The Sysmex UF-100 is a urinary flow cytometer-based walkaway instrument that performs automated microscopic analysis. In our study correlating test strip data with urinary flow results, r was −0.69 between the flow cytometric WBC count and the leukocyte esterase reaction, although the presence of esterase inhibitors in urine and severe proteinuria might negatively affect test results for leukocyte esterase (1)(27). 0000000752 00000 n The turnaround time was short enough (2–4 h) not to affect the readings: time intervals can influence results of automated test strip analysis, especially leukocyte and erythrocyte ratings (19).

We studied 436 freshly collected urine samples submitted to our routine laboratory for diagnostic urinalysis. 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). 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 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).

Access to the instrument’s raw data theoretically allows a higher analytical sensitivity for several analytes. 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. 0000000868 00000 n Urine test strip analysis was performed with the automated URISYS 2400. For WBCs, we found a lower limit of detection of 19 × 106 cells/L (CV = 1.2%).

As shown by our multiple regression model and dilution experiments, the hemoglobin field reflectance test is not influenced by dilution effects. We also wanted to explore the possibilities of combining the two novel methods, particularly in the analysis of erythrocytes, leukocytes, and glucose, which are of major clinical importance.

Guidelines and recommendations for laboratory analysis in the diagnosis and management of diabetes mellitus. 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. Nissell H, Kublickas M, Lunnell NO, Petterson E. Renal function in gravidas with chronic hypertension with and without superimposed preeclampsia. 0000017620 00000 n Westgard JO. 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).

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. (b) In addition, hemoglobin and leukocyte esterase reflectance data are useful for verifying flow cytometric data on RBCs and WBCs. 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). This offers several possibilities: (a) The sensitivity for albumin may allow affordable screening for microalbuminuria, particularly in patients with undiagnosed renal damage. %PDF-1.4 Urine per esami di citologia urinaria raccolte Castelfranco Emilia. >> 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).

The higher the analyte, the higher the color intensity and, thus, the lower the reflectance. 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). 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.
