The DxTerity COVID-19 Saliva at-Home Collection Kit detects the presence of the virus but does not confirm immunity or detect antibodies. DxTerity‘s molecular-based PCR test received approval from the Food and Drug Administration last month. The test differs from the quicker and less expensive antigen tests, which use a nasal swab or throat swab to detect the virus.
A single COVID-19 testing kit is listed for $110, and a 10-pack bundle is available for $1,000.
Test takers must spit into a tube provided by the kit. The saliva sample is then inserted into a plastic bag and packed back into the box for shipment to one of DxTerity‘s laboratories certified by the Clinical Laboratory Improvement Amendments. Customers are also granted prepaid express return shipping with the test and should expect to receive results within 24 to 72 hours of sample receipt at the laboratory. DxTerity’s test is currently the only COVID-19 testing kit on Amazon.
“We have demonstrated the reliability and quality of our COVID-19 testing solution with big business and now we want to expand access to customers at home and small businesses,” said Bob Terbrueggen, founder and CEO of DxTerity, when he first announced the collaboration with the company last month. “Amazon is the perfect partner for expanding access to millions of U.S. customers.”
The test may not be valid for all travel purposes because sample collection is unsupervised, according to the product description. The Centers for Disease Control and Prevention recommends saliva specimens should be collected under supervision.
Amazon joins other retail giants in offering at-home COVID-19 saliva tests. Costco offers both regular and those approved for travel requirements to Hawaii, Bermuda and some other destinations for $129.99 and $139.99, respectively. However, the test has several dozen one-star reviews, with most complaining about delayed shipping and poor customer service from provider AZOVA.
Breaking from its tentative recommendations on mask use thus far, the Centers for Disease Control and Prevention (CDC) said on Tuesday that using masks benefits wearers, which is a step beyond its previous declaration that said wearing masks would only protect those around them.
“Experimental and epidemiological data support community masking to reduce the spread” of the virus, the C.D.C. said in a document that details scientific evidence supporting mask use. “Individual benefit increases with increasing community mask use,” it said.
The unequivocal statements are a departure from the agency’s previous language, which suggested that “the latest science may convince” Americans to wear masks and that mask use could prevent an infected person from spreading the virus to others. “The main protection individuals gain from masking occurs when others in their communities also wear face coverings,” it said.
The agency also offered an economic argument, saying that increasing the proportion of people who wear masks by 15 percent could prevent the need for lockdowns and cut associated losses of up to $1 trillion, or about 5 percent of gross domestic product. The document also referred to a study of 124 Beijing households in which mask use significantly cut transmission of the virus, and an outbreak aboard the U.S.S. Theodore Roosevelt in which face coverings appeared to have reduced risk of infection by 70 percent.
The US Centers for Disease Control and Prevention (CDC) has updated its definition of a close contact with a Covid-19 patient to include multiple, brief exposures, director Dr. Robert Redfield said Wednesday.
The new definition includes exposures adding up to a total of 15 minutes spent six feet or closer to an infected person. Previously, the CDC defined a close contact as 15 minutes of continuous exposure to an infected individual.
The agency changed the definition after a report from Vermont of a corrections officer who became infected after several brief interactions with coronavirus-positive inmates – none of them lasting 15 minutes, but adding up over time.
“As we get more data and understand the science of Covid, we are going to incorporate that in our recommendations,” Redfield said at a news conference held at CDC headquarters in Atlanta. “Originally, contact that was considered to be high risk for potential exposure to Covid was someone within six feet for more than 15 minutes.”
Breast cancer is one of the most common cancers, and one of the leading causes of death in women globally. Breast cancer is a disease where cells located in the breast grow out of control. Although a majority of breast cancers are discovered in women at the age of 50 years or older, the disease can affect anyone, including men and younger women, according to the Centers for Disease Control and Prevention (CDC). Last year there were 9.6 million deaths and 18.1 million new cases of breast cancer diagnosed globally according to the latest report from the International Agency for Research on Cancer (IARC) released in September 2018.
In 2019 alone, the U.S. National Cancer Institute estimates that there will be 268,600 new female breast cancer cases and 41,760 fatalities. Earlier this month, researchers based in Switzerland published in Cell their study in using applied artificial intelligence (AI) machine learning to create a comprehensive tumor and immune atlas of breast cancer ecosystems that lays the foundation for innovative precision medicine and immunotherapy.
The study was led by professor Bernd Bodenmiller, Ph.D. at the Institute of Molecular Life Sciences at the University of Zurich in Switzerland. Bodenmiller is a recipient of the 2019 Friedrich Miescher Award, Switzerland’s highest distinction for outstanding achievements in biochemistry. His team worked in collaboration with the Systems Biology Group at IBM Research in Zurich led by María Rodríguez Martínez, Ph.D. with the shared goal to produce a foundation for more targeted breast cancer treatment through precision medicine.
