The Cytology Laboratory is located on the seventh floor of the Shorey
building, room S7/19. The laboratory is open for receiving specimens Monday through
Friday between the hours of 8:00 a.m. and 4:30 p.m. (with the exception of legal
state holidays). A cytopathologist is on call for STAT cases after hours
and on weekends, and can be reached by contacting the Pathology resident on
call (688-2009).
All specimens brought to the Cytology Laboratory should be accompanied by a
Cytopathology Request form which has been properly completed. Cytology requisition forms are available on the UAMS Intranet site #2382 or #622. Current Federal Regulations
(CLIA '88) mandate the information required on each request form to include:
Patient's name
Unit (history) number
Birthdate
Collection date
Physician's name
Source of specimen
Pertinent clinical history
Location of the patient
Specifically for Pap smears include:
Last menstrual period
Previous abnormal report
Previous treatment or biopsy
Every effort should be made to submit specimens
during laboratory hours. In the event that this is not possible, then specimens
should be placed in the specimen refrigerator located next to the Histology
Laboratory on the fourth floor of the Shorey building. Please contact the Cytology
Laboratory, Ext. 686-6540 for instructions on fixation of specimens submitted
after hours. DO NOT TAKE THE SPECIMEN TO THE CLINICAL LABORATORY
IN THE HOSPITAL.
The goal of all
methods for the collection and display of cells is to display the cells under
the optimum conditions for microscopic examination and to utilize as much of
the collection area as possible to display a representative sample of the original
specimen.Pap smears and non-gynecological smears prepared by the clinician should be collected
on 3 x 1, plain glass slides, frosted at one end. The glass should appear colorless,
transparent, and be free of pits, nicks, bubbles, scratches and cloudiness when viewed in
front of a dark surface. The material should be distributed evenly over as much of the
surface of the slide as possible, leaving the frosted end of the slide free for numbering.
Slides should be labeled with patient identifiers at the time of collection, using a #2 pencil on the frosted end of the slide. Immediate fixation of the specimen in 95%
ETOH or with a spray fixative is essential in order to prevent air-drying.
Vaginal and
Cervical Cytology (PAP SMEAR)
The patient should not have douched or applied
medication vaginally 24 hours before the examination.
Have in immediate proximity:
A Thin
Prep pap smear collection vial (PreservCyt solution)
A plastic
broom-like collection device or a plastic spatula and Cytobrush.Wooden spatulas and/or cotton-tipped applicators are not to be used
for liquid-based pap smear collection. Note: This is the preferred collection method. More than 95% of pap smears performed here at UAMS
are liquid-based, mono-layer preparations. Supplies are available in the
Cytology laboratory.)
Place the
patient in the lithotomy position.
Insert the
speculum without lubricants (just warm tap water).
To use the
plastic broom, the long central bristles are inserted into the os until the
lateral bristles bend against the ectocervix and are rotated 3-5 times in
clockwise and counter-clockwise directions.
After
specimen collection, rotate the broom-like device or spatula and Cytobrush
several times in the collection vial to remove the specimen, firmly cap the
vial, and discard the collection devices. Affix a patient identification
label to the vial.
Package the sealed vial in a plastic specimen
bag, along with a properly filled-out cytology requisition form, and send or
deliver it to 7S19.
If liquid-based Pap smear supplies are not on
hand, and a conventional pap smear is to be done, prepare a clean glass slide
marked with the patient’s name. and assemble an Ayre spatula, a cervical brush
or “broom,” and a non-aerosol (pump) spray fixative.
If performing a conventional pap, insert the
spatula into the cervix, rotate it 360 degrees to perform a scraping, and make
a smear lengthwise along one side of a glass slide labeled previously with the
patient’s name.
Insert the cervical brush into the os with
gentle pressure and rotate only 90 to 180 degrees to minimize bleeding. Quickly make an adjacent, lengthwise smear on
the same slide. Immediately fix the smears by spraying with
fixative, held 10-12 inches away from the slide.
Note:Any air-drying will hinder the cytologic
interpretation.
Send to the lab (7S19) in a cardboard or plastic
slide holder along with a properly filled-out cytology requisition form.
(“Broom”: Another collection instrument for Pap Smears is a plastic
“broom-like brush which simultaneously samples the endocervix and ectocervix.
To use the broom, the long central bristles are inserted into the os until
the lateral bristles bend against the ectocervix and are rotated 3-5 times
in clockwise and counter-clockwise directions.)
Collection and
Fixation of Non-Gyn (extra-vaginal) Specimens
Smears
Send to lab in cardboard or plastic slide
carriers, or in tightly sealed tubes of 95% ETOH. Attach completed Cytopathology
Requisition Form with pertinent clinical history. Evenly smear specimen
on clean glass slides labeled with patient's name and record number.
