When positive nitrites were combined with symptoms of a UTI in a urogynecologic population undergoing cystometry, the sensitivity of a nitrite-positive test to detect a UTI increased from 40 to 89 ...
- culture (UTI if ≥10 4 bacteria/mL) p(UTI) = 71% (55/78) Jellheden B (23) 1996: systematic register of clinical findings from all patients - 819 women with signs and symptoms suggesting UTI ...
A total of 1, 212 articles were retrieved via an automated search (1, 059 from the MEDLINE database, 242 from the EMBASE database, 89 found in both databases). We excluded studies of urinary tract ...
Nitrites or leukocytes in the dipstick test are the only findings that clearly favored a diagnosis of UTI. Conclusions Clinical findings do not aid in the diagnosis of UTI among women who present ...
Urinary leukocyte esterase and nitrites were present in 83 and 33% of tested urine samples, respectively. Blood cultures were obtained from 353 infants (91%), of which 26 (7.4%) were positive.
For example, UTI test kits may produce false-negative results because not all UTI-causing organisms produce nitrites and because LE is a polymorphic enzyme produced by white blood cells and may ...
The presence of nitrites and/or leukocyte esterase in urine has good overall sensitivity (46–100%) and specificity (42–98%) for culture-proven urinary tract infection.
0. A case of false-positive alcohol toxicology tests believed to be linked to treatment with sodium-glucose cotransporter 2 (SGLT2) inhibitors raises concern that the widely used diabetes drugs ...
Reports of false-positive UDS results were found for 25 (21.5%) of 116 formulary medications. The potential for false-positive UDS results was identified for the following medication classes on ...
