Starrsed instruments are measuring the Erythrocyte Sedimentation Rate according to the Westergren method. The Westergren method is the gold standard as affirmed by the ICSH in 2017. Using Starrsed instruments means measuring ESR without compromise.

The Starrsed instrument family

Our Starrsed instrument family is unique. Laboratories can benefit from, fully automated, ESR measurements complying to the gold standard Westergren.

The family of Starrsed instruments offers unequalled ESR measurement with the instrument user in mind. Ease of operation and minimal user maintenance, no more than some inspection and occasional replacement of reagents. 

The Starrsed family ensures that the gold standard Westergren is available for each laboratory and every patient.

The Westergren Method

The International Council for Standardization in Hematology (ICSH) is a Non-Governmental Organization that aims to achieve reliable and reproducible results in laboratory analysis in the field of diagnostic hematology.

Over the past decades, the ICSH has reconfirmed that the Westergren method is the gold standard for ESR measurement. ICSH reaffirmed in 2017 that Westergren is standard for ESR measurements

At RRM, we believe that gold standards are the precise language for medical specialists to advance their correct diagnosis and treatment. That’s why we dedicate our efforts to develop gold standards. Applying gold standards, like Westergren, also allows labs to communicate measurements results safely when performed over different sites, like in hub and spoke networks.


Direct connection with Sysmex XN/XR-series

The Interrliner  is designed for integration with the Sysmex XN/XR-series. This makes the continuous production of ESR results very easy.

Starrsed RS

Automatic ESR instrument for medium & large laboratories

The Starrsed RS (rack serie) is designed for medium sized laboratories and allows this laboratories to perform the ESR test according tot the Westergren (gold standard) method. 

Starrsed ST

Automatic ESR instrument for smaller laboratories

Starrsed ST

The Starrsed ST is designed for smaller sized laboratories and allows this laboratories to perform the ESR test according tot the Westergren (gold standard) method. 

Starrsed TL

Integration potential with TLA systems

The Starrsed TL (Track Line) is designed to be integrated in ah Total Laboratory Automation solution.  (TLA) like Inpeco FlexLab, Abbott Accelerator, Siemens Aptio, GLP (Abbott) and more. It provides a Westergren ESR measurement in combination with TLA solutions.

Starrsed Smart Reagent Program

The new Starrsed instruments use only two reagents for ESR measurement: Starrsed DL (diluent) and Starrsed CR (concentrated rinse). The Starrsed DL and Starrsed CR are packaged in easy-to-handle 10L containers. The Starrsed a concentrate and diluted by the instrument. The reagents are placed in dedicated bays with RFID-reading that uploads reagent information into your instrument.

We are in the process of IVDR registration to market the Starrsed instruments as automated analysers for the quantitative in vitro determination of the Erythrocyte Sedimentation Rate (ESR) of human blood samples in conformity with the Westergren standard. Due to regulatory restrictions the statements on this website should not be seen as a promise of regulatory availability.
