Performance of Swelab Lumi hematology system

Performance comparison of Swelab Lumi hematology system with a reference system intended for use in large hospital laboratories

Hematology analyses are routinely performed both by large clinical hospital laboratories on fully automated, high-throughput analyzers as well as by smaller physician’s office laboratories on stand-alone analyzers. As clinical laboratory tests form the basis for patient diagnosis, analyzer accuracy and precision are equality important independent of sample scale or clinical setting.

Swelab Lumi – reliability when it counts

Swelab Lumi is a hematology system intended for the smaller laboratory (Fig 1). The analyzer provides information on 29 parameters for the CBC, including red blood cells (RBC) and platelets (PLT), hemoglobin (HGB), as well as a 5-part differential count of the WBCs.

Swelab Lumi employs well-proven measurement technologies. The analyzer uses impedance for RBC and PLT counts, while the WBC differential is conducted by laser-based flow cytometry. HGB is determined spectrophotometrically.

Fig 1. Swelab Lumi is a 5-part hematology analyzer intended for the cost-minded clinical laboratory. The user-friendly design makes system operations easy. Robust software and hardware components ensure a reliable system performance. With its small footprint, Swelab Lumi is well suited for the typical physician office laboratory.

Swelab Lumi provides comparable performance to reference system

Dr. Ravindra Patwadkar and coworkers at the Dr. Hedgewar Hospital, Aurangabad, Maharashtra, India conducted a study to compare the performance of Swelab Lumi with a reference system intended for the larger hospital laboratory (Fig 2).

“More than 200 live samples with various value ranges were evaluated simultaneously in the test instrument Medonic M51 and reference instrument Beckman Coulter DxH 800 in the month of August 2018”, Dr Patwadkar explains. “The generated data shows that analysis results obtained with the Medonic M51 5-part hematology system agrees well with those obtained with the reference system.­The demonstrated performance of Medonic M51 in comparison with the reference system indicates the suitability of Medonic M51 for use in routine hematology analysis.”

Passing-Bablok regression graphs are shown for (A) WBC, (B) RBC, (C) HGB, (D) MCV, (E) HCT, (F) RDW%, (G) PLT, and (H) MPV. In regression plots, the gray line is the line of identity (x = y) and the red line is the line of best fit.
