Blood Tests Offer Early Indicator of Severe COVID-19

For most patients, COVID-19 manifests as an upper respiratory tract infection that is self-limited. However, the progression of COVID-19 in a large subset of patients to respiratory distress, multiorgan failure, and death has resulted in an enormous global impact. More...

Rh Alloimmunization Explored in Chronically Transfused Thalassemia Patients

Chronic life-long transfusions are often required for patients with severe thalassemia to provide normal red blood cells and to suppress the patients’ own ineffective erythropoiesis. Cumulative exposure increases the risk for red cell alloimmunization and subsequent delayed hemolytic transfusion reactions (DHTRs). More...

Next Generation Sequencing Finds More Gene Mutations for Leukemia

Myeloid malignancies are characterized by uncontrolled proliferation and/or defects in differentiation of abnormal myeloid progenitor cells. Myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPNs) are often thought to be precursors to a higher grade myeloid malignancies, namely acute myeloid leukemia (AML). More...

Biomarker Predicts Pancreatic Cancer Patients’ Response to CD40 Immunotherapy

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and currently the third leading cause of cancer deaths in the USA. Despite the fact that it only accounts for about 3% of new cancer cases, it is responsible for more than 7% of all cancer deaths, and only10% of patients survive five years with the disease. More...

Automated Leucocyte VCS Parameters Evaluated for Pathogenic Infections

 Malaria and dengue are highly endemic in most parts of India. Mangalore, a city in coastal Karnataka, India, has high prevalence of both these vector‐borne infections with extensive range of clinical presentations. The outbreak of these infections is common during and after the rainy season. More...

TFP Inhibitor Levels Elevated in Bleeding Tendency Patients

Mild to moderate bleeding disorders (MBDs) are characterized by symptoms such as epistaxis, easy bruising, or menorrhagia, but bleeding can also be severe under certain circumstances such as hemorrhage after surgery or birth. More...

RDW Levels Associated with Adverse Outcomes in COVID-19 Patients

The red cell distribution width (RDW) blood test measures the amount of red blood cell variation in volume and size. RDW is not used as an isolated parameter when interpreting a complete blood count (CBC); instead, it provides shades of meaning in the context of the hemoglobin (Hgb) and mean corpuscular value (MCV).
