GYNECOLOGIC SPECIMENS
Thin PrepÒ Pap TestÔ
Indication:
Sampling of the superficial cells of the cervix, endocervix and/or vagina to detect premalignant
and malignant lesions of the uterine cervix and other abnormalities of the
reproductive tract. The Thin PrepÒ Pap TestÔ is intended as a
replacement for the conventional method of Pap smear preparation. Studies have shown that this procedure
decreases fixation artifacts, provides a more uniform specimen for microscopic
evaluation and increases the yield of abnormal cells.
Supplies:
Vaginal speculum, * Thin PrepÒ Collection Kit (which includes plastic
spatula and brush or broom device, and PreservCytÒ Solution vial), *LMC gynecologic cytology
requisition form, *biohazard bag for specimen transport. (*items provided by LMC)
Please note the following Thin PrepÒ Pap TestÔ important information:
·
Wooden spatulas cannot be used for the Thin PrepÒ Pap TestÔ. The wood is porous and cellular material will
stick to the collection device and not be transferred to the collection
vial. The Thin PrepÒ Pap TestÔ is only FDA approved for
use with the plastic spatula device, brush or broom device.
·
Caution: PreservCytÒ solution contains methanol,
which is poisonous and may be fatal or cause blindness if swallowed. Vapor is harmful if inhaled. This solution causes eye and skin
irritation. PreservCytÒ is flammable: keep away from fire, heat, sparks and
flame. Other solutions must not be
substituted for PreservCytÒ solution. PreservCytÒ should be stored and
disposed of in accordance with local, state and federal regulations. Check the expiration date on the vial prior
to use. The laboratory cannot accept
samples in expired PreservCytÒ solution.
Requisition form:
Submit all patient information following the procedure
for “Completing a Gynecologic Cytology Requisition” (page 27).
Collection Procedure:
In premenopausal
patients, obtain specimen during second half of menstrual cycle (if possible)
to avoid obscuring blood. Instruct the
patient not to douche or engage in sexual intercource
within 24 hours of the procedure
1. Print the patient’s name
(last, first) on the PreservCytÒ solution vial. The laboratory CANNOT accept unlabeled
specimens. Check the expiration date to
be sure the solution has not expired.
The laboratory CANNOT accept specimens in expired solution
vials.
2. Place the patient in the lithotomy position.
Using a speculum lubricated with warm water, expose the cervix as fully
as possible. DO NOT use lubricant
as this will interfere with the cytologic evaluation.
3. If excess mucus, exudates or
blood is present at the cervical os, remove with a
folded gauze pad or large cotton-tipped swab.
4. SPATULA/BRUSH
TECHNIQUE: Obtain an adequate sample
from the ectocervix (and transition zone if visible)
by rotating the plastic spatula device five times around the circumference of
the cervix. Rinse the spatula in the PreservCytÒ solution vial by swirling
the spatula vigorously 10 times in the vial.
Discard the spatula. Obtain an
adequate sample from the endocervix by inserting the
brush device into the cervix until only the bottom most fibers are
exposed. Slowly rotate ¼ to ½ turn in
one direction. DO NOT OVER ROTATE. Rinse the brush in the PreservCytÒ solution by rotating the device in the
solution while pushing against the wall of the vial. Rotate 10 times. As a final step, swirl the brush vigorously
to further release material. Discard the
brush.
BROOM TECHNIQUE: Obtain an adequate sample from both the ectocervix and endocervix
simultaneously by inserting the center
of the device into the cervical os until gentle
resistance is felt and the outer-most tips of the broom are flat on the ectocervix. Push
gently and rotate the broom five times, in a clockwise direction, 360 degrees
around the os.
Rinse the broom in the PreservCytÒ solution vial by rotating the device in the
solution 10 times, pushing the bristles of the broom against the bottom and
edges of the vial (like rinsing a paint brush)
to dislodge the material. Discard
the broom. DO NOT cut off the end
of the collection device and leave in the vial.
The cellular material will harden onto the device and not effectively
transfer to the solution.
5.
Tighten the cap on the PreservCytÒ solution vial so the torque line on the cap
passes the torque line on the vial.
6.
Use the specimen collection biohazard bags provided by LMC. Place the completed requisition in the
outside pocket and the properly labeled PreservCytÒ solution vial in the zip lock portion of the
bag. Send to Laboratory Medicine
Consultants for processing. The
laboratory CANNOT accept unlabeled vials or specimens without a properly
filled out requisition form.

the proper collection technique used for the Thin PrepÒ Pap TestÔ, please contact Laboratory
