Is it COVID-19? Flu? At-home rapid tests could help you and your doctor decide on a treatment plan
At-home rapid tests for COVID-19 and influenza are becoming available, allowing simultaneous diagnosis, which aids timely and effective treatment and improves patient outcomes.
A scratchy, sore throat, a relentless fever, a pounding head and a nasty cough – these symptoms all scream upper respiratory illness. But which one?
Many of the viruses that cause upper respiratory infections such as influenza A or B and the virus that causes COVID-19 all employ similar tactics. They target the same areas in your body – primarily the upper and lower airways – and this shared battleground triggers a similar response from your immune system. Overlapping symptoms – fever, cough, fatigue, aches and pains – make it difficult to determine what may be the underlying cause.
Now, at-home rapid tests can simultaneously determine whether someone has COVID-19 or the flu. Thanks in part to the National Institutes of Health’s Rapid Acceleration of Diagnostics, or RADx, program, the Food and Drug Administration has provided emergency use authorization for seven at-home rapid tests that can distinguish between COVID-19, influenza A and influenza B.
Our team in Atlanta – composed of biomedical engineers, clinicians and researchers at Emory University, Children’s Healthcare of Atlanta and Georgia Institute of Technology – is part of the RADx Test Verification Core. We closely collaborate with other institutions and agencies to determine whether and how well COVID-19 and influenza diagnostics work, effectively testing the tests. Our center has worked with almost every COVID and flu diagnostic on the market, and our data helped inform the instructions you might see in many of the home test kits on the market.
While no test is perfect, to now be able to test for certain viruses at home when symptoms begin can help patients and their doctors come up with appropriate care plans sooner.
A new era of at-home tests
Traditionally, identifying the virus causing upper respiratory illness symptoms required going to a clinic or hospital for a trained medical professional to collect a nasopharyngeal sample. This involves inserting a long, fiber-tipped swab that looks like a skinny Q-tip into one of your nostrils and all the way to the back of your nose and throat to collect virus-containing secretions. The sample is then typically sent to a lab for analysis, which could take hours to days for results.The COVID-19 pandemic made over-the-counter tests for respiratory illnesses commonplace.

Thanks to the COVID-19 pandemic, the possibility of using over-the-counter tests to diagnose respiratory illnesses at home became a reality. These tests used a much gentler and less invasive nasal swab and could also be done by anyone, anytime and in their own home. However, these tests were designed to diagnose only COVID-19 and could not distinguish between other types of illnesses.
Since then, researchers have developed over-the-counter multiplex tests that can screen for more than one respiratory infection at once. In 2023, Pfizer’s Lucira test became the first at-home diagnostic test for both COVID-19 and influenza to gain emergency use authorization.
What are multiplex rapid tests?
There are two primary forms of at-home COVID-19 and COVID-19/flu combination tests: molecular tests such as PCR that detect genetic material from the virus, and antigen tests – commonly referred to as rapid tests – that detect proteins called antigens from the virus.
The majority of over-the-counter COVID-19 and COVID-19/flu tests on the market are antigen tests. They detect the presence of antigens in your nasal secretions that act as a biological signature for a specific virus. If viral antigens are present, that means you’re likely infected. https://www.youtube.com/embed/s45GMoZaHFE?wmode=transparent&start=0 Respiratory illnesses such as flu, COVID-19 and RSV can be hard to tell apart.
To detect these antigens, rapid tests have paper-like strips coated with specially engineered antibodies that function like a molecular Velcro, sticking only to a specific antigen. Scientists design and manufacture specialized strips to recognize specific viral antigens, like those belonging to influenza A, influenza B or the virus that causes COVID-19.

The antibodies for these viral targets are placed on the strip, and when someone’s nasal sample has viral proteins that are applied to the test strip, a line will appear for that virus in particular.
Advancing rapid antigen tests
Like all technologies, rapid antigen tests have limitations.
Compared with lab-based PCR tests that can detect the presence of small amounts of pathogen by amplifying them, antigen tests are typically less sensitive than PCR and could miss an infection in some cases.
