Did you know that women are 10 times more likely than men to develop a thyroid condition, yet often remain undiagnosed due to medical bias and lack of awareness? We often see women present themselves to an emergency department with health concerns that are brushed off as “stress” or “weight-related” versus conducting diagnostic testing to identify the root cause. How can we address that? Don’t mis...

The World Health Organization estimates 3.7 billion people under age 50 (67%) globally have herpes simplex virus type 1 (HSV-1) infection, the main cause of oral herpes, and 491 million people aged 15–49 (13%) worldwide have a herpes simplex virus type 2 (HSV-2) infection, the main cause of genital herpes.  Although treatable, most HSV infections are often asymptomatic or unrecognized.  Moreover,...

Sickle cell disease (SCD) patients are at risk of developing multiple complications from transfusions, including alloimmunization to red blood cell antigens, delayed hemolytic transfusion reactions and hyperhemolysis syndrome (HHS). While HHS is a rare complication of repeat blood transfusions in patients with SCD, clinicians and the laboratory have important roles in its detection and management....

Six Sigma is a popular way to measure quality. Sigma metrics have been adapted for the clinical laboratory by incorporating observed accuracy, precision and total error allowed (TEa). In vitro diagnostic (IVD) manufacturers have used Six Sigma to assess the quality of their assays using a small number of well-controlled systems to generate the data. QuidelOrtho has developed a novel approach to as...

Reference intervals (RIs) are a fundamental decision support tool used by clinicians and lab professionals to interpret laboratory reports and assess an individual’s health status. The establishment of reference intervals, however, can be challenging due to many physiological factors that influence their values and heterogeneities that inherently exist in populations.   In this podcast, Dr. Lindy...

Each year 4.5 million lives are saved by blood transfusions thanks to blood donations. More than 118 million units of blood are donated worldwide every year but less than 10% of people who can donate blood will give. These repeat blood donors enjoy benefits of their own while providing their lifesaving gift. Donating blood burns 650 calories, reduces stress, provides an emotional lift and has phys...

Transfusion reactions are adverse events associated with the transfusion of whole blood or one of its components. They range in severity from minor to life-threatening and can occur during a transfusion, termed acute transfusion reactions, or days to weeks later, termed delayed transfusion reactions. Transfusion reactions may be difficult to diagnose as they can present with non-specific, often ov...
