Conversely, false-negative results can be due to the presence of large amounts of reducing agents such as ascorbic acid or urine with high specific gravity, in which case the dipstick test is less sensitive. Because of the sensitive nature of the urine dipstick test, it is unwise to ...
The degradation products formed under those circumstances (including biliverdin) do not react with the test, causing false-negative test results. To avoid this, urine should be evaluated within 30 minutes of collection or be refrigerated, kept dark, and (for other tests) brought to room ...

Having another neuropsychiatric disorder, chronic diseases such as diabetes, hypertension, etc., abnormal urine test results, complaints related to the urinary system, and using any medication were determined as exclu- sion criteria. In addition, the presence of leucocytes, protein, blood, glucose, ...
A further dataset (Set 2) of 1,170 samples was investigated to compare urinary results with blood, where total weight arsenic was detected in parallel in EDTA whole blood and urine. The samples of Set 2 were obtained and analyzed by IMD between April 2014 and March 2024. The original 1,...
However, the fact that a similar percentage of controls are also LAM-ELISA positive suggests that the positive results in patients with solely NTM infection are not really attributable to cross-reactivity of the test. The sensitivity of the LAM-ELISA is noticeably higher in HIV-infected patients ...
Corrected urine Se concentrations explained more of the between-cluster variation in plasma Se concentration than uncorrected data. These results provide new evidence that urine may be used in the surveillance of Se status at the population level in some groups. This could be a cost-effective ...
To confirm our assumption, comparisons with dependent analyses (paired t-test, Wilcoxon signed-rank test and linear mixed models) yielded highly comparable results (data presented in the supplementary information). Furthermore, consideration of age in linear models was justified by potential residual ...
i.e. 3 months after SCI. An early application of SNM may at least partly prevent the formation or emergence of pathological reflex circuits in the spinal cord below the lesion during the spinal shock phase that otherwise results in NDO. Also, detrusor inhibitory effects via the sympathetic hypo...
The Mann–Whitney U test was used to determine statistically significant differences between the production line and back office groups for the results from each element (significance level p < 0.05). The Spearman's rank correlation test was used to indicate the correlations between two sets ...
