You Don’t Actually Have Influenza
If your rapid test comes back negative, it is possible that you do not have influenza. Flu-like illnesses can be caused by other viruses that cause more severe symptoms than a cold. Viruses such as adenovirus, coronavirus, parainfluenza, and respiratory syncytial virus can cause all of the miserable flu symptoms, but do not respond to antiviral medications that are effective against influenza.
While these viruses can certainly leave you feeling awful for a few days, they are less likely than influenza to lead to serious complications, secondary infections, or death.
Are There Different Types Of Flu Tests
In a lab setting, there are a few different ways to test for influenza. The most common test for flu is called a “rapid influenza diagnostic test” . These RIDTs detect the part of the virus that stimulates an immune response, known as an antigen, the CDC says. Another type of flu test, called a “rapid molecular assay” detects the actual genetic material of the flu virus. Both of these tests are termed “rapid” because they can provide results in 1015 minutes or 1520 minutes .
Even more accurate than RIDTs and rapid molecular assays are tests most often found in hospitals or public health laboratories . Those tests are known as: reverse transcription polymerase chain reaction tests, viral cultures, or immunofluorescence assays, the CDC says. These results also take a little longerup to several hours.
But as far as you’re concerned, all of those tests require the same thing from you: a nasal swab, where a provider swipes the inside of your nose or a throat swab, Cassandra Pierre, MD, MPH, an infectious disease physician at Boston Medical Center, tells Health. Even more specifically, some tests go further back in the nose, while the rapid test only goes right inside, Anjali Mahoney, MD, MPH, a family medicine specialist with Keck Medicine of USC, tells Health.
When To Get Tested
When it is flu season and a healthcare practitioner wants to determine whether your symptoms are due to seasonal influenza A or B or to another cause within 3 to 4 days of the onset of signs and symptoms, such as fever, headache, muscle aches, sore throat, weakness, fatigue, cough, sore throat, stuffy nose and sometimes runny nose

How Long Do Results Take From A Pcr Covid Test
Most people typically get their result the next day, but it can take up to three days.
NHS Test and Trace figures show around 95 per cent of people get a result in 24 hours if they are tested under Pillar 1, which covers places like hospitals and outbreak spots.
But around 60 per cent of those tested at large drive-through centres, under Pillar 2, get their result back in 24 hours.
The figure is lower for those that do their test at home.
The turnaround time has historically fluctuated depending on the Covid outbreak at the time.
For example, results may take longer to come back during very busy periods or peaks of waves because labs are swamped with tests.
Usually the result is sent to you via text or email when it’s ready. If you have the NHS Covid-19 app, the result might come to you that way.
If you do not get your results by day six, then call 119. Calls to 119 are free from a landline or mobile phone. Lines are open from 7am to 11pm.
Other Ways To Reduce Your Risk For The Flu Or Flu Complications
Increase your chance of staying healthy by:
- often, especially during winter months when the flu is most common.
- Keeping your hands away from your nose, eyes, and mouth. Viruses are most likely to enter your body through these areas.
- Eating a healthy and .
- Getting regular exercise.
- Not smoking. Smoking irritates the lining of your nose, sinuses, and lungs, which may make you susceptible to complications of the flu.

When Is The Best Time To Get A Rapid Flu Test
Theres no hard and fast rule with a rapid flu test, according to Dr. J.D. Zipkin, Associate Medical Director with Northwell Health-GoHealth Urgent Care. Symptoms for the flu can vary from one person to the next and from one flu season to the next.
However, if a patient presents with what appears to be the flu, doctors are going to treat for the flu. This could mean prescribing antiviral drugs or other medications to help alleviate your flu symptoms until the virus has naturally taken its course.
The best utility for a rapid flu test is when symptoms are not necessarily indicative of the flu, said Zipkin, when youre trying to distinguish between the flu and another upper respiratory infection. And since the antiviral medications used to treat flu only work if you start them within the first two days of illness, its important to come in for testing and treatment right away.
Rapid flu tests, or rapid influenza diagnostic tests, are also recommended by the Centers for Disease Control and Prevention during an acute respiratory disease outbreak to determine if influenza is the cause, and to subsequently ensure public health preventative and control measures are in place within the community.
Everything You Need To Know About Rapid Flu Tests
Its the dead of winter and all of a sudden youre not feeling well. Your bodys achy all over and youve developed a fever, cough and sore throat. Thinking about all the things on your to-do list, you try to resist the urge to climb back in bed.
You believe you mightve gotten the pesky flu. But it could just be flu-like symptoms, but not actually the flu, such as the common cold or strep throat. All you know is you want to start feeling better, and fast.

