Mid-stream urine (MSU)
Microscopy is performed on a fully automated cytometry analyser. Manual microscopy is only performed as an alternative if the specimen is not suitable for the automated method. The cytometry or microscopy is used as a screening test to screen out all negative urine samples in the majority of samples.
Urine samples with positive cytometry or microscopy will be cultured for isolation, identification and susceptibility of likely pathogens. Samples from specific groups will have automatic culture irrespective of cytometry or microscopy result (such as children, transplant, renal, oncology, haematology and obstetric patients).
Not all susceptibility test results are routinely released and additional advice can be obtained from the consultant microbiologist if required.
Any culture result must be interpreted in context of the clinical picture.
Where possible please send separate samples for individual tests as samples may be processed in different departments such as cytology or virology.
Please indicate where a high risk pathogen may be implicated (such as Salmonella typhi)
Start to urinate and collect a sample of urine "mid-stream" in a sterile screw-top container.
