Laboratory Information

Test Name

Fluid: Pleural, Pericardial ( Microbiology )

Specimen Collection

Pre Testing Requirements

For pH analysis, a separate aliquot of sample must be received in a syringe to ensure anaerobiasis.

Adult Specimen

Specimen Collection: Aseptically aspirated fluid. Specimens should be collected into a sterile container. Anticoagulant may be inhibitory to some organisms, therefore is not recommended for specimens requiring culture. Collection of a separate aliquot with anticoagulant is advised for microscopy. Inoculation of blood culture bottles is advised where enough volume of fluid is available.

Department

Microbiology

Test Availability

Laboratory Turnaround Time

Microscopy 2 hours / Culture 5 days

Method

Microscopy (Cell count / differential) & culture. Biochemistry tests as requested (COBAS CCE analyser)

Additional Information

Pleural fluids suggestive of empyema or lung abscess will be cultured for anaerobes. Pericardial fluids that are visibly blood stained will be tested for haemoglobin and protein estimations to ensure the specimen is pericardial fluid and not blood.
Processing available urgently as call out via Clinician request  2400 - 0800 hrs.
