Procedure for Submitting Surgical Specimens
Specimens should be transported observing UNIVERSAL PRECAUTIONS, OSHA (29 CFR
1910.1030), "treating all body fluid/materials as if infectious." EACH SPECIMEN
SHOULD BE ENCLOSED IN AN IMPERVIOUS CONTAINER WHICH HAS BEEN EXAMINED CAREFULLY FOR LEAKS
BEFORE TRANSPORTING.
1. Tissue samples obtained at the operating room, clinics and the
floor should be submitted in containers of 10% buffered neutral formalin pH 7, labeled with the name of
the patient, DATE OF BIRTH, unit number, account number, and tissue
identification.
2. Each specimen jar should
be accompanied by a requisition form containing the same information inscribed
on the container, a short clinical history, ORDERING PHYSICIAN'S NAME (physician
must have hospital admitting privileges), and location code (nursing station
or clinic).
3. All tissues should be
forwarded as fast as possible to the Surgical Pathology Department, fourth
floor, Shorey Building, to the receiving area, 4S/22.
4. All specimens received
prior to 3:30 p.m. are processed with the expectation of providing a typed
report by 5:00 p.m. the next day. Exceptions are instances where special studies
or complex dissection has to be performed. In some of these cases a provisional
diagnosis can be obtained by calling 66537.
5. The validity of requests for specimens to receive accelerated
processing, requiring a
report the same day or by 9:30 a.m. the following day must be assessed jointly
by the pathologist and the physician requesting such service.
6. Large specimens originating
from the operating room should be sent to the Surgical Pathology Laboratory
unfixed. Do not mutilate or attempt to dissect such a specimen. If you would
like to know gross detail, contact the Pathology Department at Ext. 66537.
A pathologist will be available to dissect the specimen and show it to you.
7. When a case of gout is suspected, the tissue should be sent to the Surgical Pathology Laboratory
in absolute alcohol. Uric acid crystals dissolve in formalin.
8. Should you feel the gross
specimen may not reach the Surgical Pathology Laboratory soon enough to prevent
autolytic changes, e.g., after 4:30 p.m. or on weekends or holidays, it should
be fixed in formalin or placed in the specimen refrigerator located in the
hallway between 4S/12 and 4S/22.
9. DO NOT LEAVE FRESH, UNFIXED TISSUES AT ROOM TEMPERATURE.
10. In the event after hours consultation is needed, please
call the Pathology Resident on beeper 688-2009.
UNACCEPTABLE SPECIMEN CRITERIA
1. 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.
2. Mislabeled or misidentified
(patient specimen and S/P 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 voucher.
3. Unidentified specimens (cases
in which the specimen is labeled with the patient's name, but contains no
identification of specimen type or source). These specimens cannot be
accepted until the physician or nursing station is notified. The specimen
will then be dictated and documented as received unidentified.
4. Specimens submitted improperly
(not in compliance with OSHA (29 CFR 1910.1030) cannot be accepted. The
submitting physician or nursing station will be notified and will be expected
to retrieve the specimen and submit it correctly.
5. Specimens not accompanied by a Surgical Pathology Accession
Form cannot be accepted.
6. Incorrect
Accession Form (tissue specimens received with an accession form from another
patient service, e.g., Microbiology) cannot be accepted.
7. Soiled Accession Forms (tissue
specimens received with an accession form soiled or wet with fixative, blood
or any other fluid). The submitting physician or nursing station will
be notified, requested to prepare a clean Accession Form and sign an Incident
Form.
8. Other conditions for non-acceptance
include: insufficient quantity of specimen containers received "empty",
improper storage (i.e. incorrect fixative, no fixative, not on ice, etc.).
These specimens will not be accepted until the submitting physicians or nursing
station is notified.
An internal Specimen Incident Form is completed for appropriate
documentation and noted in gross description of the Specimen.
FROZEN SECTION CONSULTATIONS
1. During regular hours the need for a frozen section
consultation should be forwarded to the
Surgical Pathology Department, extension 66537.
2. Fresh
tissues should be placed on a green towel, moistened with isotonic saline
and enclosed in an impervious plastic bag for transportation to the frozen
section room, 4S/22, located on the fourth floor of the Shorey Building.
3. A courier will collect the specimen and
requisition form. The Pathologist will interact by
telephone with the surgeon or physician performing the surgery.
4. All frozen section consultations must be
accompanied by a Pathology Requisition containing
the following information: Patient name, account number, date of birth, unit
number, tissue
identification, attending physician's name and a short clinical history. PLEASE
INDICATE IF THE
PATIENT IS AWAKE AND O.R. NUMBER.
5. DO NOT TRANSPORT TISSUES ON GAUZE OR SUBMIT TISSUES
IN FORMALIN.
6. In the
event of after hours consultation, please call the Pathology Resident on Pager
688-2009.
LYMPH NODE TO RULE OUT LYMPHOMA
Handle the specimen as frozen section consultation. Specimen must be submitted
fresh.
PROCEDURE FOR KIDNEY NEEDLE BIOPSIES
1. Obtain a needle biopsy,
preferably 2 cm or more in length, or an open wedge biopsy.
2. Using renal biopsy service kit (obtain from UAMS Pathology, Room
4S/22c, Ext. 66537):
a.
Place one portion of kidney biopsy in LM-EM fixative.
b.
Place remaining portion of kidney in I.F. transport media.
c.
Complete UAMS Accession Form:
Patient name
Account number
Date of birth
Ordering physician
Specimen I.D.
