Flow Cytometric Immunophenotyping Assessed for Classic Hodgkin Lymphoma

The diagnosis of classic Hodgkin lymphoma (CHL) requires morphologic and immunophenotypic identification of neoplastic Hodgkin and Reed-Sternberg cells (collectively referred to as HRS cells) intermixed with a background of reactive lymphocytes, histiocytes, plasma cells, and eosinophils. More...

Biomarker Panel for Risk of Early Respiratory Failure Following Hematopoietic Cell Transplantation

Allogeneic hematopoietic cell transplantation (HCT) is a life-saving therapy used for malignant and nonmalignant diseases. However, post-HCT pulmonary complications continue to be a significant problem. When severe, pulmonary complications can result in respiratory failure (RF), affecting 10% to 23% of patients. More...

Serum Extracellular Vesicle Arginase 1 Measured In T2DM

Serum extracellular vesicle (EV)-derived arginase 1 (ARG 1) plays a critical role in diabetes-associated endothelial dysfunction. This study was performed to determine the levels of serum EV-derived ARG 1 in T2DM and non-T2DM participants and to examine the association of serum EV-derived ARG 1 with T2DM incidence. More...

Enzyme Immunoassays Developed for Serodiagnosis of Human Leptospirosis

The laborious microscopic agglutination test (MAT) is the gold standard serologic test for laboratory diagnosis of leptospirosis. We developed EIA based serologic assays using recombinant proteins (rLigA, rLigB, rLipL32) and whole-cell extracts from eight Leptospira serovars as antigen and assessed the diagnostic performance of the new assay. More...

Diagnostic Biomarker Predicts Risk of Opisthorchiasis Cholangiocarcinoma

Opisthorchiasis is caused by an infection with fish-borne liver flukes of the genus Opisthorchis. Opisthorchiasis frequently leads to chronic inflammation in the biliary tract and is classified as a group 1 biological carcinogen by the International Agency for Research on Cancer: a definitive risk for cholangiocarcinoma (CCA).

Different Assay Evaluated for Thyroglobulin and Thyroglobulin Antibodies

International guidelines recommend fixed cut-off values for thyroglobulin (Tg). These cut-offs do not take potential assay differences into account. This study aimed to evaluate if different assays for Tg and Tg antibodies (TgAb) affect management guidance for differentiated thyroid cancer (DTC) patients. More...

Immunohistochemistry Evaluated for Tissue-Invasive Cytomegalovirus in Gastrointestinal Mucosal Biopsies

Cytomegalovirus (CMV) immunohistochemistry (IHC) is the most widely used method to diagnose CMV infection/reactivation in tissues in a pathology laboratory. More...
