COVID-19 Testing

Do You Need a Test?

Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headaches
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

Anyone with symptoms should get tested as soon as possible, stay away from others, and follow the instructions on how to isolate.

If you think you have been exposed to COVID-19, wait until at least 5 days have passed since the date you think you were last exposed before getting tested, unless you develop symptoms. Follow the instructions on how to quarantine after exposure to prevent further transmission. 

  • Testing immediately after exposure isn’t helpful because it may be too early in the incubation period and there isn’t enough viral material for the test to detect.
  • Some people may not become ill for up to 14 days. For that reason, people who believe they have been exposed to COVID-19 should monitor themselves for symptoms of COVID-19, even if they test negative before the full two weeks have passed.
  • Quarantining for a full two weeks is recommended if you have close contact with high-risk individuals or live or work in a congregate setting.
  • If you do not develop symptoms, there are options to shorten your quarantine period using a combination of symptom monitoring and testing if you do not have contact with high risk individuals.
  • If your test is positive, begin isolation for 10 days. 

 Do not go to an emergency room or call 911 unless you are having a medical emergency.

  • Call 911 or go to an emergency room for:
    • Symptoms of a heart attack or stroke
    • Difficulty breathing or choking
    • Difficulty speaking, walking, or seeing
    • An allergic reaction
    • Confusion, dizziness, or disorientation
    • Sudden, severe pain
  • Do not call 911 for:
    • A ride to the doctor's office
    • COVID-19 testing
    • Mild symptoms
    • Information about COVID-19

Types of Testing 

Molecular-Based (PCR) Testing

A molecular amplification test detects genetic material from a specific virus in patient samples. Most molecular tests for COVID-19 are called PCR tests; however, there are a few other molecular tests that are not called PCR. PCR is currently the best way to test for current infection with COVID-19. PCR molecular tests are processed in a lab and can take several days to return results. While this test detects current or recent infection from COVID-19, it is not useful in determining past exposure in fully recovered patients.

Antigen Testing

An antigenic test can quickly detect fragments of proteins found on or within the virus that causes COVID-19. The test is similar to a rapid flu test and is usually performed at the point-of-care by collecting a sample from the nasal cavity using a swab. Most antigen tests return results in approximately 15 minutes. While antigen tests can be less expensive and offer fast results, they are not as sensitive as PCR tests. This means a PCR test may be needed to confirm a test result in some situations. The FDA recently authorized the first COVID-19 antigen test for use in properly certified laboratories, as well as for point-of-care testing in hospitals and urgent care clinics.

Antibody (Serological) Testing

A serological test is a blood test that looks for antibodies in your blood. It can detect the body's immune response to the infection caused by the virus, rather than detecting the virus itself. While these tests can detect previous exposure to COVID-19, they cannot reliably determine if a patient is currently infected and able to spread the virus to others. A serologic test does not replace a viral test and should not be used to establish the presence or absence of a COVID-19 infection.  The CDC does not currently recommend using antibody testing  to assess for immunity to COVID-19 following COVID-19 vaccination or to assess the need for vaccination in an unvaccinated person.
