Most routine Clinical Biochemistry blood tests can be undertaken on 6 ml. sample collected into a Vacutainer SST tube (yellow top). Common exceptions are on shown on wall chart (please click).
Glucose analysis may be undertaken on unpreserved samples, but the result may be lowered if the sample is not analysed within 4 hours, or if glucose is being metabolised rapidly (e.g. in septicaemia or some forms of leukaemia). Under these circumstances, a 2ml samples in a fluoride oxalate tube (grey top) is required
Requests for alcohol are not routinely available without prior discussion with the laboratory. A 2ml samples in a fluoride oxalate tube (grey top) is required.
Paediatric samples for most Clinical Biochemistry tests may be collected into a 2 ml heparinised micro tube (orange cap). 2 ml fluoride oxalate micro tubes are also available for glucose.
All blood gas samples are analysed ‘Point of Care’ and require an arterial sample taken into an heparinised syringe.
Plain 25ml containers (white top) are available from supplies distribution for random, MSU and EMU samples. 24 hour urine containers with any necessary preservative, are available from Pathology reception. Information on urine collection and preservatives required is available.
Plain 25ml faecal containers (blue top) are available from supplies distribution.
