'What happens during a pap smear and why is it important for women to get it?'

The Pap (Papanicolaou) Test The Pap test is a procedure that collects cells from the cervix so that they can be looked at closely in the lab to find cancer and pre-cancer. How the Pap test is done The health care professional first places a speculum inside the vagina. Papanicolaou test (smear) [ pap?ah-nik?o-la?oo] a simple, painless test used most commonly to detect cancer of the uterus and cervix; it is based on the discovery by Dr. George N. Papanicolaou (–) that malignant uterine tumors slough off cancerous cells into surrounding vaginal fluid. Called also Pap test and Pap smear.

It is a polychromatic stain containing multiple dyes to differentially stain various components of the cells. This technique was developed by George Papanicolaou, the father of Cytopathology. This method is used to differentiate cells in the smear preparation of various gynecological specimens pap smearsmaterials containing exfoliative cells and material from fine needle aspiration. Papanicolaou stain includes both acidic and basic dyes.

What can a couple do for fun with no money dye stains the basic components of the cell and basic dye stain the acidic components of the cell. Both progressive and regressive nuclear staining what is in fun snaps can be used in Papanicolaou stain.

In the progressive method, the nucleus is stained with hematoxylin to a intensity desired. The intensity of the nuclear staining is controlled by the immersion of the slide into a blueing agent. When using the regressive staining method, the nucleus is deliberately over-stained with a non-acidified haematoxylin. The excess stain is removed with dilute hydrochloric acid solution acid water.

The decolourising process is then stopped by immersing the slide in running tap water. Timing is crucial in the regressive method as de-staining may lead to a hyperchromatic nucleus becoming hypochromatic.

You should have mentioned the basic system for concluding the results for carcinoma, as its used mainly for cancer diagnosis. Findings in exfoliative cytology- 5 classes Class 1 normal Class2 atypical Class 3 intermediate Class 4 suggestive carcinoma class 5 positive for cancer. If you have all dry cells you will loose all stainig criteria and end up with brown smear and nothing to diagnose.

Your email address will not be published. Transparency of cytoplasm : This is of particular importance because of the varying thickness and the frequent overlapping of cells. Differentiation of cells : Differences in the staining reaction such as that between acidophilic and basophilic cells help greatly in the identification of certain cell types found in smears. The polychromatic PAP stain involves five dyes in three solutions. Hematoxylin : Natural dye hematoxylin is the nuclear stain which stains cell nuclei blue.

It has affinity for chromatin, attaching to sulphate groups on the D. Orange Green 6 : This is the first acidic counterstain cytoplasmic stain which stains matured and keratinized cells. The target structures are staine d orange in different intensities. Eosin Azure : This is the second counterstain which is a polychrome mixture of eosin Y, light green SF and Bismarck brown.

Eosin Y gives a pink colour to cytoplasm of mature squamous cells, nucleoli, cilia and red blood cells. Staining solutions commonly used in cytology are EA 31 and EA 50, while EA 65 Light green SF stains blue to cytoplasm of metabolically active cells like parabasal squamous cells, intermediate squamous cells and columnar cells.

Bismarck brown Y stains nothing and sometimes it is often omitted.

Sep 09,  · Papanicolaou stain is also known as the pap stain and the procedure of the stain is known as a pap smear. It is a polychromatic stain that uses multiple dyes to differentially stain various components of the cells. It is a histological and cytopathological staining technique used to differentiate cells in a smear preparation. Feb 26,  · A Pap smear, also called a Pap test, is a screening procedure for cervical cancer. It tests for the presence of precancerous or cancerous cells on your cervix. The cervix is . Jan 12,  · Papanicolaou stain (also Papanicolaou’s stain or PAP stain) is the most important stain utilized in the practice of Cytopathology. It is a polychromatic stain containing multiple dyes to differentially stain various components of the cells. This technique was developed by George Papanicolaou, the father of Cytopathology.

Cellular material is collected and smeared on a glass slide. When suspicious cells are identified, further testing may be performed on the same sample. Testing for human papilloma virus HPV is often performed if results show abnormal changes of uncertain significance. HPV is the primary risk factor for cervical cancer. See: illustration. Since the introduction of the Pap test, death from cervical cancer in the U. Although interpretation of the test is subject to human error, a variety of developments have improved test accuracy, including use of computer-generated procedures for detection and examination of abnormal cells and mandated reexamination of sample batches to test quality control.

A woman may augment the accuracy and value of the Pap test by following these guidelines: Asking her health care provider about the quality of the laboratory evaluating the results; having an annual Pap test beginning by age 21 or when the woman becomes sexually active; scheduling the test during a time when she does not expect to be bleeding; abstaining from sexual intercourse and and putting nothing in her vagina; providing a detailed medical history, including use of birth control pills or other exogenous hormones and results of past Pap tests; and requesting a second opinion on the Pap test if she is at risk for cancer of the reproductive tract.

Annual Pap testing should continue until age After age 30, the ACS says women can reduce test frequency to every 2 to 3 years if their health care provider uses the newer liquid-based Pap tests, which include human papillomavirus HPV typing. In young, sexually active women, certain types of HPV cause precancerous changes that can lead to cervical cancer.

Women who have had a hysterectomy for benign conditions and who do not have a cervix no longer need to undergo screening. Screening can stop at age 65 or 70 for those women who have never had positive findings on previous examinations, as long as they have no new risk factors for cervical cancer. Certain women are at high risk for cervical cancer and may need more frequent testing than the general population.

These include women with HPV, chlamydial, or HIV infection and those who are immunosuppressed as a result of other illnesses. Additional risk factors for cervical cancer include early age at first intercourse, a history of sexually transmitted illnesses, cigarette smoking or substance abuse, a previous history of cervical dysplasia, a history of multiple sexual partners, or having a sexual partner who has other partners with cervical cancer.

Because Pap testing has been effective in detecting the early stages of cervical cancer, health care professionals should advocate this procedure for their female patients and participate in health promotion efforts to increase the number of women who have the test done regularly.

It can be performed on any body excretion urine, feces , secretion sputum, prostatic fluid, vaginal fluid , or tissue scraping as from the uterus, cervix, or stomach. The sample is removed from the area being examined, placed on a glass slide, stained, and then studied under a microscope for evidence of abnormal or cancerous cells. In five minutes the Pap test can reveal uterine or cervical cancer at a stage in which it produces no visible symptoms, has done no damage, and usually can be completely cured.

It is recommended that all women over age 18, and younger women who have been sexually active, should have an annual Pap test and pelvic examination. Pap smear. From Lammon et al.
