COVID-19 Testing Q & A

What is COVID-19?

COVID-19 is an infectious illness caused by a newly discovered coronavirus. Coronaviruses are a large collection of viruses that may cause a range of respiratory illnesses ranging from the common cold to more severe illnesses. 

The virus spreads through the droplets of saliva or nasal discharge that you expel when you cough or sneeze. 

While these droplets are airborne, your chances of infection are low unless an infected person coughs or sneezes near you or if you touch a surface a sick person might have touched after sneezing or coughing into their hands. 

What are the warning signs of COVID-19?

Like other viral upper respiratory infections, COVID-19 causes:

  • Fever
  • Shortness of breath
  • Tiredness
  • Dry cough
  • Nasal congestion
  • Runny nose
  • Sore throat

COVID-19 symptoms usually develop slowly. It’s also possible to have the virus but not have symptoms. 

Around 80% of people who get a coronavirus infection recover without any special treatment, and only one in six people with COVID-19 become very ill and experience difficulty breathing. 

Individuals who are at a heightened risk, such as those over the age of 65 or with an existing respiratory condition, should be especially careful and practice social distancing and exemplary hygiene.

What types of COVID-19 testing are available?

Mom's Choice Mobile Healthcare offers several types of COVID-19 testing. Your practitioner can help you choose the option that’s right for you and your family. 

Rapid antigen testing offers a quick turnaround time, and it’s the type most commonly offered at large-scale test sites. This approach uses a nose or throat swab to gather cells for screening. You usually get your results the same day, sometimes within a couple of hours. 

Polymerase chain reaction (PCR) testing is also sometimes called molecular testing. These tests look at the genetic material of a virus to determine the type. PCR tests can be done from a nose or throat swab, and some options need only a small volume of saliva for testing. 

There’s also a rapid PCR test, which can deliver results quickly. This is a good option if you need to make travel or other decisions based on your test results. 

If you have questions about COVID-19 testing, call the office for guidance. Scheduling an appointment is as easy as choosing a time online and completing some routine forms, so don’t delay.

COVID-19 Treatment Options

WHAT IS REGEN-COV (casirivimab and imdevimab)?

REGEN-COV is an investigational medicine used in adults and adolescents (12 years of age and older who weigh at least 88 pounds (40 kg)) who are at high risk for severe COVID-19, including hospitalization or death for:

  • treatment of mild to moderate symptoms of COVID-19
  • post-exposure prevention of COVID-19 in persons who are:
    • not fully vaccinated against COVID-19 (Individuals are considered to be fully vaccinated 2 weeks after their second vaccine dose in a 2-dose series [such as the Pfizer or Moderna vaccines], or 2 weeks after a single-dose vaccine [such as Johnson & Johnson’s Janssen vaccine]), or, are not expected to build up enough of an immune response to the complete COVID-19 vaccination (for example, someone with immunocompromising conditions, including someone who is taking immunosuppressive medications), and have been exposed to someone who is infected with SARS-CoV-2.
    • Close contact with someone who is infected with SARS-CoV-2 is defined as being within 6 feet for a total of 15 minutes or more, providing care at home to someone who is sick, having direct physical contact with the person (hugging or kissing, for example), sharing eating or drinking utensils, or being exposed to respiratory droplets from an infected person (sneezing or coughing, for example).

For additional details, go to, or someone who is at high risk of being exposed to someone who is infected with SARS-CoV-2 because of occurrence of SARS-CoV-2 infection in other individuals in the same institutional setting (for example, as nursing homes, prisons,).

REGEN-COV is investigational because it is still being studied. There is limited information known about the safety and effectiveness of using REGEN-COV to treat people with COVID-19 or to prevent COVID-19 in people who are at high risk of being exposed to someone who is infected with SARS-CoV-2. REGEN-COV is not authorized for pre-exposure prophylaxis for prevention of COVID-19.

The FDA has authorized the emergency use of REGEN-COV for the treatment of COVID-19 and the post-exposure prevention of COVID-19 under an Emergency Use Authorization (EUA).
