Covid-19 Update: Testing, Monitoring, and Vitamins/Medications

COVID-19 Testing

For patients with symptoms, the sensitivity of both PCR and antigen tests is improved.

PCR is the most sensitive test but has a long turnaround; antigen testing costs money.


  1. PCR
      • QUEST: turnaround time 3 to 4 days
      • LA Curative site: turnaround time 2 days
      • Private sites can cost over $100
  2. Antigen testing: done in our office
      • 89% sensitive but drops to 70% if patient has no symptoms
      • Results back within 1 hour; costs $75

Exposed to COVID-19, no symptoms

  • Full incubation period is 14 days, but close to 80% develop COVID within 2 to 5 days of exposure.
  • A negative test does not exclude the disease and is not a guarantee you will or won’t get coronavirus.

Living in the house with someone positive for COVID-19

  • Do not share the same bathroom or bedroom, if possible.
  • Wear a mask in common areas.
  • You can contract COVID anytime during that period of infectivity of COVID-positive patient.
  • Typically, a patient is considered infectious for 10 days. Note this possible scenario: one could contract the disease on their day 10 and incubate for 13 days and come down with COVID a full 24 days after the initial patient first got sick.

Daily monitoring

  • Use an oximeter to monitor your oxygen saturation.
  • If consistently under 93%, go to the ER.
  • Monitor your symptoms and temperature daily.
