There are 3 body cavities which under normal conditions contain a small amount of fluid
Accumulation of fluid in these serous cavities is a reflection of local or systemic disease and examination of the cells in the fluid can be of great value in establishing the underlying disease process.
Serous fluids may be either transudates or exudates.
Exudates appear due to an active accumulation of fluid within the body cavities, associated with damaged capillary walls.
There are two main causes of exudates:
When sending a serous effusion (including peritoneal, ascites, pleural and pericardial samples) to Cytology:
The request should state:
All Trust specimens must be requested on Epic and be labelled with an Epic label. GPOCS requests must be labelled with a GPOCS label. All other samples must have a request form.
HIGH RISK SPECIMENS: Requests must indicate if a specimen is high risk. Please indicate details of the risk, eg: TB, blood-borne virus, etc.
URGENT SPECIMENS: Please label urgent specimens clearly; an explanation as to why the specimen is urgent is helpful. On receipt, laboratory staff will notify the pathologist who will report the specimen as soon as possible.
The Laboratory aims to comply with The Royal College of Pathologists Key Performance Indicator (KPI 6.4) for Cellular Pathology reporting turnaround times with 90% of all cases reported within 10 calendar days.
