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 receiving area, B007.
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.
9. DO NOT LEAVE FRESH,
UNFIXED TISSUES AT ROOM TEMPERATURE.
10. If an after hours consultation is needed, please call
the Pathology Resident on pager 658-8313.
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, B007.
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 658-8313.
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 B007, 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 B007, 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, telephone
extension 686-5172, 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.
