A short introduction to the concepts of metrological traceability and measurement uncertainty is given in the article for readers who are not familiar with them. It also includes a short description of the steps needed to evaluate uncertainty. The article further explains how traceability is assured for the Sysmex haematology calibrators and describes how the uncertainty of these calibrators was evaluated.
Synovial fluid is a viscous liquid found in the cavities of synovial joints. Several articular diseases are characterised by fluid accumulation in joints, so that arthrocentesis and morphological analysis are essential tools for differentiating a non-inflammatory arthropathy from an inflammatory arthropathy or an infectious disease. Cell count and differentiation are important diagnostic aspects in such patients. This first SEED article about synovial fluid summarises the typical characteristics and recommends procedures for specimen collection and handling.
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.
