Pre-testing Requirements

Specimen must be submitted in Cytolyt preservative, please use pre filled conical tubes with cytolyt. Please ring MMH cytology at 09 2760000 extn. 59495 for these tubes
If flow cytometry is required, separate sample in IMDM or saline must be submitted
If microbiology test is required, a separate sterile specimen (either NEAT or in saline) must be submitted to Microbiology

Additional Specimen Information

Place sample in 50 ml conical tubes with cytolyt preservative

FINE NEEDLE ASPIRATIONS (FNA)
The yield of diagnostic information is directly proportional to adequate aspiration technique and preparation of material.
Material aspirated for Cytology assessment only should be rinsed into Cytolyt solution (provided by the laboratory). If an infectious aetiology / lymphoproliferative disorder is a possible alternated diagnosis, please provide additional aspirated material for microbiological culture / flow cytometry (and submitted in appropriate medium). Correct and relevant clinical information must be provided and accurate labelling of specimens intended for cytology and microbiology is required. All material should be sent to the laboratory as soon as possible.

RAPID ON-SITE EVALUATION (ROSE) FOR IMAGED GUIDED FNA
When a Cytopathologist is required to attend or perform a fine needle aspirate (FNA) a provisional opinion will be given regarding specimen adequacy followed by a formal report after re-examination of all the prepared material in the laboratory.
Specially trained cytoscientists may also attend ROSE for image guided FNA procedures.
