Are unexpected positive dipstick urine bilirubin results clinically significant? A retrospective review.
BACKGROUND Urine-bilirubin measurement is common in urinalysis dipsticks, which are known to yield a high rate of false positive results. We evaluated the usefulness of this test after multiple physicians in our system reported that they do not act on positive dipstick urine bilirubin findings. METHODS We queried past records to determine how many samples with positive urine bilirubin results...
متن کاملUrine Dipstick Analysis
All samples should be midstream and collected in a clean sterile container. Suprapubic aspiration or fresh catheter samples are ideal, but not always practical. The gold standard method of testing is to remove a small volume of urine from the sterile container with a fresh sterile syringe, and then apply the removed urine to the dipstick. In this way, the remainder of the collected sample conte...
متن کاملAre magnetic resonance imaging undetectable prostate tumours clinically significant? Results of histopathological analyses
OBJECTIVE To investigate whether tumours at threshold values for detection on magnetic resonance imaging (MRI) represent clinically significant tumours or not, and therefore the utility of MRI in active surveillance (AS) protocols. PATIENTS AND METHODS A retrospective analysis of a single institution database was performed after Institutional Review Board approval. Between 2010 and 2013, 1633...
متن کاملDipstick analysis for screening of paediatric urine.
The examination of. urine specimens constitutes a major portion of the work of a clinical microbiology laboratory. Although the prevalence of urinary tract infection varies for different patient populations, most urine specimens are culture negative. In this laboratory only 12% of paediatric urines show evidence of urinary tract infection. The availability of a rapid reliable screening test for...
متن کاملDipstick measurements of urine specific gravity
Aim—To evaluate the reliability of dipstick measurements of urine specific gravity (U-SG). Methods—Fresh urine specimens were tested for urine pH and osmolality (U-pH, U-Osm) by a pH meter and an osmometer, and for U-SG by three diVerent methods (refractometry, automatic readout of a dipstick (Clinitek-50), and (visual) change of colour of the dipstick). Results—The correlations between the vis...
