Holidays will look different this year for many Americans, with dinners outside, social distancing, or passing on family gatherings altogether. But several companies developing rapid at-home COVID-19 tests are hopeful that won't be the case next year. The goal is to make inexpensive, easy-to-use COVID tests that can deliver results in minutes, just like a pregnancy test. "For people to feel comfortable to associate with friends or family, there needs to be a testing methodology ideally that can be performed at home," said Tony Lemmo, CEO of the manufacturing company BioDot.The company's technology is being used by over 70 manufacturers worldwide making COVID-19 antigen, antibody, and PCR tests. Their automated platforms dispense nanoliter/picoliter amounts of reagent onto the tests accurately and fast.Lemmo says just one of their systems can support the production of roughly 100 million COVID-19 tests per year, helping to make high-volume production possible.“We knew we were going to be called on by customers to manufacture more equipment to provide them the ability to manufacture more tests," said Lemmo. To meet customer demand, BioDot increased staffing and built a new facility, compressing production time from months to weeks. The FDA recently authorized the first rapid at-home test that can deliver results in 30 minutes, eliminating the need for a lab to test the sample. But the molecular single-use test will only be available to patients with a doctor's prescription who are suspected of being infected with COVID-19.Companies developing tests hope the FDA will soon authorize another at-home testing tool: the rapid antigen test.These inexpensive tests provide results within minutes, and companies developing them say millions could be sold without a doctor's referral.“From what we’re hearing, it’s really just a matter of possibly months before there’s at least sufficient data to be able to support an at-home use of a test like an antigen test," said Lemmo.Lemmo says if authorized by the FDA, manufacturers could make millions of these tests in a matter of months. But antigen tests are less accurate, and the FDA wants to ensure they'll be simple enough for people to use at home. There are also concerns over how the data will be reported to health authorities. “I think any at-home testing or massive rollout of a test into the communities needs to be done very carefully and with a lot of education around it," said Clinical Lab Director Melissa Miller. Dr. Miller is a professor of pathology and laboratory medicine at the University of North Carolina Chapel Hill and Medical Director for the Clinical Microbiology Lab for the Medical Center.She worries the inaccuracies of these tests could eventually lead the public to lose trust in all testing. “Even at 98 percent specificity, which is very, very high. That means you’re going to have a false positive two out of every 100. If you started testing a hundred million people, this is millions of people who have a false-positive test," said Dr. Miller. She says this could lead to healthy people isolating and missing work or school unnecessarily, and false-negative results could give people a false sense of security. “These rapid antigen tests were pushed out to skilled nursing facilities; this is a very high-risk patient population. This is actually where you want a very accurate test," said Dr. Miller. She says it’s unclear how well antigen tests detect the virus in asymptomatic patients but agrees more data is needed to figure that out.“It might make more sense for K-12 schools, or even college settings, where there’s less risk for a poor outcome if you have a false positive or a false negative," said Dr. Miller. But with a growing demand for convenient at-home testing, manufacturers are hopeful that in the months ahead, the FDA will soon open the door to new solutions. 3889

  

