Smear the sample on another slide, spreading the material evenly over the slide. Spray with fixative immediately. Allow the slides to dry completely before placing them in the Pap smear container.
Which fixative is used to fix a Pap smear slide?
Immediately drop the smeared slide gently into the bottle of 95% ethanol fixative or spray it before it has a chance to air dry.
How do you fix cytology smear?
The most commonly used fixatives for diagnostic pathology and cytologic specimens are 10% NBF and 95% ethanol [3]. In our institution, 96% alcohol used by clinicians as a fixative for cytology specimens because of its accessibility and affordability.
How do you perform a Pap smear spatula?
Obtain an adequate sampling from the ectocervix using a plastic spatula by placing the rounded tip of the spatula into the cervix until the curved edge of the spatula rests against the ectocervix. Rotate the spatula 360 degrees.
How do you set up a Pap smear?
How you prepareAvoid intercourse, douching, or using any vaginal medicines or spermicidal foams, creams or jellies for two days before having a Pap smear, as these may wash away or obscure abnormal cells.Try not to schedule a Pap smear during your menstrual period.
What are the methods of fixing a smear?
The fixation procedure is the same regardless of smear source, plate or broth. There are two methods of adhering your bacteria to the slide, heat fixation or methanol fixation.
What does fixing the smear mean?
The purpose of making a smear is to fix the bacteria onto the slide. Fixing the bacteria will preserve the morphology of the cells long-term. Also, fixation assists the cells in adhering to the slide, so that the cells do not fall off the slide during the staining procedure.
How can I make my Pap smear more comfortable?
If you'd like to make the test more comfortable, you can:Time your Pap smear around the middle of your menstrual cycle.Ask to shift positions if you feel uncomfortable at any point.Focus on slow, relaxed breathing.Take an over-the-counter pain medication beforehand, if you're concerned about pain.
Which spatula is used for cervical smear?
Wooden and plastic spatulas perform equally well for conventional Pap smears. Plastic spatulas are recommended for liquid-based Pap smears, because cervical cells wash off of plastic more easily than wood. Cotton swabs yield far fewer endocervical cells than do brushes.
Does a Pap smear touch your cervix?
The doctor will gently touch the cervix with a small brush to pick up cells from that area. Some girls say it feels like a pinch. After the doctor or nurse has collected the sample and removed the speculum, you'll be left alone to get dressed.
What goes on a Pap smear tray?
Complete kit contains a plastic speculum, cervical scraper, two 6″ polyester-tipped applicators, pair of latex gloves, lubricating jelly, two frosted end slides, slide holder and mailer.
What fixative is usually used in cytology smear?
Ethyl alcoholEthyl alcohol (95%) is the most commonly used fixative in cytology. The cytology samples are processed commonly by direct smear, centrifugation, cytocentrifugation, liquid-based preparation, Millipore technique and cell block.
Why do we fix in cytology?
Immediate fixation of cytology specimens is critical to the preservation of the cellular components. It is important that no air-drying occurs prior to fixation. If a smear is already air- dried it should NOT be put in alcohol fixative.
What is cytology fixative?
Cytology Fixative covers cells with a tough, soluble film that protects cell morphology for microscopic examination. It is water and alcohol soluble, environmentally friendly and extremely economical.
What is fixation in cytology?
In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues' mechanical strength or stability.
What to tell your doctor about pap test results?
Tell your doctor about any medicines you’re taking. Some kinds of medications, like hormonal birth control pills, can affect your pap test results. Give your doctor a full list of any medicines or supplements you use so that they can interpret your test results as accurately as possible. [9]

When to schedule a pap smear?
Schedule the test when you won’t be having your period. Since bleeding can make the test a little less accurate, try to get your pap smear done during a time when you won’t be having your period. [2]
Why do doctors put lubricant on their fingers?
Your doctor will be wearing gloves and will put lubricant on their fingers to make this process more comfortable for you.
How to fix more than one slide?
Fixation: If more than one slide is immersed in fixation solution, attach a paper clip to each slide to separate slides and allow adequate fixation. Spray fixation with cytospray fixative is preferred.
