Laboratory Handling

Transport

Specimens are transported in 10% neutral buffered formalin

Sample Stability

Specimens that are fixed in 10% neutral buffered formalin are stable at room temperature

Synonyms

Iris, Conjunctiva, Thin Flimsy, DMEK, DSAEK, Small Ophthalmic Biopsy

Turnaround Time

15 days

Our reporting timelines are aligned with the RCPA's benchmark for Anatomical Pathology. We aim to provide final Pathologist reports according to the following performance targets: 80% of cases reported within 5 working days, 90% of cases reported within 10 working days. 98% of cases reported within 15 working days. Notes: These timelines apply to routine cases. Complex cases requiring additional investigation may require extended processing times.

Limitations / Interference

The most common errors are preanalytical factors before the specimen reaches the lab:
Patient labelling error
Specimen type not indicated.
Inappropriate fixative.
Sampling error.
Insufficient clinical information.
Inadequate responsible clinician information

Uncertainty of Measurement

Uncertainty of measurement is not applicable to routine histology, as this is a qualitative, interpretative test.
