Mina Adel Nagi on the Future of ESR Testing with HORIBA’s CoRA Technology

”Discover the Future of ESR Testing with Horiba ’s Patented CoRA Technology
For over 100 years, ESR (Erythrocyte Sedimentation Rate) has remained a key lab marker supporting the assessment of inflammation
Yet, the traditional Westergren approach is often manual, time-consuming, and disconnected from routine CBC workflows.
HORIBA’s CoRA (Correlated Rouleaux Analysis) changes the game by integrating ESR directly into automated hematology analyzers (Yumizen H500E and H550E)—turning a century-old test into a modern, streamlined solution.
The real shift: from “sedimentation” to “aggregation”
Instead of waiting for RBCs to sediment for an hour, CoRA focuses on the earliest ESR phase: rouleaux (RBC aggregation) formation, then correlates it to an ESR-equivalent value.
How it works (in 3 steps)
1. Aspiration / Suction
Whole blood is aspirated through an optical pathway; shear forces slightly deform RBCs, changing the optical signal.
2. Relaxation / Release
Aspiration pauses—cells recover their shape and optical behavior shifts again.
3.Agglomeration / Re-formation
RBCs form rouleaux; increasing intercellular spaces allow higher light transmission.
Near-infrared optical signals are analyzed to calculate ESR rapidly and reliably.
Protein effect
Inflammation increases plasma proteins (acute-phase proteins and immunoglobulins), reducing RBC repulsion → enhancing rouleaux formation → increasing ESR.
Why CoRA Matters
Patent-protected innovation: dynamic RBC aggregation analysis correlated to Westergren
Faster workflows: ESR + CBC/Diff in ~60 seconds
Added clinical value: faster inflammation assessment in critical care, infections, autoimmune cases
Space and cost optimization: one platform, fewer steps, fewer instruments
CoRA isn’t just an upgrade—it’s a paradigm shift, bringing a century-old gold standard into the automated era.”