High school seniors who plan on taking a gap year this fall to wait out the pandemic could be paying for it for the rest of their lives.While a one-year wait might seem like the right decision for students who don’t want to study online or risk COVID-19 exposure, graduating a year later could cost ,000 in lifetime earnings. A new study from the Federal Reserve Bank of New York details how taking a gap year could put students behind their peers financially and create an insurmountable earnings gap.According to the study, a 22-year-old college graduate earns ,000 on average the first year out of college, and can expect to make ,000 the year they turn 25. By contrast, if a student takes a gap year and delays graduation, they can expect to earn ,000 by age 25 — ,000 less. That gap will perpetuate and compound for late graduates throughout their careers.“Being a year behind, these differences add up each and every year, so that those graduating later never catch up to those who graduated earlier,” researchers Jaison Abel and Richard Deitz write in the report. “Together, these costs add up to more than ,000 over one’s working life, which erodes the value of a college degree.”College might cost even moreCollege typically gets more expensive every year, but this year might be an exception. A few colleges are freezing tuition or offering discounts, and students might see their living expenses decrease. Federal student loan interest rates are at historic lows as well.But experts don’t expect those trends to continue past the health crisis. And missing school this fall means you don’t get to take advantage of lower college expenses.Irma Becerra, president of Marymount University in Virginia, says colleges have had to make major investments to prepare for instruction this fall. Her school plans a hybrid-flex model that will allow students to blend in-person and remote learning based on their needs and comfort level.“Every university that I know has had to incur significant expense to deal with safely reopening or keeping staff and faculty on payroll,” Becerra says.She adds that while colleges are sensitive to the ripple effects of the economic downturn, she expects them to raise tuition in the future unless the government increases investments in higher education. “I can only imagine that [colleges] will have to raise tuition because we’ve all had significant expenses.”Students who opt for a gap year may also have to face higher tuition with less aid. According to Lindsay Clark, director of external affairs at the student finance app Savi, “Taking a gap year and deferring admission could affect scholarships or financial aid offerings if they are not guaranteed for the next year.”Is a gap year still worth the risk?While experts agree that making ,000 less during your lifetime is significant, they advise students not to base their gap-year decision on that figure alone.Arun Ponnusamy, chief academic officer at the college admissions counseling company Collegewise, points out that the return on investment for college is still substantial — even with a gap-year pay dip.A college graduate will make roughly a million dollars more than a high school graduate, according to Ponnusamy. “So we are talking about, you will lose 9% of that by sitting out a year? It just doesn’t sound like that is the number you should use to choose whether or not you sit out.”Martin Van Der Werf, associate director of editorial and postsecondary policy at Georgetown University’s Center on Education and the Workforce, advises students to consider their motivations for going to college and evaluate any anxieties they might have.As the father of a rising college freshman, Van Der Werf knows firsthand the difficult choices and serious implications facing students. He says that students who are experiencing anxiety about the fall may be best served by taking off a semester or two — despite potential wage loss.“The worst thing that could happen is you start college, you don’t finish and you have all this debt,” Van Der Werf says when talking about the potential for some students to be unsuccessful with remote learning. “Then you don’t have a degree to pay off that debt.”He advises students to keep their options open and pay attention to their school’s reopening plans. “There are colleges who announced that they were coming back but are going online. If that makes you uncomfortable, you shouldn’t do it.”More From NerdWalletDon’t Wait to Refinance These Student Loans‘Shadow’ Lenders Can Leave College Students in the DarkStudent Loan Refi Rates Keep Dropping, Should You Take the Plunge?Cecilia Clark is a writer at NerdWallet.

Health care worker Amanda Solt is one of the lucky COVID-19 patients who survived the disease.“I remember them pulling my arms up over my head, under my pillow and then they took the pillow, and that's the last thing I remember,” said Solt.She was in the hospital and ICU for weeks back in June. It wasn't until she received a convalescent plasma donation that she started to turn a corner.“They helped me hold the phone up to my ear, so I could give a verbal consent. To help me sit me up in the bed, literally, they were holding me and helping me sign the paper, so I could give consent. And I just remember the nurses were like, ‘say yes.’ Yes, I remember that and honestly, I feel like I owe my life to them and to the person who donated for sure.”The nurses helped Solt take a picture the moment she got the plasma. She says it saved her life and now she's advocating for others to donate.Health and Human Services Secretary Alex Azar also pushed for donations Wednesday during a briefing on vaccines. HHS is increasingly concerned about supply with rising cases.Plasma is given to hospitalized patients earlier now.People with COVID antibodies can donate plasma as often as every seven days for up to three months. Just one donation can help up to four people.“You have the chance to truly, truly make a difference in life or death for somebody,” said Solt.The American Red Cross saw their distributions of convalescent plasma increase 250% in November compared to September. You can make an appointment to donate online through their app or over the phone. 1571
