IRIS BIOPSY

For histopathological examination for suspected neoplasia, particularly pigmented lesions.

1. Thin flimsy iris specimens need to be fixed flat before being sent to the laboratory.

2 Use the Sandwich Press method demonstrated in this 3 minute video https://youtu.be/Fr2i1kVPDnc

Immunohistochemistry Antibody Stains Available

SKIN BIOPSIES FOR IMMUNOFLUORESCENCE - also see DIFL below

Skin biopsies may be for paraffin processing and/or for immunofluorescence only. Submit tissue for immunofluorescence in Michels Transport Medium (MTM) with a separate biopsy in formalin for routine Histology. Please telephone the laboratory on extn 22090 and inform the staff that a specimen for immunoflourescence has been sent.

MTM is available from the laboratory on request.

SMALL BIOPSIES

Immerse immediately in at least a ten-fold volume of 10% formalin in an adequately sizes and tightly sealed container.

DIRECT IMMUNOFLUORESCENCE (DIFL)

Send all specimens either in Michel's Transport Medium OR urgently, fresh on saline soaked gauze.

If sending fresh (from within the ADHB or other DHB's/medical centre's/laboratories) - The specimen MUST be received by the lab no later than 4pm Monday - Friday. DO NOT send fresh specimens over the weekend.

All fresh specimens must be accompanied by an orange request form and the Histology Lab must be notified on extn 22090, before sending.

Specimens for DIFL sent together with tissue for paraffin processing, are placed on hold until requested by the Pathologist reviewing the paraffin block material. Specimens for DIFL only investigations are usually processed the following day after receipt in the lab.

Whether sending fresh or in transport medium and regardless from where the specimen has been sent, please phone the lab and inform them that a specimen for DIFL is on the way. This allows the lab to track the specimen and get in touch with the sender should the specimen not arrive in the lab in a timely fashion

MTM is available from the laboratory on request.

LABELLING

In addition to the requirements of the Company Policy regarding specimen labelling, please include the following information:

Specimen Type

Pertinent Clinical / Operative details

Legible signature and printed name

The Examination of Body Parts and Tissues

A comprehensive explanation is available for all patients, whose body part/tissue may require histological investigation in the booklet "The Examination and Return of Body Parts and Tissues" - CC5074


Turnaround Time:

Turnaround Time Varies

Please note that all TAT's are working days i.e. Monday - Friday and exclude weekends and statutory holidays.

Histology reports

TAT for urgents is 3-5 working days.

TAT for non-urgent is 90% of cases reported in 10 working days. However it should be noted that TAT is governed by the complexity of the specimen and any additional testing may extend the TAT to greater than 10 working days.

Urgent Reports

Results may be available earlier if the clinical situation warrants this, through consultation with the on-call Histopathologist. Clinical staff to whom the results are to be communicated should be specified with locator, mobile and/or extension numbers.

Rapid Paraffin Sections/Slow Mohs

Typically for 'slow Mohs' staged surgical excision of skin tumours requiring margins before reconstruction 2-3 days later. Paraffin sections require overnight processing and provide superior quality sections compared to frozen sections. Specimens need to arrive at LabPlus, Grafton before 4pm to enable accession, dissection and overnight processing. For specimens sent from Greenlane or Waitakere be aware transport can be slow on Friday afternoons and may miss the 4pm cut off. The lab does not process specimens on weekends or public holidays.

For specimens processed overnight, the result can be available the next day, but if immunohistochemistry or levels are required, another day is needed. Immunohistochemistry is often required for melanotic lesions.

  • Notify the laboratory before sending ext 22090

  • Activate the the rapid specimen transport pathway

  • The reconstructing surgeon should ensure they have the result before commencing surgery. If the result is not on RCP, phone the lab ext 22090 and speak to the on call pathologist for a verbal report.

  • Fill in an Orange form, and attach an Urgent sticker. Use the following template.
