o defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the body itself. In a new proof-of-concept study in ACS Sensors, researchers describe a new system for detecting antibodies within a...

On Thursday, the US Food and Drug Administration announced that more than two dozen antibody tests sold to Americans have not been proven to work A Mayo Clinic experiment found that half of the ninee antibody tests it analyzed were unreliable Antibody tests detect immune proteins developed in response to an infection and may provide...
Development and validation of serological markers for detecting recent Plasmodium vivax infection Plasmodium vivax is the most widespread malaria parasite worldwide, with up to two billion people at risk of infection. As well as causing illness and death in its ‘active’ stage of infection, the parasite can hide as hypnozoites, a dormant stage, in the...
Researchers at Hokkaido University in Japan have developed a microfluidic test that can detect antibodies against a viral infection. So far, the test has been optimized to detect avian flu, but could be adapted to detect antibodies against the virus causing COVID-19. The device can provide a result in as little as 20 minutes and...
An antibody appears to make a big difference between multiple sclerosis and other disorders affecting the protective myelin sheath around nerve fibres, report Tohoku University scientists and colleagues in the journal Brain. The finding suggests that some of these ‘inflammatory demyelinating diseases’ belong to a different category than multiple sclerosis, and should be treated according...
by Lancet Older age, being male, deprivation, living in a densely populated area, ethnicity, obesity, and chronic kidney disease are associated with a positive test for COVID-19, according to results from 3,802 people tested for SARS-CoV-2 (including 587 positive tests) in the UK. The observational study was conducted in between Jan 28 and April 4...
The neutralizing antibody, called S309, is on an accelerated path toward clinical trials. An antibody first identified in a blood sample from a patient who recovered from Severe Acute Respiratory Syndrome in 2003 inhibits related coronaviruses, including the cause of COVID-19. The antibody, called S309, is now on a fast-track development and testing path at...
Made from viral proteins, Moderna’s COVID-19 vaccine is composed of synthetic viral mRNA. These molecules are injected into people and cellular protein-making machines, called ribosomes, read and translate the mRNA. It’s these proteins that then trigger an immune response. Credit: The Conversation, CC BY-SA Early morning on May 18, Moderna, a biotechnology company, revealed the...
Updated at 11:16 p.m. ET The Food and Drug Administration is cautioning the public about the reliability of a widely used rapid test for the coronavirus. The test, made by Abbott Laboratories, has been linked with inaccurate results that could falsely reassure patients that they are not infected with the virus. The Trump administration has...