**FIX ANY PREPARED SMEAR IMMEDIATELY IN 95% ETOH OR SPRAY
FIXATIVE.
Body fluids and washings
Send to lab in an appropriately labeled
and well-constructed container with a secure lid to prevent leakage during
transport. If necessary, place container in plastic bag and attach requisition
to outside of bag. Do not send collection needle. Submit complete
Cytopathology Requisition Form with pertinent clinical history.
DO NOT TAKE SPECIMENS TO THE CLINICAL LABORATORY
**Body Fluids and Washings: Specimens should
be submitted fresh, preferably during working hours. If obtained after
hours, place in specimen refrigerator on the fourth floor, Shorey Building.
*Urine: Bring immediately to lab. Requisition should indicate whether specimen is
a catheterized or voided collection
*Sputum: Three separate, early morning fresh specimens obtained on three consecutive
days, sent immediately to lab.
*Bronchoalveolar Lavage
(BAL): Bring the specimen directly to the Cytopathology Laboratory after completing
the procedure. It will be processed and evaluated on a STAT basis only during
regular laboratory hours.
*CSF: ONLY on weekends, holidays, and in emergency cases, take CSF specimens to the Clinical
Lab, marked "Attention Hematology"
They will prepare slides for Cytology.
Preparation
of Cerebrospinal Fluid for Cytology
(WEEKENDS AND AFTER HOURS ONLY)
1. Specimen should be submitted fresh to the
lab as soon as possible.Record amount and appearance on requisition.Centrifuge the entire available specimen
in a 50 ml conical, capped tube for 10 minutes at 2200 rpm.Pour off supernatant down to approx. .5
ml. Add 4 drops of albumin to concentrated specimen and mix.Assemble 4 cytospin funnels in cytocentrifuge.
Divide specimen/albumin mixture in the 4 funnels and cytospin for 2 minutes
at 800 rpms.Quickly disassemble the slides and allow
2 slides to air-dry and spray-fix the other 2.
2. Notify the cytology lab to pick up the prepared
slides.
Procedure
for Fine Needle Aspirations
The cytology service offers
fine needle aspiration of palpable masses. A cytopathologist will see
the patient, perform the aspiration, and provide a rapid interpretation
of the findings. Any need for additional studies, or delay in the final
diagnosis will be discussed when the rapid interpretation is provided.
If aspirated material is needed
for special investigations (flow cytometry, cytogenetics, etc.), this
should be ordered at time of the initial request.
All fixatives, as well as
provisions for special stains or embedding techniques will be provided
by the attending cytopathologist.
Fine needle aspirations can
be scheduled by calling the cytology laboratory at Ext. 501-686-6540,
or the FNA clinic (for ambulatory patients) at 501-686-8064.
Aspiration of deep masses
requiring radiographic guidance should be scheduled with the radiology
department. A cytopathologist attends these procedures.
The following considerations
apply to clinicians wishing to perform their own aspirations:
Laboratory personnel can
provide teaching in the basic methods of specimen preparation.
The type of material most
appropriate for evaluating a given clinical problem varies with the
nature of the lesion, and the preferences of the cytopathologist on
service at the time. Among others, the options include air-dried smears,
fixed smears, needle-rinse material, and embedded samples fixed
in alcohol, glutaraldehyde or formalin. Discussing the case with a
cytopathologist prior to the procedure will optimize your preparation
and the diagnostic results.
Observations made at the
time of the procedure should be noted on the request form. For example,
one often sees abundant colloid when smears from a benign thyroid
mass are prepared, but this diagnostically critical material frequently
"washes away" when the slide is stained.
When a specimen is taken from a patient with suspected or known infectious
disease, the specimen must be submitted properly bagged and labeled
with a Blood and Body Fluids Precautions sticker. For specimens not submitted as outlined, the
physician will be contacted to do so and an incident report will be filed.
All cases are reported utilizing a combination
of message codes and free text as necessary. The report stored in each patient's
lab computer record includes the following:
Name and other demographics
Cytology number
Type of specimen
No. of slides made
Clinical information as provided
Cytotechnologist
Diagnosis

The categories in bold type are reported to
the patient's medical chart as the Cytotechnology Report. An electronically-signed
copy is sent to Medical Records and the original is retained in the Cytology Laboratory files.
Unacceptable
Specimen Criteria
Unlabeled specimens
cannot be accepted. The submitting physician
or nursing station will be notified and will be expected to submit a fresh,
correctly labeled specimen; if not possible, the submitting physician
or nursing station may personally identify and label the existing specimen
and sign a witnessed voucher.
Mislabeled or
misidentified (patient specimen and Cytology Accession Form have different
names) specimens cannot be accepted.
The submitting physician or nursing station will be notified and asked
to submit a fresh correctly labeled specimen; if not possible, the submitting
physician or nursing station personnel may identify and relabel the existing
specimen and sign a witnessed requisition.
Unidentified
