GENERAL INFORMATION:
Please fill out the request form completely to include
the patient's full name, sex, age, date of birth, social security
number, date specimen obtained, location of biopsy, submitting doctor/clinic,
clinical information including diagnoses and demographic/billing
information.
LABELING:
All specimen containers should be labeled with the patient's name,
date collected and identity/location of tissue.
(NOTE: SPECIMENS OBTAINED FROM DIFFERENT LOCATIONS ON THE SAME PATIENT
MUST BE PLACED IN SEPARATE CONTAINERS.) Slides should be labeled
with the patient's name.
TISSUE BIOPSIES:
Tissue biopsies should be placed in 10% buffered formalin for routine
histologic studies. The formalin volume should be at least 5 times
the volume of the tissue.
CURETTINGS - Endocervical
and endometrial curettings may be placed on Telfa pads to absorb
blood. This makes it easier to recover all of the tissue fragments
for processing.
FROZEN SECTION - Biopsies
for frozen section should be delivered FRESH to the laboratory
immediately for examination by the pathologist. Please designate
margins of resection if needed by ink or sutures. Call to schedule
in advance.
LYMPHOMAS:
Lymph node and other tissue specimens with clinical suspicion for
lymphoma should be delivered FRESH to the laboratory on saline soaked
Telfa, as soon as possible. These specimens should NOT be submitted
in formalin. Special fixation and processing of fresh tissue for
lymphocyte marker analysis are required for the diagnosis of lymphoma.
BONE MARROWS:
Submit bone marrow biopsy and aspirate clot in B5 for optimal fixation.
Touch preps of the biopsy and aspirate smears should be submitted
fresh, unstained in a separate plasic bag from the B5. B5 fumes
will alter staining of touch preps and smears and must be kept separate.
To maximize clinical pathologic correlation, include a recent peripheral
blood smear and CBC data or an EDTA tube of peripheral blood. If
cytometric flow studies or cytogenetics are desired, send additional
aspirate in lithium heparin (green top tube).
SPECIAL HANDLING:
Call the laboratory for special handling instructions on skin biopsies
for immunoflourescence, kidney, muscle or nerve biopsies.
Call San Diego Pathologists at 619.297.4900 and
request courier pickup or supplies.
