Lateral flow tests for COVID-19 can be very accurate and specific when used as directed, but introducing acidic fluids can cause the tests’ detecting antibodies to clump, which may read as a positive result.

The masks contain freeze-dried, cell-free biosensors, enabling them to detect pathogens including SARS-CoV-2.

The Scientist checks in on scientists who switched gears to combat the pandemic.

Glucometers are easy-to-use, cheap, and highly scalable. And they are 100 percent accurate at detecting SARS-CoV-2.

Skin symptoms are often the first, or only, symptom of COVID-19.

Two studies this month point to pooches’ quick detection of SARS-CoV-2 on material that touched the skin of infected participants, although the pups’ accuracy does not match that of RT-PCR.

In the largest effort to date to standardize performance metrics of the cancer diagnostic across products, researchers say the products can likely detect advanced tumors reliably, but early-stage malignancies would remain a challenge.

Free’s dip-and-read urinalysis allowed diabetics to monitor glucose levels at home, rather than at a hospital.

A noninvasive saliva test accurately identified concussions in a study of hundreds of rugby players.

The microbiome-testing company made misleading claims about its prospects and about its business strategy, which allegedly relied on fooling doctors into ordering unnecessary tests, according to the US government.

Last year’s Top 10 Innovations judges look into their crystal balls.

A finding of distinct patterns of gene-regulating RNA snippets in the blood of ME/CFS patients in response to a stress test could pave the way for a diagnostic tool for the condition and help untangle its underlying mechanisms.

A CRISPR-based, paper-strip test developed by Indian researchers performs as well as real-time PCR in identifying the presence of SARS-CoV-2 and returns results within an hour.