All at-home COVID-19 and COVID-19/flu antigen tests are authorized for repeat use. This means if someone is experiencing symptoms – or has been exposed to someone with COVID-19 but is not experiencing symptoms – and has a negative result for their first test, they should retest 48 hours later.
Another limitation to rapid antigen tests is that currently they are designed to test only for COVID-19, influenza A and influenza B. Currently available over-the-counter tests aren’t able to detect illnesses from pathogens that look like these viruses and cause similar symptoms, such as adenovirus or strep.
Because multiplex texts can detect several different viruses, they can also produce findings that are more complex to interpret than tests for single viruses. This may increase the risk of a patient incorrectly interpreting their results, misreading one infection for another.
Researchers are actively developing even more sophisticated tests that are more sensitive and can simultaneously screen for a wider range of viruses or even bacterial infections. Scientists are also examining the potential of using saliva samples in tests for bacterial or viral infections.
Additionally, scientists are exploring integrating multiplex tests with smartphones for rapid at-home diagnosis and reporting to health care providers. This may increase the accessibility of these tests for people with vision impairment, low dexterity or other challenges with conducting and interpreting at-home tests.
Faster and more accurate diagnoses lead to more targeted and effective treatment plans, potentially reducing unnecessary antibiotic use and improving patient outcomes. The ability to rapidly identify and track outbreaks can also empower public health officials to better mitigate the spread of infectious diseases.

A Legacy of Service: How family stories shape service
(Family Features) Major historical events like war or military service make a lasting impact on family identity, values and traditions, often reverberating across multiple generations. Veterans frequently speak about their military units as if they were family, given the unbreakable bonds that develop between comrades. However, for some veterans, “brothers in arms” is more than a figurative turn of phrase. Throughout the 20th century, entire families felt the firsthand effects of war, with multiple generations serving. Brothers enlisted together. A father’s military legacy inspired his children to join up. Sweethearts met and married while in uniform. These stories not only illustrate the experiences of individual veterans but also provide an intimate glimpse into family legacies of military service. Consider the Veterans History Project, a program overseen by the Library of Congress, which collects and preserves the firsthand remembrances of U.S. military veterans and makes them accessible for future generations to better understand veterans’ service and sacrifice. These personal stories encompass original correspondence, memoirs, diaries, photographs and oral history interviews, all offering deeper insight into the long-term impact of military service. Veterans’ narratives are collected by volunteers, and anyone who served from World War I to today can submit their personal story, regardless of whether or not they saw combat. The collections frequently shed light on the importance of family in military experiences. Whether expressed through heartfelt letters home, enduring family legacies of service or the experience of serving alongside loved ones, these stories reflect profound connections. Family Identity During the Cold War, Jennifer McNeill rose from Army Dental Assistant to Command Sergeant Major at the Army Eisenhower Medical Center in Fort Gordon, Georgia. Her collection includes a poignant photograph of her mother sharing images of her four military daughters in uniform, underscoring how family identity and military service are closely connected. Values Military service makes a lasting impression on veterans, shaping the experiences and the values that guide them through life. Ray Chavez is one such example. He was the oldest known Pearl Harbor survivor before his passing in 2018. For most of his life, he remained silent about his experiences, but in 1991, his daughter, Kathleen Chavez, who served in the U.S. Navy during Desert Storm, convinced him to return to Pearl Harbor. That trip marked the first time he spoke openly about his service. Kathleen shared their family’s deep military legacy in her oral history for the Veterans History Project. Traditions Across Generations Serving in the military is a deeply personal journey, but for many veterans, it’s an experience that transcends generations. Bill Toledo enlisted in the Marine Corps in October 1942 at the age of 18. Along with his uncle, Frank Toledo, and cousin, Preston Toledo, he served as a Code Talker transmitting military messages through secret codes. In his oral history, Bill vividly recalled both the challenges of combat during the invasion of Iwo Jima in February 1945, and the treasured moments spent with his uncle.

