A comparison of four commercial test kits for detection of cytomegalovirus antibodies in blood donors. Transfusion. 1986 Mar-Apr; 26 (2):203–204.Feng CS, Williams IB, Gohd RS, Causey AP. A comparison of four commercial test kits for detection of cytomegalovirus antibodies in blood donors. ...
Here the authors engineer a bispecific antibody (Ab) for HIV-1 by combining a gp41 N-heptad repeat targeting Ab with a CD4 binding Ab. Prepositioning via CD4 binding results in high neutralization breadth and potency, and experiments in HIV infected humanized male mice show reduction of viral...
health agencies have rolled out tests to diagnose and understand the disease. Besides the now widely known PCR test, there is interest in serological (blood) tests that detect “antibodies” against SARS-CoV-2, the virus that causes COVID-19. These blood tests...
To address this, an EUA approved immunoassay for detection of antibodies to SARS-CoV-2 in venous serum samples was investigated for use with dried blood spot (DBS) samples. Results from self-collected DBS samples demonstrated a 98.1% categorical agreement to venous serum with a correlation (R)...
this technology could make it possible for people to buy a blood sampling kit at a pharmacy or a supermarket, collect their own blood with a simple finger prick, and mail it to a central laboratory that analyzes the blood sample and returns the test results via email or a smart-phone app...
Results were compared to COVID-19 subjects and healthy blood donors from the United States. Prior to the pandemic, Sierra Leoneans had more frequent exposures than Americans to coronaviruses with epitopes that cross-react with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), SARS-...
One major job of serologists is to test serum for antibodies. Aserological test, also called anantibodytest, detects antibodies in the blood when the body’s immune system is responding to a specific infection. Serological tests determine yourserostatus: whether or not you have detectable antibod...
The lab performs daily calibrations on equipment and quality control checks test results for reliability, he said, and the lab could potentially process up to 500,000 coronavirus antibody tests per month. Dozens of blood tests are being marketed in the United States that are not entirely accurate...
Characteristics such as the detection of the immune response, the prevalence of nonpathogenic infestation, cross-reactivity with other microorganisms, etc., are very important in the interpretation of results. Another important general point to stress is that the detection of antibodies does not nec-...
Results are shown as mean ± SEM. Significance was assessed using an unpaired Student t-test. circulate in liver sinusoids of mice injected with the same dose of rituximab (Fig. 4B–E, Movie S3 and 4). Thus, distinct features of anti-CD20 Ab such as glycoengineering, but...