Date of procedure
Short clinical history and services required
3. Transport immediately to John L. McClellan Memorial Veterans
Hospital, Room 2E-141, for processing.
4. Where tissue is adequate, light and electron microscopy
and direct immunofluorescence are performed on all renal biopsies. Where technical
difficulties prevent an adequate specimen of tissue from being obtained, the
selection of techniques should be decided jointly by the pathologist and attending
physician.
MUSCLE BIOPSY FOR HISTOCHEMISTRY
Section: Histology
Request Form: Surgical Pathology
Specimen Required: Minimum of 1 cm square of fresh muscle - do not tie down or
divide into pieces
Routine Hours Offered: 8:00 a.m. - 4:30 p.m., Monday-Friday
Test Information:
Muscle Histochemistry includes a battery of nine stains plus a paraffin H & E. The
muscle is divided within our laboratory - it should never be sent in more than one
portion. Once received, two portions are quick frozen for the Histochemical stains, a
sample is saved for Electron Microscopy and a portion is routinely processed through
paraffin. Electron Microscopy is not done routinely; it is only performed when
indicated by the pathologists.
Transportation of Specimen:
The specimens should be sent in a timely fashion in a specimen container. That container
should be placed on ice. Never put the specimen directly on ice. This causes
freezing artifacts, which render the specimen useless. The specimen may be wrapped in a
gauze pad slightly moistened with saline. It should never be submerged in saline,
as this also causes freezing artifacts. Each specimen and accompanying requisition should
contain the following information: patient name, date of birth, account number, service,
attending physician and tissue identification. In addition, the requisition should contain
a brief clinical history, pre- and postoperative diagnosis.
Please notify the lab when sending a muscle biopsy at 686-6537.
PROCEDURE FOR IMMUNOFLUORESCENT
STUDIES (INCLUDING STAINS FOR LIGHT AND HEAVY CHAIN DEPOSITION
1.
Tissue submitted for immunofluorescence should be forwarded to the Surgical
Pathology Laboratory, room 4S/22, immediately in fresh state, contained
in an impervious container (clean specimen cup or plastic bag).
2. DO NOT FIX THE TISSUE IN FORMALIN OR FREEZE.
3. It is advisable to call
the Surgical Pathology Department, extension 66537, ahead of time to advise
the personnel of the procedure.
4. Each sample should be
accompanied by a requisition form bearing the patient's name, date of birth,
account and unit numbers, requesting physician, a short clinical history and
specimen identification.
5. Endomyocardial biopsies for myeloma patients only should be handled as other specimens which
are submitted for Immunofluorescent studies. Please notify Mr. Mike Davis
(688-9274) as soon as possible.
BONE MARROW BIOPSY FIXATION PROCEDURE
See Clinical Laboratory section.
ESTROGEN/PROGESTERONE RECEPTOR ANALYSIS (ER/PR)
If an invasive breast carcinoma is detected at the time of gross or microscopic
examination by the pathologist, he or she will automatically order ER/PR. The results will
be available within 7 working days.
REPORTING RESULTS
1. All results, unless complicated
and/or requiring special stains or consultations, will be completed and signed
by the Pathologist 24 hours following the receipt of the tissue.
2. The pathology staff is available at any time for consultation.
3. Questions and matters concerning a report should be addressed to
the receptionist's room,
4S/12, telephone extension 65172, between 8:00 a.m. and 4:30 p.m. The receptionist's
office is closed on weekends.
4. Any questions regarding
diagnostic matters should be directed to the pathologist who initially signed
the report. If further consultation is needed, another pathologist can also
be
contacted providing, as a matter of courtesy, the pathologist responsible
for the case is notified.
SPECIAL HANDLING
Exceptionally, and only when it is necessary
to obtain vital information, the Department of Surgical Pathology is willing
to process tissues or perform special techniques after 4:30 p.m. or on an
emergency basis. The establishment and validity for such a request is assessed
jointly by the pathologist-on-call and the physician requesting the procedure.
ELECTRON MICROSCOPY
Because of the high degree of expense and technical effort involved,
all specimens must be approved for electron microscopy (EM) by a faculty member of the
Department of Pathology. Generally, this will be the person with responsibility for the
routine surgical pathologic examination of the specimen in question (686-5172). The
faculty member will be responsible for examining the tissue in a fresh state, selecting
suitable areas for ultrastructural examinations, fixing the material. The same faculty
member is also responsible for examining the semi-thin sections and electron micrographs
from the E.M. Lab and for reporting a diagnosis.
A. Responsibility of Requesting Clinician:
Clinicians desiring E.M. studies on a specimen should contact a pathology
faculty member before the biopsy is taken. It is essential that the specimen for E.M.
be delivered to Pathology immediately after removal from the patient. Delay
in fixation of more than a few minutes may result in an unsatisfactory study.
B. Responsibility of Resident "on" Pathology:
Residents involved in the gross examination and dissection of surgical specimens
are responsible
for recognizing cases in which E.M. may be indicated. These cases are to be
sampled, fixed, and
stored; the faculty pathologist responsible for surgical pathology will decide
if E.M. studies are
warranted.
C. Specimen Examinations for Scientific/Academic Purposes
For most specimens handled by the E.M. Lab the ultrastructural findings will
bear directly on
the patient's diagnosis and treatment. Some pathologists, clinicians, or basic
scientists may
wish to examine specimens to further scientific research or their education.
These specimens
will be clearly designated as such and no charge will be made to the patient
for these studies.
D. Inquiries:
Questions regarding E.M. Lab procedures should be directed to the E.M. Lab
