| Collection & Request Instructions: | As soon as is practical after excision fix tissue specimens in glutaraldehyde fixative. SA Patholgy's standard fixative is 2.5% glutaraldehyde in 0.1M sodium cacodylate buffer. Other buffering agents such as phosphate are also acceptable.
The specimen can be collected into formalin and transferred to glutaraldehyde in the laboratory. If glutaraldehyde is unavailable the tissue can be fixed with buffered formalin, but the tissue morphology and diagnosis may be compromised.

| Processing Instructions: | Allow the specimen to fix for 24 hours in glutaraldehyde fixative before transport to SA Pathology. If the specimen is received in formalin transfer to EM fixative as soon as possible.

| External Transport Instructions: | The specimen cannot be transported to SA Pathology in glutaraldehyde fixative.
Glutaraldehyde and cacodylate buffer are both dangerous goods.
Fix the tissue specimen overnight and then wash, transport in phosphate buffer only. |
