    W TO MAKE A REQUEST FOR

  • 7. HOW TO MAKE A REQUEST FOR ROUTINE HISTOPATHOLOGY

    EXAMINATION OR OTHER HIST OPATHOLOGY SERVICE.

    7.1 General (routine) histopathology.

    Use PER-PAT 301 carbonized request form filled in with relevant clinical information for all

    histopathological examination requests. If the report is needed urgently, please mark the

    request form URGENT clearly at the top right hand corner.

    Histopathology Laboratory requires a set of request form (3 carbonized copies) for each

    request. A request with multiple specimens only requires one set (3 carbonized copies) of

    request form.

    7.2 Frozen section.

    All requests for frozen section examination must be preceded by appointment and discussion

    with the Surgical Pathologist on-call at least 1 day before the operation. This is followed by

    filling up of the request form for the frozen section and submitting it to the Histopathology

    Laboratory for notification.

    Request form for frozen section (HKL/JP/HI/AK-05-02) is available at the Histopathology Office. (Appendix 7 - A).

    Please inform Medical Officer at ext. 6851 or 5603 if the frozen section examination is

    cancelled.

    All cases scheduled for frozen section examination are best placed first in the operating list.

    So it can be done during normal working hours.

    7.3 Clinical autopsy

    Clinical autopsy or postmortem examination is conducted to ascertain the cause of death in

    non-medicolegal cases. This service is only provided for patients who died in Kuala Lumpur

    Hospital.

    The following procedure should be followed:

    1. The requesting doctor shall first obtain written consent from the next of kin.

    Use Borang Keizinan Bedah Siasat Mayat Klinikal (Autopsi Klinikal HKL/JP/HI-BP-02).

    This consent form is available at the mortuary counter of Forensic Department, Kuala

    Lumpur Hospital.

    2. In cases where the next of kin is not available, the Hospital Director and one medical

    specialist will have to give their consent.

  • 3. In case of a foreigner where the next of kin is not available, consent from their respective

    embassy officials is required.

    4. The clinician who requests for post-mortem shall communicate directly with the

    Histopathology Medical Officer or Pathologist on call.

    5. Postmortem examination is usually performed during office hour but requests can be made

    after office hour if necessary.

    6. During office hour, the Medical Officer/ Pathologist on call for clinical postmortem can be

    contacted at extension 6851 or 5603.

    7. After office hour, the Histopathology Medical Officer and Pathologist on call can be

    contacted through telephone. Duty roster of Histopathology Medical Officer /Pathologist

    on call and their contact numbers are available at the mortuary counter of Forensic

    Department (ext. 6695) and hospital operator.

    8. A clinical summary together with the case notes and consent form shall be sent to the

    Medical Officer or Pathologist on duty.

    9. The requesting specialist from the clinical department is required to be present during the

    autopsy.

    7.4 Specialised histopathology services / Referrals

    Histopathology Unit provides specialized histopathology services in areas as listed above.

    Referrals or cases for expert or second opinion are welcome.

    i. For consultation :

    The client (pathologist or clinician) can communicate directly with the Pathologist specialized in the respective field.

    ii. Referral for expert or second opinion:

    For HKL patients that need expert or second opinion, the requesting doctor

    (clinician) is required to fill up the request form as routine cases and submit it to

    Histopathology Laboratory together with the specimen (paraffin embedded tissue,

    stained and/or unstained slides). Paraffin embedded tissue is preferred if the cases

    need further ancillary studies or staining.

    For outside cases, the material together with referral letter should be sent to

    Histopathology Laboratory. The request should be directed or addressed to the

    specific Pathologist depending on the specialty. The report will be emailed to the

    respective department.

    The general referral cases or cases other than the above listed subspecialties will

    be reported by the pathologist on call on that particular day.

    If the case has been reported elsewhere, report should be viewed from system LIS.

  • 8. SPECIMEN COLLECTION AND CONTAINERS

    All specimens for routine histological examination are to be fixed in 10% neutral buffered formalin

    (NBF) in a suitable clean leak-proof container.

    The containers should have wide opening and if possible with screw cap to prevent leakage.

