Two years into the pandemic, we’re getting some solid testing options finally available on a widespread basis — never mind that shortage of at-home rapid antigen tests (RATs) that happened over the ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

Mucor PCR testing of bronchoalveolar lavage (BAL) fluid showed high specificity in identifying invasive pulmonary mucormycosis (IPM) in lung transplant recipients, especially when used in conjunction ...

Magnetic resonance spectroscopy (MRS) is a non-invasive imaging technique that has the potential to quantify metabolites in vivo. Using Phosphorus MRS (31 P-MRS), a spectrum containing signals of high ...

Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...

Every American traveling abroad needs to take an antigen test to return to the United States. But the start of the trip is often even more cumbersome, as many other countries (nearly every one I have ...

While they've been the gold standard to identify positive coronavirus cases around the world for more than a year, PCR tests still aren't trusted by some social media users. An Oct. 4 Instagram post ...

As the COVID-19 infection continues to ravage the world, the advent of an efficient as well as the economization of the existing RT-PCR based detection assay essentially can become a blessing in these ...

New COVID-19 restrictions for international travel and other activities are fueling consumer demand for highly accurate polymerase chain reaction, or PCR, tests with rapid turnaround times. Some ...

Johns Hopkins researchers developed microdevices known as "theragrippers" that were designed to "latch onto intestinal mucosa and release drugs into the body" over an extended period of time. But they ...
