Combining diagnostic information provided by urinary flow cytometry and more quantitative test strip analysis therefore offers a theoretical basis for the development of diagnostic expert systems (11)(12).

The imprecision of urinary flow cytometry is far less than that of conventional urinary microscopy, but in some cases urinary flow cytometry reports erroneous results because of analytical interferences (e.g., calcium carbonate crystals falsely increase erythrocyte counts; confusion between yeast cells and erythrocytes). 0000016642 00000 n Mattenheimer H, Adams EC.

Quantitative determination of hemoglobin in urine. 0000017717 00000 n 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). This implies that the test has the potential to offer a screening for microalbuminuria without increased cost, hence coming closer to the “urine test strip of the future” (23).

Correlation between glucose measurements (glucose concentration different from 0) by the hexokinase-based method and glucose test strip reading (n = 85). Because urinalysis test strips are often used for checking urinary flow cytometry data (11), there is a need for a more quantitative evaluation of urinalysis test strips.

In particular, we wanted to compare the reflectance readings of the protein test field with immunochemical microalbumin determinations. PRELIEVI DOMICILIARI. The UF-100 flow cytometer automatically determines the conductivity, so we performed multiple regression analysis on the study population, calculated in a regression model the hemoglobin reflectance vs RBCs and conductivity, and found that the t-value (as expected) for RBCs was −8.442 (P <0.0001). 0000017492 00000 n >> The principle is based on argon laser flow cytometry.

Sacks DB, Bruns DE, Goldstein DE, Maclaren NK, McDonald JM, Parrott M. Guidelines and recommendations for laboratory analysis in the diagnosis and management of diabetes mellitus. 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). 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.

Hemoglobin reflectance (y; %) = 78.2 − 19.4 log(RBC count; 106 cells/L); (Spearman r = −0.680; P <0.001. Test strip measurements had reasonable lower limits of detection for WBC (19 × 106/L). Predicting diabetic nephropathy [Letter]. The reproducibility of (semi)automated readings is at least as good as visual readings (2), but most authors find the analytical, clinical, and labor cost-saving advantages of (semi)automated vs visual reading to be obvious (3). This offers several possibilities: (a) The sensitivity for albumin may allow affordable screening for microalbuminuria, particularly in patients with undiagnosed renal damage.

Evaluation of the Sysmex UF-100 automated urinalysis analyzer. Because RBCs tend to lyse in urine, we investigated the linearity of the hemoglobin test strip pad. 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).

Because microalbuminuria is generally regarded as an excellent marker for assessing early renal damage in common conditions such as diabetes and hypertension (4)(5)(6)(7) and as an early predictor of preeclampsia during pregnancy (8), the availability of highly sensitive test strip readers opens interesting perspectives for assessing this phenomenon.

Dilution was also monitored with a range of specific gravity of 1.005–1.033 and a median result of 1.017. 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. The lower limit of detection (18) was calculated as the mean value − 3 SD for a blank sample. 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. TEST DI MEARES. Data are expressed in an ordinal scale (as “normal”, “negative”, “positive”, or as nominal concentrations) on the reports, but (quantitative) reflectance data can be downloaded to floppy disks. The detection limit of the URISYS 2400 protein assay was 25 mg/L if restricted to albumin alone and total protein was not considered. Modulo di prenotazione. Secrezioni mammarie.

Because microalbuminuria is characterized by large intraindividual variability, an ordinal-scale answer might be misleading. 1. Liquido seminale per citologia. Of all the diagnostically relevant urinary markers, only albumin and transferrin accept protons well, so the potential error of missing Bence Jones proteinuria remains when test strip screening strategies are used in proteinuria (21), although many cases presenting with Bence Jones or tubular proteinuria show microalbuminuria (23).

Higher correlations were observed for biochemical and test strip data comparing protein and albumin (r = −0.825) and glucose data (r = −0.851). The two outer solid lines represent the 95% prediction interval around the regression line. 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). This is stable for 30 days when stored tightly capped at 2–8 °C. 0000007922 00000 n When monitoring our samples, we found a median pH of 6.5 (95% interval, 5–8).
