Frequently Asked Questions
How many tests does one unit provide?
Each unit contains 10 boxes of 100 tests, for a total of 1000 ESR determinations. Pipettes and citrate vials are supplied together in matched quantities.
Does this system follow the Westergren method?
Yes. The pipettes use the standardized 200 mm Westergren scale, and the citrate vials provide the correct sodium citrate dilution ratio for reproducible sedimentation rate measurement.
Is the sample diluted automatically?
The citrate vials are pre-filled with sodium citrate diluent. After adding the specified whole-blood volume, the system delivers the proper dilution before the pipette is filled and read.
Are lot numbers provided for traceability?
Yes. Boxes and unit cartons carry lot numbers so accredited labs can document traceability in compliance with CAP, CLIA, and ISO 15189 records.