    The volume of formalin used must be at least 10 times the volume of specimen to be fixed. Do

    not put large specimen in small containers as this would prevent proper fixation of the tissue and

    also distort the specimen.

    All specimen containers should have the same identification details as that written on the request

    forms.

    Multiple small specimens such as gastrointestinal biopsies should ideally be mounted on a piece

    of filter paper and immediately put in formalin.

    Specimens from different anatomical sites should be sent in separate containers, properly labelled

    and must be clearly itemized in the request form.

    For cases that require confirmation of the adequacy of surgical excision, the margins of the

    specimen must be marked or tagged accordingly by sutures or by diagrammatic representation

    of the excised specimen.

    Specimen for frozen sections should be sent in a clean container without fixative.

    Specimen for enzyme histochemistry (acetyl cholinesterase) studies is to be sent fresh

    immediately without fixative in closed containers and moistened with normal saline to prevent

    drying.

    8.1 Muscle biopsy

    All requests for muscle biopsy must have prior arrangement with the pathologist concerned or

    Medical Lab Technologist (MLT) at extension 5605 at least one day before the procedure.

    (Usually the biceps or quadriceps muscle would suffice in most cases)

    Important information to be included in the request form are:

    Creatine kinase level

    LDH

    Contact no. of treating clinician relevant hospital fax number x Family history of

    similar problems.

    For open biopsy:

    Remove at least one good cylinder of muscle measuring 1.0x0.5x0.5 cm, the

    smaller diameter being the cross-section of the muscle.

    For optimal processing muscle specimen must be wrapped with aluminum foil

    and sent fresh in an air tight, dry and clean container.

  • The specimen should be transported in a container containing ice or gel ice.

    (Never use dry ice).

    Do not tie the muscle to stretch it and do not put tissue on gauze.

    The laboratory will accept fresh muscle biopsy specimen up to 4 hours upon removal but

    please remember that optimal result requires the specimen to be as fresh as possible.

    8.2 Renal biopsy

    Prior arrangement with the Pathologist concerned is preferred for very urgent requests.

    Two specimens are recommended for each case for proper histopathological evaluation, i.e

    formalin fixed tissue for ordinary light microscopy examination and fresh tissue for

    immunofluorescent staining.

    Renal biopsy tissue for immunofluorescence:

    Take at least 5 mm core of fresh tissue.

    The specimen should be sent fresh in a clean air tight

    container.

    If the specimen cannot reach the laboratory immediately, the

    fresh tissue should be put in phosphate buffer, properly

    packed and transported in ice or gel ice.

    Do not put fresh tissue specimen on gauze.

    9. DESPATCH AND TRANSPORTATION OF HISTOPATHOLOGY SPECIMEN

    Specimens for routine histopathological examination should be sent in formalin to counter no. 5,

    common receiving area (CRA) of Pathology Department.

    Fresh tissue specimen for frozen section, immunofluorescent staining and enzyme histochemistry

    such as muscle biopsy should be sent immediately to Histopathology Laboratory.

    Fresh tissue should be properly packed and transported in ice or dry ice if the specimen cannot

    reach the laboratory immediately (especially specimen from other hospitals).

    For frozen section, the specimen should be sent immediately upon removal to Histophatology

    laboratory (Pintu 6). by a doctor who will wait for the report.

    Muscle biopsy specimen should be sent to Histopathology Laboratory (Pintu 6).

  • 10. HISTOPATHOLOGY REPORTS

    Reports of small biopsies for histopathological examination which are labelled ‘urgent’ will be

    available within 1 week after the specimens were received by the laboratory. Exception are cases

    sent in more than 4 containers, and/or require further ancillary studies.

    NOTE: Please leave the requesting doctor’s name and contact number on the request form for

    early flagging of results.

    Results of frozen section will be immediately communicated to the surgeon via telephone or the

    doctor who brought the specimen to the laboratory within 1 hour.

    10.1 Access to HPE reports

    For clinics / wards / departments within HKL, HPE reports can be accesses via

    Doctor2U laboratory informative system. For others (non-HKL), reports will be emailed to

    the respective departments.
