Description
INTENDED USE
urea/BUN reagent is intended for the in vitro quantitative determination of urea/BUN in serum, plasma and urine on both automated and manual systems.
Liquid ready-to-use reagents
Urea reagent comes in a liquid format which is more convenient, and can also help reduce the risk of errors occurring.
Linearity
When run as recommended, the assay is linear up to 200 mg/dl (33.3 mmol/l).
If result exceeds 200 mg/dl (33.3 mmol/l), specimen should be diluted with ammonia free water and reassayed. Multiply the result by the dilution factor.
It is possible to use 1 ml of diluted R4 (1:5 with distilled water) by this procedure; the assay is linear up to 300 mg/dl (50 mmol/l).
Excellent sensitivity
The sensitivity is defined as the change of analytical response per unit change in analyte concentration at a path length of 1 cm.
When run as recommended the sensitivity of this assay is 0.2 mg/dl (0.033 mmol/l).
Other features:
• Colorometric method
• Liquid ready-to-use reagents
• Stable to expiry when stored at 2-8◦C
