Our fully equipped, physician-led urgent care center is pleased to offer rapid PCR testing for COVID-19 seven days a week, so you can quickly find the answers you need to safeguard your health and the health of those around you.

What Is Rapid PCR Testing?  

Polymerase chain reaction (PCR) testing is the “gold standard” of COVID-19 diagnostics. It may also be referred to as molecular testing. PCR tests work by detecting the genetic material of SARS-CoV-2, the name of the novel coronavirus that causes the respiratory illness known as COVID-19. While it used to take several days to receive results from a PCR test, Lifeline Urgent Care now has the technology to offer same- or next-day results.

How Does Rapid PCR Testing Differ From Other Types of COVID-19 Tests?  

Today’s main test types that diagnose active COVID-19 infections are PCR and antigen. Antigen testing (often referred to as rapid antigen testing) screens for protein related to SARS-CoV-2 instead of its genetic material. Results of rapid antigen tests are typically available in a matter of minutes, but they tend to be less accurate than PCR tests. Both rapid antigen and rapid PCR testing involve a nasal or nasopharyngeal swab.

When Should I Be Tested for COVID-19?  

Anyone who believes he or she may have been exposed to the virus should receive a COVID-19 test, even if no symptoms are present. However, it’s particularly important to be tested if you are noticing potential signs of COVID-19. According to the Centers for Disease Control and Prevention (CDC), the most common symptoms of this illness include:

  • Shortness of breath

  • Chills or fever

  • Fatigue

  • Loss of smell or taste

  • Headache

  • Cough

  • Body or muscle aches

  • Sore throat

  • Runny nose or congestion

  • Diarrhea

  • Nausea or vomiting

Symptoms tend to appear within two to 14 days after exposure to the virus. It’s best to isolate and wait about three days after suspected exposure to receive testing, as it may take a few days for the virus to build up in your system and become identifiable on a rapid PCR test (with this said, PCR testing is known to deliver more accurate results sooner than antigen testing).

When to Call 911  

COVID-19 symptoms may become severe and life-threatening in some cases. Call 911 immediately if you or someone around you:

  • Is having difficulty breathing

  • Is experiencing persistent chest pain or pressure

  • Suddenly becomes confused

  • Has skin, lips, or nail beds that appear blue or gray due to lack of oxygen

  • Has lost consciousness

When speaking with a 911 operator, inform him or her that the affected individual may have COVID-19, if possible.
