Evaluation of Swelab Lumi hematology system

Typically, hematology analyses are performed in large clinical core laboratories. However, there are circumstances, under which near-patient monitoring of blood cell counts can be essential. Independent of clinical setup, accuracy and precision of the clinical analyses are of equal importance.

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 white blood cell (WBC), red blood cell (RBC) and platelet (PLT) counts 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. Hemoglobin (HGB) is determined spectrophotometrically.

Swelab Lumi 5-part hematology analyzer

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.

In agreement reference system

Dr. S.P. Ganesan and coworkers at the Hitech Diagnostic Centre (HDC) in Chennai, India conducted a study to compare the performance of Swelab Lumi with a reference system intended for the larger hospital laboratory (Fig 2).

”Swelab Lumi is an entry-level hematology system intended for the smaller laboratory. The work conducted in collaboration between Boule Diagnostics and Hitech Diagnostic Centre (HDC) in Chennai, India compares the performance of Swelab Lumi with the XN-1000 reference hematology system (Sysmex Corp.) intended for the large clinical laboratory”, Dr. Ganesan explains. “The results show that Swelab Lumi is in good agreement with the reference system. The analyzers provide similar conditions for patient decisions. Swelab Lumi generated analytical data close to microscopic examination and is a good option for the smaller clinical and hospital laboratories.”

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.