Can lubricating jelly be used on vaginal speculum?
Failure to obtain adequate ectocervical, endocervical, or vaginal cell population is suboptimal for evaluation. Excessive use of lubricating jelly on the vaginal speculum will interfere with cytologic examination and may lead to unsatisfactory Pap results. All powder should be wiped off gloves before spatulas are handled since presence of starch granules will make interpretation of slides difficult. Inflammatory reaction may preclude hormonal evaluation. A very significant proportion of adenocarcinomas of endometrium are not detected by this means. Occasionally, highly differentiated adenocarcinomas of endocervix can be missed. Occasional aggressive lesions of squamous epithelium of cervix can be missed, especially if patient has only a single examination.
Can you use a posterior vaginal fornix as a cervical specimen?
Aspiration of posterior vaginal fornix (vaginal pool) may also be used but is not a substitute for cervical specimens. Endometrial aspirations are not advised for routine use. For lesions of the vagina or vulva, scrapings made directly from lesion are desirable.
Can adenocarcinomas be missed?
A very significant proportion of adenocarcinomas of endometrium are not detected by this means. Occasionally, highly differentiated adenocarcinomas of endocervix can be missed. Occasional aggressive lesions of squamous epithelium of cervix can be missed, especially if patient has only a single examination.
Can slides be stored indefinitely?
Maintain specimen at room temperature. Slides may be stored indefinitely when spray fixed.
Does LabCorp charge for a slide?
In these cases, LabCorp will charge for the associated service. (Slides that are routinely reviewed by a pathologist for quality control purposes are not included.)
How to do a FNA with no core?
If a FNA is being done and no core is obtained a drop of specimen is placed on a glass slide and it is smeared with another slide via the direct smear method. (See procedure on this page) This results in two slides containing specimen. One slide is allowed to air dry and the other is placed in a slide holder containing 95% alcohol. The rest of the specimen is put into a jar of cytolyt solution. As mentioned above, if one site is being aspirated multiple passes of specimen can be placed in the same cytolyt jar. If more than one site is being aspirated they must be collected separately. Keep this in mind with the slides you prepare and make sure you label properly to avoid confusion.
What is a cytology specimen?
Cytology: A specimen is ordered as a "cytology" when no core biopsy has been obtained. This is when the aspirate is used to make cytology smears and placed in the cytojar ONLY. Examples of cytology specimens include fine needle aspirations of thyroid, pancreas, cysts etc.
What is a surgical pathology specimen?
Surgical Pathology: A specimen is ordered as a "surgical pathology" specimen when a core biopsy has been obtained.Even if slides are made and a cytojar is used along with the core biopsy, it is still ordered as a surgical pathology. Examples of surgical pathology specimens include lung, liver, and GI biopsies collected in formalin, with a needle wash in a cytojar and smears made.
Why is proper fixation important in cytology?
Proper fixation is essential when it comes to analyzing cytology specimens. If a specimen is not collected appropriately, the diagnosis is compromised. The goal of the laboratory is to provide quality patient care and by following these tips we can decrease the number of "indeterminant" diagnoses.
Why is rapid assessment important?
If there is too much specimen the smear appears thick and unreadable under the microscope. Ideally, you want to have a thin, even layer of specimen across the slide. This is another reason that rapid assessment is beneficial; so that poor preparation of the specimen does not render a non diagnostic result.
What is the best way to assess thyroid FNA?
Particularly for thyroid FNAs, on-site rapid assessment is recommended. Having a cytotechnologist or pathologist there during the procedure ensures that an adequate amount of material is collected. This keeps the patient from having to repeat a procedure if the initial FNA was non diagnostic. If you are interested in on site rapid assessment please contact me.
Why is it not safe to add cytolyt to a specimen?
If a specimen is being split amongst various departments it is safer not to add cytolyt because this can inhibit testing in certain instruments in other areas of the laboratory. Inquire with the other laboratory departments if they can process specimens that are fixed with cytolyt solution.