How Do They Decide What Strains Are In The Vaccine Each Year
Each year, the flu vaccine, containing inactivated virus, is targeted to protect against the expected strains, based on the observations and experience of healthcare practitioners and scientists. Healthcare providers and researchers carefully track the influenza virus circulating worldwide and try to anticipate the strain that will eventually appear locally the next season.
As influenza travels through communities around the world, it undergoes spontaneous changes that allow it to evade the protective antibodies formed from previous infections and vaccinations. The amount of “antigenic drift” varies from year to year. Bigger antigenic drifts, known as “antigenic shifts,” result in more severe illnesses since more people will be susceptible to the virus.
Sometimes the flu strain will have significant antigenic drift during the season so that the virus will appear slightly different to the body’s immune system, decreasing the effectiveness of the vaccine’s protection. Or, the flu that predominates may end up being an unexpected strain, not the ones that the vaccine was developed to protect against.
Usually, in these cases, the vaccination will at least lessen the severity of the infection. In individual high-risk patients , healthcare practitioners may bolster the protection by prescribing antiviral treatments before the person gets sick to provide short-term protection while influenza moves through the community.

PCR tests are a cruicial tool in the prevention of Covid spread.
Waiting for the results can be an agonising wait, as it could be the difference between freedom and ten days of self-isolation.
If you’ve got symptoms of the virus, you’ll be wondering if you can get a test.
You need to self-isolate straight away until you get your results.
Do not leave home, except to post a test kit or for a PCR test appointment.
But some experts say you should get a Covid test if you feel unwell with cold or flu-like symptoms to be on the safe side.
You can also do a lateral flow test at home which takes just 30 minutes. This can give an indication of Covid infection.
Interpretation Of Rapid Influenza Diagnostic Test Results
Proper interpretation of RIDT results is very important for clinical management of patients and for assessing suspected influenza outbreaks. A number of factors can influence the results of RIDTs. The accuracy of RIDTs depends largely on the conditions under which they are used. Understanding some basic considerations can minimize being misled by false-positive or false-negative results.
- A negative result means that the RIDT did not detect any influenza viral antigen.
- The negative predictive value of an RIDT is highest when influenza activity is low in the population being tested .
- A negative result is most likely a true negative result if the respiratory specimen was collected close to illness onset during periods of low influenza activity in the population being tested .
- The negative predictive value of an RIDT is lowest when influenza activity is high in the population being tested .
- False-negative results are more likely to occur when influenza prevalence is high in the community.

How Long Does The Flu Test Take
For both types of rapid flu test, your healthcare provider may use a nasal swab to wipe the inside of your nose or throat swab on the back of your throat. This testing portion takes only a few seconds, then the swab will be tested and youll wait for your results.
The time to get your results varies a bit depending on which test your provider uses. The rapid influenza diagnostic test gives the fastest result in 10 to 15 minutes. A rapid molecular assay will give you results in 15 to 30 minutes. Youll simply wait in the doctors office, and your healthcare provider will return once results are available.
Clinicians could choose instead to squirt some saline in your nose and collect the liquid for diagnostic testing instead of using the swab.
Can I Have Flu And Covid
Yes. It is possible to have flu as well as other respiratory illnesses including COVID-19 at the same time. Health experts are still studying how common this can be.
Some of the symptoms of flu and COVID-19 are similar, making it hard to tell the difference between them based on symptoms alone. Diagnostic testing can help determine if you are sick with flu, COVID-19, or another respiratory infection.

