PCR tests excel during Covid-19 pandemic

In early 1990, at Analytica, in Munich, a young US-American researcher Kary B Mullis received the award for biochemical analytics for his 1983 invention: the polymerase chain reaction (PCR) – a success topped in 1993 by the Nobel Prize for chemistry. Mullis’ work revolutionised DNA copying, a process which, before PCR, had taken weeks. Whilst initially PCR was used to create digital…

Covid-19: CRISPR-based test gives GPs quick results

Recent research in Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) has identified two enzymes that can detect Covid-19 RNA as simply as a pregnancy test Jesús Pla, an eminent microbiologist at the Complutense University in Madrid, explained in our exclusive interview. CRISPR technology could help alleviate workloads in packed hospitals and expand testing to primary care and…

Triage aided by a quick sensitive test

Large proportions of patients can be safely triaged either to rule out discharge or rule in lifesaving management – if following the European Society of Cardiology (ESC) Guidelines Class I recommendation of two serial measurements of hs-cTnI on admission and after one hour, if there are assay specific cut off values for the 0/1 algorithms. The Pathfast hs-cTNI assay is an approved system to…

Beckman Coulter launches SARS-CoV-2 IgM antibody test

Beckman Coulter announced the launch of its Access SARS-CoV-2 Immunoglobulin M (IgM) assay in countries accepting the CE Mark. The new IgM antibody test demonstrated 99.9% specificity with 1,400 negative samples and 100% sensitivity at >18 days post symptom onset and post positive PCR. Beckman Coulter’s IgM assay is part of a full suite of testing solutions the company is developing to…

Accuracy of rapid covid test may be lower than previously suggested

The accuracy of a rapid finger-prick antibody test for SARS-CoV-2, the virus responsible for covid-19 infection, may be considerably lower than previously suggested, finds a study published by The BMJ. The results suggest that if 10% of people given the test had previously been infected, around 1 in 5 positive test results would be incorrect (false positive results). These conclusions contrast…

Lab automation – economic aspects and Covid-19

The academic teaching Karlsruhe Hospital, at the University of Freiburg, is the largest hospital providing tertiary care in the Middle Upper Rhine Valley. Every year, 63,000 in-patients and 180,000 out-patients are treated in the 1,500-bed facility with 50 departments and 30 out-patient clinics. Inevitably, a hospital of this size has a central lab. We spoke with Dr Horst Mayer, managing senior…

Needlestick Injuries are history

Injuries due to contaminated puncture devices are still the most frequent cause of accidents in hospitals. This is a significant source of danger for many employees in the healthcare industry. At this moment in time, there are already more than 20 bloodborne pathogens that we know of. The most dangerous are HBV, HCV and HIV. Recent studies show that it is up to ten times more likely for more…

New SARS-CoV-2 test to deliver results in under 5 minutes

Research and innovation hub Imec announced that it has started developing a groundbreaking SARS-CoV-2 test. Unlike current approaches (using blood, saliva, or a nasopharyngeal swab), the new test will identify SARS-CoV-2 virus particles in a person’s exhaled breath. The solution promises the accurate identification of a contagious case in less than five minutes.

POCT: Understanding sources of error

In an emergency, point-of-care-testing can provide results in minutes. However, sources of error must be understood to ensure result accuracy and confident diagnosis (particularly important during the current pandemic). Medical teams frequently use POCT devices to assess acutely ill patients; a hospital’s diagnostic laboratory is responsible for the analysers, plus training non-laboratory…

New device detects traumatic brain injury 'on the spot'

A method for detecting traumatic brain injury at the point of care has been developed by scientists at the University of Birmingham. Using chemical biomarkers released by the brain immediately after a head injury occurs, researchers are able to pinpoint when patients need urgent medical attention. This saves time in delivering vital treatment and avoids patients undergoing unnecessary tests where…

It is only 120 millionths of a millimetre in size but can bring entire countries to a standstill: the Corona virus. Even if it were to disappear one day, viral infections will still be among the most frequent and difficult-to-treat diseases in humans. Even decades of research have only produced a few standardized vaccines and strategies for treatment to combat just a small number of viruses. Nor…

COVID-19 testing at random? Here's a better idea

As COVID-19 infections begin to rise again, a novel testing strategy proposed by researchers at the University of Oxford at the start of the pandemic has become urgent once again. The strategy aims to bring the virus’s reproduction number (‘R’) down to below 1, by concentrating testing resources on particular groups in the population that are most likely to spread the infection to others,…
