The request for a urine status in the laboratory routine mostly concerns incoming orders within the scope of health check-ups or screening tests, or problems relating to an existing urinary tract infection or possible haematuria. After urine flow cytometry had made its arrival in urinalysis more than 10 years ago, Sysmex today offers the fluorescence flow cytometers UF-1000i and UF-500i with the advantageous semi-conductor laser technology for the analysis of urine.
Various possibilities for screening have become established to obtain information on a urinary tract infection as quickly and as reliably as possible, and also to reduce the number of negative cultures. The fluorescence flow cytometry technology makes it possible to report the majority of negative samples immediately to the doctor and to thus save this part of the culture workload.
The term ‘NRBC’ – ‘nucleated red blood cells’ – refers to precursor cells of the red blood cell lineage which still contain a nucleus. In healthy adults and older children, NRBC can only be found in blood-building bone marrow where they mature. Their appearance in peripheral blood points to extramedullary erythropoiesis or disruption of the blood - bone marrow barrier. Both possible scenarios can only be found in the course of a severe disease.
Direct detection of blood doping is relatively time-consuming and cost intensive. Some of the banned substances, such as recombinant human erythropoietin (rhEPO), can hardly be distinguished from natural, endogenous hormones. This SEED describes how it is nevertheless possible to indirectly detect EPO-like doping with a modern haematology analyser like the XN-Series and reticulocyte parameters. The World Anti-Doping Agency (WADA) has played a leading role in the development of the Athlete Biological Passport for monitoring blood parameters such as RET#, RET%, HGB or HCT to ensure fairness among athletes.
The capability to count blood cells beyond the classical 5-part differential with high reliability is a challenge for modern haematology analysers. Sysmex offers the immature granulocyte count (IG) optionally on the XE-series and XT-series analysers. It is a standard diagnostic parameter on the XT-4000i, the XE-5000 and on the new XN-series as well.
Thrombocytopenia occurs in 30% of all neonates admitted to intensive care. Young, immature platelets containing RNA, measured as “immature platelet fraction” (IPF) on Sysmex analyzers, can help to assess platelet production. Thus, they allow conclusions on both the etiology and the likely course of thrombocytopenia in neonates.
