Significant Hemolysis Not Required for Thrombosis in PNH

Paroxysmal nocturnal hemoglobinuria (PNH), a rare hematological condition, presents with hemolytic or thrombotic symptoms. Cumulative thrombosis incidence in PNH over an eight to ten-year period is 23% to 30%, 20% of patients have multi-site thrombosis and 10% present with thrombosis. More...

Immunohistochemical Stain Facilitates cHL Diagnosis

Remarkable efforts are underway to exploit classic Hodgkin lymphoma's (cHL) complex interplay of molecular alterations, loss of B-cell programming, and dependency of tumor microenvironment. More...

Clinical ddPCR Diagnostic Test System Gets FDA Clearance

A test designed for monitoring treatment response in chronic myeloid leukemia and is also the first-ever digital polymerase chain reaction (PCR) product to receive US official government approval. More...

Circulating Plasma DNA Potentially Identifies Incipient Tumors

Early cancer diagnosis might improve survival rates. As circulating tumor DNA (ctDNA) carries cancer-specific modifications, it has great potential as a noninvasive biomarker for detection of incipient tumors. More...

Peripheral Blood Flow Cytometry Classifies Pediatric Acute Leukemia

Historically, flow cytometry performed on the bone marrow aspirate (BMFC) has been the standard for the immunophenotypic characterization of acute leukemia. Recent data have demonstrated the high sensitivity and specificity of peripheral blood flow cytometry for the diagnosis of pediatric leukemia. More...

Leukemia Prematurely Ages Bone Marrow Cells

Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cells. More...

Hypersegmented Neutrophils Associated with Reduced Lung Function

Neutrophils are phagocytic innate immune cells, which patrol the blood vessels and become activated in response to inflammatory triggers. Activation results in neutrophil migration to the site of infection, where pathogens can be eliminated by phagocytosis or NETosis. More...
