- Immediately after the biopsy is obtained:
- Place biopsy cores in each of the three specimen bottles.
- If only a single core is obtained, and if IF and/or EM will be essential for establishing the diagnosis, divide in three parts with clean, sharp blade as indicated in the diagram.
- If wedge biopsy, cut in 1-2 mm blocks. Handle all pieces carefully. Avoid crushing.
- Place pieces in containers, as indicated by diagram, as quickly as possible. Priority should be given to: a) light microscopy, b) immunofluorescence, c) electron microscopy.
- Deliver as soon as possible.
- Do not freeze the specimens or ship on dry ice.
Please do not ship for weekend or holiday delivery without prior notification.
