what is the principle of reflectance photometry?
the increased concentration of a substance leads to increased color intensity and decreased light reflected
increased concentration is directly proportional to color intensity and inversely proportional to light reflection
what are the benefits of automation?
improved result reproducibility, increased productivity, and standardization for reporting results
which types of flagged particles must be confirmed by manual microscopy?
pathological casts, crystals, small round cells (renal tubular epithelial cells (RTE’s) or transitional epithelial cells), sperm, mucus, and yeastlike cells
what situations require a manual blood count?
hemacytometer count, and body fluids with low cell counts or malignant cells
what method is used to measure specific gravity in automated urinalysis?
refractometry
which two technologies are used for urine sediment analysis?
flow cytometry and digital imaging
