All potential pathogens (e.g. Staphylococcus aureus or Group A Streptococcus) will be reported along with antimicrobial sensitivities. Certain organism groups, e.g. coliforms such as Escherichia coli, will only be reported if growth is pure or heavy. Uro-genital tract Urine The preferred urine specimens are clean catch (young children) or mid-stream (older children): these specimens are less likely to be contaminated by skin organisms than bag specimens. The laboratory processes the specimens in a quantitative manner, to enable significant growth to be detected. Urine culture results are reported as summarised in the table below. See also section 4.2.5, regarding suspected melioidosis.