How Is The Flu Treated
Most kids with flu get better at home. Make sure your child:
- drinks lots of liquids to prevent dehydration
- gets plenty of sleep and takes it easy
- takes acetaminophen or ibuprofen to relieve fever and aches. Don’t give kids or teens aspirin because of its link to Reye syndrome.
- wears layers that are easy to remove. Kids might feel cold one minute and hot the next.
Children with the flu should stay home from school and childcare until they feel better. They should go back only when they haven’t had a fever for at least 24 hours without using a fever-reducing medicine. Some kids need to stay home longer. Ask the doctor what’s best for your child.
Doctors may prescribe antiviral medicine for a very ill child or kids are at risk for more serious symptoms. The medicine can shorten the flu by 12 days. It works best if children start taking it within 48 hours of the start of the flu. If a doctor prescribes antiviral medicine for your child, ask about any possible side effects. Doctors won’t prescribe antibiotics for the flu. Antibiotics work only against bacteria, not viruses.
How Is The Flu Diagnosed
Its common for health care providers to diagnose the flu basedon symptoms and an exam, especially during flu season when the flu isgoing around your community. Often times a flu test isnt performedbecause testing positive for the flu doesnt change the recommendedtreatment. However, your health care provider will likely suggest aflu test if you are at high risk for serious complications from theflu. In addition, if you are admitted into the hospital because yourprovider suspects you may have the flu, you will likely be tested forthe virus.

Influenza Rsv And Covid
With many Americans returning to school and work and more people spending time indoors due to the change in weather, now is the time to be vigilant when it comes to influenza, RSV, and COVID-19. The 2019-2020 flu season, which ran from October 2019 through March 2020, had case totals between 39 to 56 million and medical visits between 18 to 26 million, according to estimates from the Centers for Disease Control and Prevention. For RSV, the CDC reports 2.1 million outpatient visits and 57 thousand hospitalizations in children under 5 years of age, with 177 thousand hospitalizations and 14 thousand deaths in adults over 65. COVID-19 cases are nearing 7 million with deaths over 200 thousand. So, if you are showing signs of the symptoms in the chart above, it is important to know whether you have COVID-19, influenza, or RSV. The only way to be sure is through diagnostic testing.
GENETWORx is offering the Flu A-B/COVID Combo Test to detect both strands of influenza, RSV, and COVID-19 all from a single sample. With this combination of tests, healthcare providers can provide an accurate diagnosis to patients and treat them with the appropriate measures. The GENETWORx Flu A-B/COVID Combo Test is a combination of two molecular assays.
Can The Flu Be Prevented
There’s no guaranteed way to avoid the flu. But getting the flu vaccine every year can help. Everyone 6 months of age and older should get it each year.
Most doctor’s offices, clinics, and drugstores offer the flu vaccine from September to mid-November. It’s best to get it before the end of October. But even if you don’t get it at the start of the flu season, it’s not too late to get one while the flu is still going around.
If your child is sick, has a fever, or is wheezing, talk to your doctor to see if you need to reschedule the flu vaccine.

How Accurate Is The Flu Test
Accuracy of the flu test depends on which kind of test isperformed and the type of influenza thats going around. While RIDTsare the most common flu tests, they are not as accurate as othertypes of flu tests, but they seem to be better at detecting the fluin children than adults. In general, if you receive a positive rapidtest during a flu outbreak, it likely means youre infected with theflu. Note that false negative and false positive test results can occur.
How Is The Test Used
Influenza testing may be used to help diagnose an influenza infection and help make treatment decisions. Sometimes influenza testing is used to help document the presence of influenza in the community or to help determine whether an outbreak of flu is occurring, especially in settings such as nursing homes and schools. Testing may be used to identify the type and/or the strain of influenza causing infections.
Not all cases of influenza require testing for antiviral treatments to be prescribed. Healthcare practitioners may diagnose and treat influenza without testing if the person has typical signs and symptoms of the flu, plus it is the flu season and it is known that the flu has reached a community. If it is outside the 3 to 4 day window when antiviral treatment is most effective and there is no evidence of severe illness or secondary complications, the person may simply be sent home to rest, drink fluids, and soothe symptoms with over-the-counter remedies.
However, the flu can be deadly. Testing can help healthcare practitioners minimize its spread and prescribe antiviral drugs to treat patients to lessen its severity, if it is diagnosed early. The Centers for Disease Control and Prevention recommends testing in certain situations:
