Electron Microscopy

Electron Microscopy

Native and transplant kidney biopsies:

The Electron Microscopy Unit provides a service for the West-London Renal and Transplant Unit based at Hammersmith Hospital. The results of the ultrastructural examination of a tissue sample by Dr Linda Moran and Dr Heather Brooks supplement the light microscopy (including special stains and immunocytochemistry) to guide the clinical team to adopt the most appropriate treatment pathway for each individual patient.

The diagnostic renal service is co-ordinated by the Consultant Renal Histopathologists Dr Candice Roufosse (candice.roufosse@nhs.net, Subspecialty Lead), Dr Andrew Smith (andrew.smith17@nhs.net) and Dr Naomi Simmonds (n.simmonds@nhs.net).

The EM Unit provides an equivalent external Ultrastructural Renal Diagnostic and Neuropathology Service to other Hospital Trusts.

Other samples examined within the EM Unit include: skin and duodenum.

See Notes

• Renal core biopsies – a core biopsy needs to be sent to the EM Unit (Histopathology Department) in an adequately sized container, fully labelled with patient demographics.  All core biopsies require sufficient 3% glutaraldehyde in 0.1M sodium cacodylate buffer to cover the specimen (EM Fixative is available in advance on request).
• Other surgical specimens – small tissue samples (no greater than 1 mm in one dimension) need to be sent to the EM Unit (Histopathology Department) in an adequately sized container, fully labelled with patient demographics.  All biopsies require sufficient 3% glutaraldehyde in 0.1M sodium cacodylate buffer to cover the specimen (EM fixative is available in advance on request).
• Reprocessing of wax blocks – wax blocks for ultrastructural examination should be marked with the sending laboratory’s accession number. Ensure the blocks are wrapped in protective material/container to prevent damage in transit.

At times, it may be necessary to refer work to other laboratories or consultants. This requirement is assessed on a case-by-case basis.
