Automation Flashcards
uses laser-based flow cytometry that measures forward light scatter, side scatter, fluorescence staining characteristics, and adaptive cluster analysis to identify stained urine sediment particles
Sysmex UF-1000i
Major variable in urinalysis testing
conscientiousness of the laboratory personnel in their timing and interpretations of the color reactions
Ultimate goal of urinalysis automation
improve reproducibility and color discrimination while increasing productivity and standardization for reporting urinalysis results
Correct color readings depend on the accuracy of the timing.
A. True
B. False
A. True
Term for spectrophotometric measurement of light reflection
Reflectance photometry
Principle of reflectance photometry
Uses the principle that light reflection from the test pads decreases in proportion to the intensity of color produced by the concentration of the test substance
Designed for a high-volume urinalysis laboratory with user walk-away capability.
Fully automated instruments
Tests for the chemical components of urine. The instruments read and interpret the reagent strip results consistently, thereby standardizing the interpretation of reagent strip results and eliminating personnel color bias and timing discrepancies
Semi-automated urine analyzers
Not easily standardized because of the high variation among operators even in the same institution. Not cost effective due to labor and time required to process and analyze specimen.
Manual microscopy
provide efficient standardized results in less than 1 minute, markedly improving turnaround times.
Automated urine cell analyzers
the newest generation hematology analyzer that includes a dedicated body fluid mode.
Sysmex XE-5000
Traditionally used in body fluid cell counts and differentials
Neubauer hemocytometer
provide a rapid automated diagnostic test for fetal lung maturity by counting lamellar bodies in amniotic fluid.
