Accu-Sed Plus ESR Controls

Accu-Sed Plus from ELITech is a quality-control material for erythrocyte sedimentation rate (ESR) testing, giving laboratories a reliable way to verify that their sedimentation systems are reading accurately day after day. Running a validated control alongside patient samples is what turns an ESR result into a defensible one — and that's exactly the assurance this line is built to deliver.

We carry Accu-Sed Plus in two assayed levels: the ELITech Accu-Sed Plus Control, DS-71002 and the ELITech Accu-Sed Plus Control, DS-71003. Stocking both lets a lab bracket its measuring range, confirming instrument performance at more than one point on the scale rather than trusting a single value.

Labs choosing an ESR control typically want to know three things, so here's the short version. The material is assayed, meaning each lot ships with target ranges you compare your results against. It's designed for the sedimentation methods these controls are intended to support, so check compatibility with your specific analyzer or Westergren-based workflow before ordering. And because controls carry lot-specific values and dating, order in a cadence that keeps fresh, in-date product on the bench without overstocking beyond expiration.

Routine use is straightforward: run the control at the interval your QC protocol and accreditation body require — often each day of testing or per new lot and shipment — log the results, and act on any values that fall outside the assigned range before reporting patient data. Consistent QC documentation is frequently what inspectors ask to see first.

Accu-Sed Plus is part of ELITech's broader diagnostics lineup. If you're building out related testing capability, you may also want to review our Accent Plus analyzer supplies.
