Teco Diagnostics is proud to introduce our complete line of Urinalysis products. From our world renowned Urine Reagent Strips (URS) to our semi-automated Urine Strip Readers.
Method:
Color Indicator
Testing Procedure:
Manual
Storage Temperature:
15‐30°C
Expected Values/Sensitivity:
Glucose: Concentrations as little 0.1g/dL may be significantly abnormal if found
consistently (100mg/dL sensitivity)
Specific Gravity: Random urine varies in specific gravity from 1.003‐1.040+ (correlates
within 0.005 with values obtained with the refractive index method)
pH: Newborn: 5.0‐7.0; Thereafter: 4.5‐8.0 ; Average: 6.0 (quantitative differentiation of
values to one unit)
Protein: 1‐14mg/dL may be excreted by the normal kidney (15mg/dL sensitivity)
Limitations of Procedure:
Glucose: Moderate amounts of ketone bodies (40mg/dL or greater) may decrease color
development in urine containing small amounts of glucose (75‐125mg/dL). However,
such concentration of ketone simultaneously with such glucose concentration is
metabolically improbable in screening. The reactivity of the glucose test decreases as the
specific gravity and/or ascorbic acid of the urine increases. Reactivity may also vary with
temperature.
Specific Gravity: The chemical nature of the specific gravity test may cause slightly
different results from those obtained with the specific gravity methods when elevated
amounts of certain urine constituents are present. Highly buffered alkaline urine may
cause low readings relative to other methods. Elevated specific gravity readings may be
obtained in the presence of moderate quantities (100‐750mg/dL) of protein.
