New Study Shows Protective Immunity Against COVID-19 Is ‘Robust’ and May Last Up to Eight Months or Longer Following Infection

Researchers find declining antibody levels in SARS-CoV-2 patients are offset by T cells and B cells that remain behind to fight off reinfection Questions remain regarding how long antibodies produced by a COVID-19 vaccine or natural infection will provide ongoing protection against SARS-CoV-2. However, a new study showing COVID-19 immunity may be “robust” and “long lasting” may signal important news for clinical laboratories and in vitro diagnostics companies developing serological tests for...

Researchers in Five Countries Use AI, Deep Learning to Analyze and Monitor the Quality of Donated Red Blood Cells Stored for Transfusions

By training a computer to analyze blood samples, and then automating the expert assessment process, the AI processed months’ worth of blood samples in a single day New technologies and techniques for acquiring and transporting biological samples for clinical laboratory testing receive much attention. But what of the quality of the samples themselves? Blood products are expensive, as hospital medical laboratories that manage blood banks know all too well. Thus, any improvement to how labs store...

Anticipated Influenza/SARS-CoV-2 “Twindemic” Has Not Developed, Says CDC, Much to the Relief of the Nation’s Medical Laboratories

The remarkably low number of influenza diagnoses makes it possible for clinical laboratories to stay focused on COVID-19 One positive note for clinical laboratories this winter is the fact that the number of biological samples being submitted for influenza (flu) testing have dropped significantly. This has given medical laboratories more resources for processing COVID-19 tests. Dark Daily’s sister publication The Dark Report covered this phenomenon in “Surprise! Many Fewer Cases of Flu in Us,...

New Test Under Development That Detects Breast Cancer within One Hour with 100% Accuracy Has Potential to Help Pathologists Deliver More Value

Such a test, if proved safe and accurate for clinical use, could be a useful diagnostic tool for anatomic pathologists What would it mean to anatomic pathology if breast cancer could be diagnosed in an hour from a fine needle aspiration (FNA) rather than a core biopsy? A new test created by researchers affiliated with Massachusetts General Hospital in Boston may be just such a game changer. Especially in remote locations where clinical laboratory resources are in short supply. Regardless of...

Coveted Blue Horseshoe Crab Blood is Keeping COVID-19 Vaccinations Free of Deadly Endotoxins, But Demand for This Blood Could Have Implications for Supply of Certain Clinical Laboratory Tests

Pathologists may be interested to learn that though a substitute for horseshoe crab blood has been available for nearly 20 years, it has not been widely adopted in the US Since the 1970s, the blue blood of the horseshoe crab has saved countless human lives by detecting deadly toxins in medical products, as well as its use in a number of medical laboratory tests. Now, that unique blood is playing a vital role in the fight against COVID-19 as well, by enabling pharma companies to ensure the...

University of Vermont Microbiology Laboratory Identifies Inefficiencies When Performing Pooled Testing for COVID-19

The key to success with pooled testing, says the lab’s director, is having the right personnel and equipment, and an LIS that supports the added steps Experts believe pooled testing for COVID-19 could reduce the number of standard tests for SARS-CoV-2 by conserving testing resources and cutting lab spending on tests and testing supplies. However, some clinical laboratories have found pooled testing causes inefficiencies due to the lab’s lack of staff, limitations of existing equipment, and...