How C-reactive protein outpaced ‘bad’ cholesterol as leading heart disease risk marker
C-reactive protein (CRP) is a key inflammation marker that can predict heart attack and stroke risk—often better than LDL cholesterol. Here’s why it matters.
C-reactive protein is created by the liver in response to infections, tissue damage, chronic inflammatory states from conditions like autoimmune diseases, and metabolic disturbances like obesity and diabetes. Essentially, it is a marker of inflammation – meaning immune system activation – in the body. C-reactive protein can be easily measured with blood work at the doctor’s office. A low C-reactive protein level – under 1 milligram per deciliter – signifies minimal inflammation in the body, which is protective against heart disease. An elevated C-reactive protein level of greater than 3 milligrams per deciliter, signifies increased levels of inflammation and thus increased risk for heart disease. About 52% of Americans have an elevated level of C-reactive protein in their blood. Research shows that C-reactive protein is a better predictive marker for heart attacks and strokes than “bad,” or LDL cholesterol, short for low-density lipoprotein, as well as another commonly measured genetically inherited biomarker called lipoprotein(a). One study found that C-reactive protein can predict heart disease just as well as blood pressure can.
Why does inflammation matter in heart disease?
Inflammation plays a crucial role at every stage in the development and buildup of fatty plaque in the arteries, which causes a condition called atherosclerosis that can lead to heart attacks and strokes. From the moment a blood vessel is damaged, be it from high blood sugar or cigarette smoke, immune cells immediately infiltrate the area. Those immune cells subsequently engulf cholesterol particles that are typically floating around in the blood stream to form a fatty plaque that resides in the wall of the vessel. This process continues for decades until eventually, one day, immune mediators rupture the cap that encloses the plaque. This triggers the formation of a blood clot that obstructs blood flow, starves the surrounding tissues of oxygen and ultimately causes a heart attack or stroke. Hence, cholesterol is only part of the story; it is, in fact, the immune system that facilitates each step in the processes that drive heart disease.Fatty plaque buildup in the arteries causes a blockage that starves tissues of oxygen and can lead to a heart attack or stroke.wildpixel/iStock via Getty Images Plus
Does cholesterol still matter for heart disease risk?
Though cholesterol may not be the most important predictor of risk for heart disease, it does remain highly relevant. However, it’s not just the amount of cholesterol – or more specifically the amount of bad, or LDL, cholesterol – that matters. Two people with the same cholesterol level don’t necessarily have the same risk for heart disease. This is because risk is determined more so by the number of particles that the bad cholesterol is packaged into, as opposed to the total mass of bad cholesterol that’s floating around. More particles means higher risk. That is why a blood test known as apolipoprotein B, which measures the number of cholesterol particles, is a better predictor of risk for heart disease than measurements of total amounts of bad cholesterol. Like cholesterol and C-reactive protein, apolipoprotein B is also influenced by lifestyle factors like exercise, weight loss and diet. Nutrients like fiber, nuts and omega-3 fatty acids are associated with a decreased number of cholesterol particles, while increased sugar intake is associated with a larger number of cholesterol particles. Furthermore, lipoprotein(a), a protein that lives in the wall surrounding cholesterol particles, is another marker that can predict heart disease more accurately than cholesterol levels. This is because the presence of lipoprotein(a) makes cholesterol particles sticky, so to speak, and thus more likely to get trapped in an atherosclerotic plaque. However, unlike other risk factors, lipoprotein(a) levels are purely genetic, thus not influenced by lifestyle, and need only be measured once in a lifetime.
What’s the best way to prevent heart disease?
Ultimately, heart disease is the product of many risk factors and their interactions over a lifetime. Therefore, preventing heart disease is way more complicated than simply eating a cholesterol-free diet, as once thought. Knowing your LDL cholesterol level alongside your C-reactive protein, apolipoprotein B and lipoprotein (a) levels paints a comprehensive picture of risk that can hopefully help motivate long-term commitment to the fundamentals of heart disease prevention. These include eating well, exercising consistently, getting adequate sleep, managing stress productively, maintaining healthy weight and, if applicable, quitting smoking.Mary J.
