Within 12 hours unless refrigerated | | Turn around time for final test | 24 hours for negative samples 3 working days for positive samples (*Resistant organisms which require further testing may take longer). | | Uncertainty of testing | Please note, a proportion of older people in long term care will have asymptomatic bacteruria (40% women and 15% men). Diagnosis of urinary tract infections in these individuals MUST be based on clinical presentation with a urine sample ONLY being sent for confirmation and to investigate which antibiotic will be appropriate.
| | Reference range | This is a semi-quantitative test and all counts of 107/CFU /L are counted as significant.These samples will be processed with regards to identification and antimicrobial sensitivity testing | | Appropriate testing /re-testing interval | Only send repeat post treatment specimens, if the patient becomes symptomatic again. If it is clinically important to ensure that eradication has occurred in patients such as pregnant women, children with ureteric reflux or patients with recurrent infections where relapse is thought to have occurred, then repeat specimens should not be sent before 3-4 weeks after the completion of treatment.
