Frequently Asked Questions
How many tests does one kit provide?
This kit (SKU 3469) supplies materials for 100 ESR tests, including Westergren pipettes and prefilled citrate vials, priced at $179.10 per kit.
What anticoagulant is used in the citrate vials?
The vials are prefilled with sodium citrate at the standard 3.8% concentration, used to dilute the blood sample in the prescribed Westergren ratio before sedimentation.
What read scale does the system use?
Pipettes follow the standard Westergren 0–200 mm graduated scale, allowing direct sedimentation measurement in millimeters at the one-hour endpoint.
Is the kit sterile?
Components are non-sterile and intended for single-use in vitro diagnostic ESR testing. Each lot is documented for traceability across accredited workflows.
