  Cytology - LoveToKnow 1911
CYTOLOGY (from hums, a hollow vessel, and Xeyos, science), the scientific study of the " cells " or living units of protoplasm, of which plants and animals are composed.
All the higher, and the great majority of the lower, plants and animals are composed of a vast number of these vital units or " cells." In the case of many microscopic forms, however, the entire organism, plant or animal, consists throughout life of a single cell.
It is to the wealth of correlated observations and to the philosophic breadth of the conclusions in this paper that the subsequent rapid progress in cytology is undoubtedly to be attributed.

 Why perform a cytology smear in conjunction with a uterine culture?
The combination of endometrial cytology smear and culture results offer the most accurate diagnostic tool connected with uterine swabbing and pathogenicity (an endometrial biopsy is probably more accurate, but is not necessarily cost-effective in all cases).
It has been suggested by some that if no neutrophils are identified on a cytology smear, it is not necessary to perform a culture of the sample, and the mare may be considered "clean".
A cytology smear is prepared using a sample taken from the non-centrifuged portion of the recovered fluid.

 A detailed description of brush cytology, and the oral brush biopsy.
The mechanism of cytology, regardless of its application to cervical, bladder or oral mucosal lining, is based upon the fact that dysplastic and cancerous cells tend to have fewer and weaker connections to each other and to their neighboring normal cells in the surrounding tissue.
Although many authors initially concluded from their data that oral cytology could serve as a useful adjunct to biopsy, the current general perception among both dentists and physicians is that the sensitivity of oral cytology is not sufficient to warrant its widespread use as a screening modality to triage visible lesions.
Furthermore, since the sensitivity of cytology is often dependent on a tedious visual search for a potentially rare abnormality on the microscope slide, the precancerous or cancerous cells collected on the slide may not have been detected by the laboratory pathologist.

 ACS :: Testing Biopsy and Cytology Specimens for Cancer
A cytology specimen usually is easier to obtain, causes less discomfort to the patient, is less likely to result in serious complications, and is less expensive than a tissue biopsy.
A sample of cells from a biopsy, cytology specimen, or blood specimen is treated with special antibodies and passed in front of a laser beam.
For cytology specimens, the gross description is very short and usually indicates the number of slides or smears made by the doctor.

 VetRef: Canine Exfoliative Vaginal Cytology
Simply put, vaginal exfoliative cytology consists of the observation of types and quantities of "loose" vaginal cells under a microscope and arriving at a determination of a bitch's reproductive or physiological status at any given time.
Vaginal cytology is a highly useful, noninvasive, and inexpensive tool in both the assessment of canine reproduction status and as an aid to differential diagnosis.
For example, vaginal cytology cannot identify the day of ovulation or fertilization and the exact day for breeding cannot be determined from an evaluation of smears.

 Peritoneal cytology in staging of gastric cancer
Cytology is positive in 6,9% of cases without macroscopic peritoneal dissemination and in 42% of those with peritoneal dissemination.
When the tumor invasion is limited to the mucosal or submucosal layer, positive cytology is absent; however when the invasion includes the muscolaris propria, subserosal layer, serosal surface and adjacent structures, the rate of positive cytology is 5,9%, 9,8%, 27,3% and 21,4% respectively.
Administration of anticancer drug during surgery seems reasonable when the rapid results of cytology are positive, since the accuracy of rapid result of cytology has been proven from this study and positive cytology has been revealed as a sensitive predictor for the development of peritoneal recurrence.

 What is Cytology?
Cytology became, in the 19th century, a way to describe and identify cells, and also to diagnose certain medical diseases.
Cytology, more commonly known as cell biology, studies cell structure, cell composition, and the interaction of cells with other cells and the larger environment in which they exist.
Though biology precedes cytology in its development, cytologists are responsible for our modern view of biology and all other life sciences.

 Vaginal Cytology - WSAVA 2002
The vaginal cytology is typical of estrogens secreted by developing ovarian follicles with RBC, numerous parabasal, small and large intermediate vaginal cells, neutrophils are common, bacteria, and a dirty background in the early proestrus and with no neutrophils, less blood cells, more than 80% of superficial cells and a clear background in the late proestrus.
Vaginal cytology is characteristic in this phase with a dramatic "shift" form a estrus with a 80-100% superficial cells to one of 80-100% of parabasal and intermediate cells plus neutrophils and metestrus cells.
The vaginal cytology is really curious and has a lot of typical characteristics: we can observe all types of vaginal cytology cells, intermediate, squames, parabasal and superficial and again we can see debris in the background.

 Cytology in Small Animal Practice
In human hospitals where cytology is an important diagnostic tool and is routinely used, over 3/4 of surgical lymph node biopsies were prevented by findings of aspiration cytology.
This "instant" cytology sometimes allows the client to make a decision as to disposition of the animal (for example, if the animal has disseminated disease), or may allow the surgeon to make a decision about resection of lymph nodes.
One of the truer statements ever made is that the results of cytology are inversely proportional to the square of the distance between the cytologist and the clinician.

 Unflagging role of urinary tract cytology in monitoring patients with bladder cancer: Currents: UI Health Care
However, both the sensitivity and specificity of voided urine cytology for the diagnosis of high-grade lesions are close to 100%.
New facts: The main argument of the critics of urine cytology is that, regardless of its high specificity (very low number of false positive results), it has an unacceptable low sensitivity (high number of false negative results) as far as diagnosis of superficial low-grade tumors is concerned.
Although they have been targeted as replacement for cytology, most tests are still inferior to cytology, thus, allowing cytology to keep its unflagging role in diagnosing bladder cancer.

 Cytology Proficiency Testing
We note several reasons why cytology PT is not identical to the routine evaluation of patient material, both in terms of the microscopic examination and the reporting of results.
To assess the proficiency of personnel, slides used for cytology PT include a high percentage of abnormal preparations which could be up to 80 percent of the challenges for the testing event, whereas a laboratory's routine patient case load might vary, with abnormal cases representing 5 percent to 25 percent of the total volume.
Under the CLIA cytology PT requirements, each person examining cytologic preparations is tested on his or her ability to categorize each slide into one of four response categories.

 Past now present with cytology PT - College of American Pathologists   (Site not responding. Last check: )
The requirement that laboratories conduct cytology PT was not only included in the law, but also viewed by some as one of its chief purposes because of widespread media attention to Pap testing errors.
CLIA '67 was the genesis of cytology proficiency testing because it set requirements for PT in a variety of laboratory areas, notes R. Marshall Austin, MD, PhD, of Coastal Pathology Laboratories, Charleston, SC.
In cytology, it's very hard to find what people call "classic examples" of slides to review, he says, "because there are so many cells on every slide, and cells in biology are not made on a cookie cutter.
