Technical Specifications Albumin 201 system
Sample material: Urine. The analysis can be performed with spot urine, preferably first morning urine, as well as urine collected overnight or during 24 hours.
Measurement range: 7-150 mg/L.
Results: in about 90 seconds.
Sample volume: 18 µL.
Weight: 350 g (0.77 pounds).
Power: AC Adapter.
Power: AC Adapter.
Operating temperature: 15-30 °C (59-86 °F).
Interface: Printer and PC.
Quality control: Built-in "selftest" and liquid controls.
Calibration: The analyzer is factory calibrated against a turbidimetric method traceable to CRM 470 and needs no further calibration.
Storage for HemoCue® Albumin 201 Analyzer: The analyzer can be stored at temperature 0-50 °C (32-122 °F).
Storage for individual packaged HemoCue® Urine Albumin Microcuvettes: Store HemoCue® Urine Albumin Microcuvettes in a refrigerator at 2-8 °C (35-46 °F). Do not store the microcuvettes in the freezer. Allowed to reach room temperature before use. The individually packaged cuvettes can be stored at room temperature for up to 3 days.
Method: A specific rabbit anti-human albumin antibody (polyclonal) forms an agglutinate with human albumin in the sample. The agglutination is enhanced by polymers. The turbidity of the agglutinates, once formed, is measured photometrically at 610 nm. Microalbuminuria in diabetes mellitus: review and recommendations for the measurement of albumin in urine.

Principle: When the immunochemical reaction is completed the turbidity is measured photometrically at 610 nm. The albumin concentration is proportional to the turbidity and the result is shown on the display in mg/L.
