cytology

 [si-tol´o-je]
the study of cells, their origin, structure, function, and pathology. adj., adj cytolog´ic.
aspiration biopsy cytology (ABC) the microscopic study of cells from superficial or internal lesions obtained by aspiration biopsy.
exfoliative cytology microscopic examination of cells desquamated from a body surface or lesion, done to detect malignancy or microbiologic changes, to measure hormonal levels, and for other purposes. The cells may be obtained by such procedures as aspiration, washing, smear, and scraping, and the technique may also be applied to secretions such as sputum, urine, abdominal fluid, prostatic secretions, and vaginal secretions.

cytology

[sītol′əjē]
Etymology: Gk, kytos + logos, science
the study of cells, including their formation, origin, structure, function, biochemical activities, and pathological characteristics. Kinds of cytology include aspiration biopsy cytology and exfoliative cytology. Also called cell biology. cytologic, cytological, adj.

cytology

Cell biology
The biology of structure, function, multiplication, pathology, and history of cells. In the working parlance, “cell biology” is preferred to “cytology,” given the obvious potential for confusion with health professionals (cytologists and cytotechnologists) who examine cell specimens to render clinical diagnoses. Those who study such phenomena are called cell biologists, not cytologists.

Medspeak
The formal discipline in which cells are studied and the changes seen correlated with the clinical findings in patients.
 
Pathology
The microscopic examination of body fluids for the detection of disease; in cytology, the most common specimen is the Pap smear, a normal component of a gynaecologic examination which is the best means of detecting early, curable stages of cancer of the uterine cervix—formerly the most common cause of death in sexually active women—as well as viral, fungal and other infections of the female genital tract. Cytology specimens can be obtained from various fluids (urine, CSF, or sputum or discharges) specifically as a means of detecting abnormal or malignant cells.

cytology

1. The study of cells.
2. An abbreviation of the phrase ‘exfoliative cytology’ the examination of isolated cells, obtained from cervical smears, sputum or elsewhere, to determine whether or not they are cancerous.

cytology

the study of cells.

cytology 

A study of cells to detect diseases. The usual procedure is to obtain a sample, to fix it on a glass slide, treat it with various dyes and inspect it under a microscope. Differential staining allows identification of the cells and their state of health.
