ESR TUBE
In stock
In veterinary medicine, an ESR (Erythrocyte Sedimentation Rate) tube is used to measure the speed at which red blood cells settle in anticoagulated blood. It is primarily a screening tool to detect systemic inflammation caused by infections, urinary or orthopedic disorders, and chronic conditions.

Specs & features.
The ESR test relies on a basic biological phenomenon: when inflammation occurs, the liver releases acute-phase proteins (like fibrinogen) into the bloodstream. These proteins reduce the natural repulsive charge of red blood cells, causing them to clump together into coin-like stacks called rouleaux. Because they are heavier, these clumps settle to the bottom of the tube more rapidly.

- Anticoagulant: Standard ESR tubes contain 3.2% or 3.8% buffered sodium citrate. (Modern automated setups, however, can run the test directly on whole blood collected in standard K3-EDTA Tubes).
- Design & Materials: They are narrow-diameter, pre-calibrated glass or high-grade PET plastic tubes designed to keep the blood column perfectly vertical during the reading phase.
- Color Coding: Internationally, ESR Blood Collection Tubes are typically identified by their black caps, though some European or automated standards use purple.
