COVID-19 symptoms and test information

Is it COVID-19, flu, or RSV?

Influenza and respiratory syncytial virus (RSV) infections have similar symptoms to COVID-19 and are most common during the same time of year—late fall through winter. Plus, they are all contagious viruses that can be spread easily through person-to-person contact, including coughing and sneezing.

That’s where the similarities end. COVID-19, flu, and RSV respond best to different treatments, so it’s important to pinpoint the specific illness you have through testing. Talk to your doctor about your symptoms and what test option may be best for you.

Frequently asked questions about COVID-19 testing at Quest

About COVID-19

Though the COVID-19 Public Health Emergency was ended in May 2023, COVID-19 remains a serious health concern. According to the World Health Organization, confirmed COVID-19 cases continue to occur around the world.

In fact, COVID-19 cases are expected to peak between late fall and early winter, which is typical for a respiratory virus like COVID-19 or the flu.

Symptoms of COVID-19 include fever, loss of smell, coughing, sore throat, shortness of breath or difficulty breathing, feeling weak or lethargic, chills, muscle pain, lightheadedness or dizziness, headache, vomiting or diarrhea, slurred speech, and/or seizures.

The Centers for Disease Control and Prevention (CDC) offers many resources on COVID-19, including information about symptoms.

The symptoms of COVID-19 can be very similar to other respiratory infections like influenza (flu) or respiratory syncytial virus (RSV). Different tests are available to help determine which illness is making you sick.

If you suspect you may have COVID-19, contact your doctor or an authorized healthcare provider immediately for guidance. Your healthcare provider can review your symptoms to determine what testing is appropriate. To help you and your doctor determine if you have COVID-19, current infection testing is available at your doctor's office.

About Quest COVID-19 testing options

If you suspect you have COVID-19 or were recently in contact with someone who had it, a swab test can tell you whether you have a current infection. Knowing if you currently have COVID-19 gives you the information you need to self-isolate and protect everyone around you.

If you suspect that you had a recent or prior COVID-19 infection, even if you never showed signs of being sick, you can take an antibody blood test to confirm prior infection.

Understanding your antibody status also gives you and your healthcare provider the insight to make an informed decision about returning to activity. Other reasons why it’s beneficial to know if you are positive for COVID-19 antibodies include

Tracking evidence of your antibodies over time
Encouraging those you were in contact with to talk to their doctor about getting tested
Reducing the need to be monitored and retested for COVID-19 infection

Yes, and Quest labs are leaders in processing the complex COVID-19 testing.

For diagnosis of a current COVID-19 infection, while at your doctor's office, ask your doctor or healthcare provider to collect a sample and send it to Quest for testing. You can also check to see if you’re eligible for a no-cost test.

Current COVID-19 infections may also be detected with a rapid antigen test. Results are typically ready in just 15 to 30 minutes. Testing is for ages 2+, regardless of symptoms.

If your healthcare provider is unsure what is causing your respiratory symptoms, they may recommend a COVID-19 and flu or a COVID-19, flu, and RSV combination test. A single sample is collected via nasal swab to be tested for multiple viral infections. The test results of this combination test will confirm or rule out each of the viral infections.

If you may have already been exposed to COVID-19, you may be eligible for antibody testing. To get tested for COVID-19 antibodies, you can order the test for yourself via questhealth.com. This allows you to get tested without waiting to go to your doctor first. Or, you can reach out to your doctor or healthcare provider and have them submit an order for your test.

Yes. Getting tested for COVID-19, flu, and RSV at the same time is called a combination test. This test is available at your doctor's office.

The symptoms of COVID-19 can be very similar to other respiratory infections like influenza or respiratory syncytial virus (RSV). Different tests are available to help determine which illness is making you sick.

With just 1 combination test, you and your doctor can determine if you have COVID-19, flu, or RSV. It eliminates the need for multiple tests or doctor visits, and can help you get the right treatment plan as soon as possible.

The cotesting approach helps increase testing capacity, especially during the busy flu season, and speeds up the time to a diagnosis.

Yes, several types of COVID-19 tests can be purchased online through the questhealth.com, including

The cost of tests through questhealth.com cannot be submitted to health insurance.

About long COVID testing

Sometimes referred to as long-haul COVID, chronic COVID, post-COVID condition, or post-acute sequelae of COVID-19, the CDC defines long COVID as health problems that last at least 3 months after first infection with the coronavirus.

While the reason is still unclear, these long-term effects may increase the risk of diabetes, heart conditions, autoimmune disorders, and neurological conditions.

Yes, you can still be tested for long COVID even if you never tested positive for COVID-19.

While most people with long COVID have evidence of infection or COVID-19 illness, according to the CDC there are some cases in which a person with long COVID may not have tested positive for the virus or known they were infected.

How to get COVID-19 testing through Quest

Quest has strong safety procedures in place at all times to protect patients and employees from coming into contact with any infectious diseases. Since the COVID-19 pandemic began, we have added more precautions that make it easier to access the testing you need from Quest.

These measures are still in place today and include

Encouraging online scheduling to limit your wait time and the number of people in waiting rooms
Encouraging patients with severe symptoms (fever or flu-like symptoms) to reschedule for when they are feeling better
Recommending that patients feeling unwell should protect themselves and others by wearing a mask
Offering a text alert option that allows patients to wait for appointments outside

COVID-19 test results

According to the CDC, a positive COVID-19 PCR test result means the virus was detected. That indicates you currently have or recently had a COVID-19 infection.

With a negative COVID-19 test result, the virus was not detected.

But false positives and false negatives are possible, especially with antigen tests that have a lower level of accuracy than molecular tests. Repeat testing is recommended in some cases, such as:

If an antigen test shows a positive result, but you do not have any symptoms and haven’t been exposed recently
If an antigen test shows a negative result, but you do have symptoms

The turnaround time for COVID-19 test results varies from 15 minutes to 2 days depending on the type of test you receive. The rapid antigen test takes 15-30 minutes to get results. Current infection testing results for COVID-19 alone are typically ready by the end of the following day. COVID-19 and flu combination tests or COVID-19, flu, and RSV combination tests typically take 1-2 days.

COVID-19 test costs

If you are uninsured, there are many ways to get tested.

Patients without insurance who are symptomatic or exposed are eligible for no-cost COVID-19 testing at select Quest Diagnostics locations, funded by the US Department of Health and Human Services (HHS)

The Increasing Community Access to Testing (ICATT) is a goverment-sponsored offering that first made COVID-19 testing available for those at greater risk of being affected by the pandemic. Since the pandemic is no longer considered a public health emergency, the qualifications for this program have been narrowed to those who are uninsured. This allows the ICATT program to continue serving the community and effectively manage the spread of COVID-19.

Footnotes

^a Positive results with the antibody test may occur after COVID-19 vaccination, but the clinical significance is not yet known. How long antibodies remain detectable after infection or vaccination and how long protection, if any, may last is not yet known. The results of this test should not be interpreted as an indication of degree of immunity or protection.

^b Rapid antigen tests are less accurate than molecular tests, so your doctor may recommend a molecular test when your antigen test result does not make sense with your symptoms and exposure history. For example, when the antigen test says you are infected, but you do not have symptoms (and have not been exposed recently). Another example is when your antigen test says you are not infected, but you have symptoms. Rapid antigen tests have their best accuracy within 7 days of symptoms starting. Accuracy and the clinical significance of results beyond the 7 days is not known.
