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).

Automated Urine Microscope Verified for Regional Laboratories

Automated Urine Microscopy examines a sample of urine under a microscope. It can check cells from the urinary tract, blood cells, crystals, bacteria, parasites, and cells from tumors. This test is often used to confirm the findings of other tests or add information to a diagnosis. More...

ABO Histo-Blood Groups Influence Makeup of Gut Microbiome

Recent genome-wide association studies yielded inconsistent, underpowered and rarely replicated results such that the role of human host genetics as a contributing factor to microbiome assembly and structure remains uncertain. More...

Multiplex PCR Panel Evaluated for Diagnosis of Pneumonia

Population based studies in the USA estimate the incidence of community-acquired pneumonia at 250 cases per 100,000 residents/year. At any given time, 1% of hospitalized patients receive treatment for hospital-acquired pneumonia, rendering pneumonia the most common healthcare-associated infection. More...

Early Differences in Cytokine Production Distinguish Severity of COVID-19

Most COVID-19 patients experience asymptomatic/mild symptoms, but some suffer critical symptoms requiring intensive care. It is important to determine how asymptomatic/mild patients react to SARS-CoV-2 infection and suppress virus spread. More...

Automated Urine Microscopy Analyzer Detects Uropathogen Morphology

Urinary tract infection (UTI) is an infectious disease frequently encountered in daily life and is a representative infection that can cause serious sepsis. UTIs are very difficult to diagnose, and unnecessary treatment with antibacterial drugs of conditions with positive urine culture due to asymptomatic bacteria and vulvar‐contaminated urine is often wasteful.

Panel of MicroRNAs Differentiates Uncomplicated and Severe Malaria in Children

MicroRNAs (miRNAs), which are rapidly released from damaged tissues into the host fluids, constitute a promising biomarker for the prognosis of severe malaria. More...
