to dry in air for several minutes and then stain tham with Wright-Giemsa stain. Cytospin slides may be placed in an automatic stainer, such as Hema-Tek, or stained manually.
How do you store a cytospin slide?
The cytospin slides for IHC can be stored theoretically for indefinite time for IHC. The most important factor is FIXATION AND PREVENTING smears from getting dry. For storage longer than an year , they can be fixed with methanol and kept at 4-8 degrees for as long as 2 to 3 years.
Can you fix cells overnight?
Fixation was optimized by incubation at 4°C overnight. Under this condition, cells can be preserved for a long time. Before staining, remove ethanol by wash with cold-PBS three times.
What is cytology vs histology?
Cytology is the study of individual cells of the body, as opposed to histology which is the study of whole human tissue itself.
Is cytology a biopsy?
Fine needle aspiration (FNA) is sometimes considered a cytology test and is sometimes considered a biopsy. It’s discussed in Types of biopsies used to look for cancer.
What is the cytospin process?
The cytospin process is a simple procedure. Cells are washed in a serum and/or albumin based PBS or culture media solution. The cells are resuspended in up to 500 µl of this solution. A cytofunnel is attached to a glass slide and slide carrier. The entire apparatus is inserted into a cytocentrifuge and the cell suspension is added.
How do you prepare cytospin slides?
Cytospin preparations A cytospin is obtained by employing centrifugal force to isolate, concentrate and deposit a monolayer of cells from a dilute cell suspension onto a circular area on a slide. The objective is to keep cells intact enabling the morphology of the cells to be examined.
How to optimize the loading volume of the cytospin?
The loading volume should be optimized for each cell line used. Close the Cytospin lid and centrifuge at 1000 × g for 5 min. Remove the slides, filter cards, and cytofunnels from the centrifuge. Be careful not to move the filter paper on the slide and so damage/smudge the cell preparation.
How is cytospin used to diagnose cancer?
Techniques in Cytology – Cytospin: Distinguishing Benign Cells from Malignant Cells. It assesses single cells and clusters of cells from sources such as malignant effusions and peripheral blood. Effusions are fluids that leak from blood and lymph vessels and aggregate in tissues and cavities within the body.
