'Nirvana': Fast, portable test diagnoses Covid-19, tracks variants

Clinicians using a new viral screening test can not only diagnose Covid-19 in a matter of minutes with a portable, pocket-sized machine, but can also simultaneously test for other viruses—like influenza—that might be mistaken for the coronavirus. At the same time, they can sequence the virus, providing valuable information on the spread of Covid-19 mutations and variants. The new test, dubbed…

Cooking an egg in an X-ray beam

A team of scientists has been using the X-ray source PETRA III at the German Electron Synchrotron (DESY) to analyse the structural changes that take place in an egg when you cook it. The work reveals how the proteins in the white of a chicken egg unfold and cross-link with each other to form a solid structure when heated. Their innovative method can be of interest to the food industry as well as…

Low-cost and fast Covid-19 test uses pool of gargle lavage samples

In order to monitor and contain the spread of SARS-CoV-2 it is necessary to test large numbers of people on a regular basis in decentralized settings. Researchers of the Max Planck Institute for Evolutionary Anthropology and the Hospital St. Georg in Leipzig, Germany, have developed improved protocols for the detection of SARS-CoV-2. The method can detect a positive sample in a pool with 25…

First Covid-19 test 'made in Poland'

To date, testing for SARS-CoV-2 infection mostly has relied on RT-PCR performed on a nasopharyngeal specimen. This testing method is very unpleasant for a patient: the professional tester has to tilt the patient’s head back slightly about 45°-70° to straighten the passage from the front of the nose, insert the swab through the nostril parallel to the palate, and the swab should reach a depth…

A corona lab that fits in a suitcase

The PCR test is the most accurate tool to identify SARS-CoV-2. However, valid results are often available only after days. Moreover, the laboratory must be well equipped, have trained personnel and sufficient financial resources. All of this is usually a problem in Africa. A portable suitcase could help. In cooperation with several African universities, scientists at Leipzig University have found…

Covid-19 Antigen Test: CE Mark for easier sample collection

Siemens Healthineers announced CE mark has been achieved to use anterior nose swab sampling for the Clinitest Rapid Covid-19 Antigen test. This sampling method can be less cumbersome and time consuming for both the provider and the patient. The test is a point-of-care cassette test that does not require laboratory instruments or specialized lab personnel to administer, and it delivers results in…

Startup develops breakthrough IgG antibody test for Covid-19

ZTA Biotech, a Budapest-based biotech startup, has developed a Covid-19 antibody (IgG) test using the ELISA protocol. This new detection method represents a great step forward in determining if patients have had a coronavirus infection and if they might still have immunity to the disease. Early results have proven 100% in specificity after testing 280 samples, and 100% sensitivity by testing 260…

Mass spectrometry to improve Covid testing

A UK biotech laboratory has used mass spectrometry in a new approach to coronavirus testing. MAP Sciences developed a gargle test, which collects samples from the back of the throat, and avoids the unpleasant sensation of the current PCR (polymerase chain reaction) swab tests. From there, the sample is tested for coronavirus using mass spectrometry (MS) with high levels of accuracy.

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…

Major flaws in evidence base for COVID-19 antibody tests found

Major weaknesses exist in the evidence base for COVID-19 antibody tests, finds a review of the latest research published by The BMJ. The evidence is particularly weak for point-of-care tests (performed directly with a patient, outside of a laboratory) and does not support their continued use, say the researchers. Serological tests to detect antibodies against COVID-19 could improve diagnosis and…
