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.
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.
Thrombocytopenia is a disorder in which there is an abnormally low amount of platelets. It can be life threatening and its detection and precise count is extremely important. The immature platelet fraction (IPF parameter) measures young, reticulated platelets in peripheral Blood, revealing if the bone marrow is producing or not.
Myelodysplastic syndromes (MDS) often go unnoticed when only a complete blood count is performed on the patient. Sysmex X-Class analysers can measure the granularity of leukocytes which is often reduced in MDS. NEUT-X, the measure of neutrophil granularity, is an excellent tool to filter samples suspected of MDS in anaemic patients.
By combining the WDF and WPC channels both the sensitivity and specificity for detecting reactive and malignant cells is optimised. The measurement technology of XN-Series analysers detects the white blood cell functionality and the novel ‘Extended Inflammation Parameters’ let you quantify activated lymphocytes and neutrophils, and the results can be applied once a malignancy has been excluded.
