Because microalbuminuria is defined as excretion of 30–300 mg of albumin/24 h (20–200 μg/min, or 30–300 μg/mg of creatinine) (20), the protein field result allows identification of microalbuminuria cases in contrast to the classic reading and reporting of the strips, which can detect only albumin concentrations 150–200 mg/L or higher (21)(22). The dashed lines represent the lower limit of detection (− − −) with the 2 SD limits (- - - -). 0 P values <0.05 were considered significant. 0000007901 00000 n Correlation between protein (albumin) results obtained by quantitative test strip analysis (y) and albumin (x; Behring BN II Nephelometer; n = 220). Correlation between RBC counts (x; flow cytometry) and test strip hemoglobin concentration (y) for RBC counts >25 × 106 cells/L (n = 96). Regression equation for urinary WBC counts above the upper reference limit (25 × 106 cells/L; n = 132). Methods: We compared URISYS 2400 (Roche) quantitative reflectance data with data from the UF-100 (Sysmex) and biochemical data for 436 nonpathologic and pathologic urine samples. >> Peele J, Gadsden R, Crews R.

An improved pyrogallol red-molybdate method for determining total urinary protein. 14 0 obj The intensity of the reaction color of the test pad is detected by measuring the percentage of light reflected from the surface of the test pad. When urinary WBC counts were higher than the upper reference limit (25 × 106 cells/L), the following regression equation was obtained: y (%) = 83.7 −15.4 logx (106 cells/L); Spearman r = −0.688; P <0.001. Opis fizičkih i fizičko-hemijskih karakteristika mokraće: izgled, boja, miris, reakcija i specifična težina. It must be noted, however, that the sensitivity (86%) may be inadequate for patients with known diabetes in whom physicians do not want to miss microalbuminuria in their annual testing. Per informazioni e/o chiarimenti rivolgersi a : segreteria U.O. This instrument offers the possibility to obtain reflectance readings. For WBCs, we found a lower limit of detection of 19 × 106 cells/L (CV = 1.2%). Access to the instrument’s raw data theoretically allows a higher analytical sensitivity for several analytes. In conclusion, quantitative urine test strip analysis provides reliable data on WBCs, RBCs, glucose, and albumin. The dashed lines represent the lower limit of detection (− − −) with the 2 SD limits (- - - -). 16 0 obj Does antihypertensive therapy protect the kidney in essential hypertension?. The within- and between-run CVs for protein, leukocyte esterase, hemoglobin, and glucose are summarized in Table 1. (b) In addition, hemoglobin and leukocyte esterase reflectance data are useful for verifying flow cytometric data on RBCs and WBCs. Hence, extremely alkaline urine samples were not present in the samples we investigated. 4 depicts the correlation between both measurement methods and the lower limit of detection of 0.17 mmol/L (CV = 1.3%) with the 2 SD limits. Viene fornito il contenitore chiuso (capacità 3 litri) ed una provetta sottovuoto tappo bianco. Modificato il 18 aprile 2017 .

On the other hand, the quantitative evaluation of test strips may help to eliminate analytical errors in RBC counting attributable to the presence of yeast cells or large amounts of calcium carbonate crystals (11)(15). TAMPONI URETRALI. Particles that cannot be classified in one of the former categories are counted as “other cells”. Ce intelegem din rezultatul examenului de urina? It could be of special interest in patients with undiagnosed diabetes or hypertension in whom microalbuminuria is regarded as an excellent marker for assessing early renal damage (4)(5)(6)(7), particularly because many patients with non-insulin-dependent diabetes mellitus are asymptomatic and their diabetic state remains undiagnosed for years (24).

Screening and management of microalbuminuria in patients with diabetes mellitus: recommendations to the Scientific Advisory Board of the National Kidney Foundation from an ad hoc committee of the Council on Diabetes Mellitus of the National Kidney Foundation. Because of the procedure for applying the urine to the test strips on the URISYS 2400, improper dipping is no longer a problem, nor is confusion about sample identification or urine contamination caused by dipping the strip in the tube, which potentially leads to interferences with chromatographic methods (31). ECLM. Regeniter A, Haenni V, Risch L, Köchli HP, Colombo JP, Frei R. Urine analysis performed by flow cytometry: reference range determination and comparison to morphological findings, dipstick chemistry and bacterial culture results – a multicenter study. Glucose was measured by a hexokinase method standardized against Standard Reference Material 917a and Standard Reference Material 965 (n = 85), and total protein by a pyrogallol red method (17) (n = 129) with Standard Reference Material 917a as a standard and commercially available reagents for both measurement procedures (Roche) on a Modular P system (Roche). The inhibitory effect of urine on the peroxidase-like activity of hemoglobin and on horseradish peroxidase. Title: Modulo Es Urine Unificato The following regression equation was obtained: y (%) = 78.2 −19.4 logx (106 cells/L); Spearman r = −0.680; P <0.001; Fig. On the basis of ROC analysis, diagnostic sensitivity was 86% (95% confidence interval, 78–92%) and specificity was 84% (95% confidence interval, 76–91%) for a reflectance value of 55.6% when the nephelometric assay was used as the comparison method at a cutoff of 30 mg/L (n = 220; 113 positive and 107 negative cases, respectively). o campione delle urine raccolte. <> Multiple regression analysis was used to investigate a model relating leukocyte esterase and hemoglobin field reflectance. Similarly, protein reflectance data and total protein measurements correlated well (Spearman r = −0.921; P <0.001), which is expected as long as the major protein is albumin. 0000000752 00000 n Evaluation of the Sysmex UF-100 automated urinalysis analyzer. The two outer solid lines represent the 95% prediction interval around the regression line. Correlation between glucose measurements (glucose concentration different from 0) by the hexokinase-based method and glucose test strip reading (n = 85). <> 0000007964 00000 n Examenul de urina este un test de diagnostic si ajuta la identificarea substantelor si a materialului celular din urina, asociate cu diferite tulburari metabolice si renale.

Of course, the frequency of erroneous results depends on the proportion of pathologic samples and on the preanalytical handling of samples. Quantitative determination of hemoglobin in urine. Najčešće hemijske analize su analize na proteine, šećer, ketonska tela, urobilinogen, bilirubin i nitrite. We studied 436 freshly collected urine samples submitted to our routine laboratory for diagnostic urinalysis. Agreement between automated flow cytometry and test strip data was evaluated by Spearman rank analysis. This leads to improved elimination of occasional errors in the WBC and RBC counting channels of the flow cytometer (11). Recently, the URISYS 2400 automated urine test strip analyzer (Roche Diagnostics) was introduced. In recent studies, the correlation (r) between UFC WBCs and WBCs by counting chamber was 0.93–0.98, and that of UFC RBCs and RBCs by counting chamber was 0.83–0.89 (10)(25)(26). Two discrepancies (0.9%) were found in which the test strips on both automated strip readers overestimated the urinary albumin concentration by >10-fold. Modulo di prenotazione. Specific gravity (refractometry based) and clarity are measured in a flow cell, and color is rated with a specific algorithm against the blank pad on the test strip.
