COVID Rapid Antigen Testing Now Available at Oasis

There are several options available for COVID-19 testing, which I review in the video below. Rapid Antigen Testing is now available at Oasis. Please contact the office if you have questions or want to schedule an appointment.

Please watch my video below for the details.

Rapid Nasal Antigen Test for COVID (This is the new one available at Oasis.):
  • Results in ~20 minutes.
  • Nasal swab.
  • Measures proteins from the virus.
  • $85.  No insurance billing.
  • This test for the actual SARS-CoV2 virus proteins itself and is the only one of all these tests that does.
  • Should be done NO SOONER than 3 days after exposure but preferably no sooner than 5 days after exposure or can be done as soon as day 1 of symptoms.
  • Positive Percent Agreement (sensitivity): 96.7%
  • Negative Percent Agreement (specificity): 99% 
  • This means that a positive result is highly accurate (nearly 100% accurate), but a negative result does not completely rule out infection (though 96% is still relatively good if not done too soon) so it becomes more useful if repeated a day or two later if there is strong suspicion.

Rapid Blood Antibody Test for COVID IgM/IgG:
  • Blood test.
  • Results in ~20 minutes.
  • $85 (increased from $60).  No insurance billing.
  • Should be done NO SOONER than 5 days after exposure which is the soonest that IgM antibodies show up.  IgG antibodies show up by day 17 after exposure.  So for someone to get their money's worth, the test should be done 17 or more days after exposure but if someone does it after just day 5 of exposure the IgM antibody reading does tell potential exposure.
  • Is very accurate overall.  Above 95% and likely closer to 99%.

For COVID PCR swab testing: 
  • Oasis can do it via Quest, but results are back within more than 7 days which makes the utility of getting the test almost nil.  This is the test that we recommend to people, so you can instead go to, since they are still getting results back to folks in 24-48 hours. Appointments there are more limited, but I think they release more appointment slots each day in the evening.  Testing through is free.

Definitions of sensitivity and specificity:
  • Sensitivity (PPA) measures how often a test correctly generates a positive result for people who have the condition that’s being tested for (also known as the “true positive” rate). A test that’s highly sensitive will flag almost everyone who has the disease and not generate many false-negative results.
  • Specificity (NPA) measures a test’s ability to correctly generate a negative result for people who don’t have the condition that’s being tested for (also known as the “true negative” rate). A high-specificity test will correctly rule out almost everyone who doesn’t have the disease and won’t generate many false-positive results.

Have a great week, be healthy and stay safe, and as always, please feel free to pass this along!

  1. I can’t believe this is really true I never believe there is cure to this HSV 2/Herpes because all the hospital have told me there is no cure to it, few months ago I saw this man email Dr.Ogudugu on internet from a testimony share by someone who he help with his herbal cure I contact his email and ask for his help also, that is how he inform me about the cure process and this man sent me a herbal medicine which I took according to the way he instructed.

  2. I was infected with Genital Herpes Virus six months ago, ever since then i have been searching for cure everywhere because i was feeling so uncomfortable with it. I have been dating for almost 5 years until i contracted Genital Herpes from my ex-boyfriend. Since then i became very sad about the whole situation, always going online checking if i could get a cure to Genital Herpes, then i came across so many testimonies. Due to my seriousness and eagerness to be completely cured, i became a victim of fraud after contacting several so-called herbal doctors i was referred to. I lost a lot of money but i didn't stop searching for a cure. Then one faithful day, i came across a testimony of a lady saying that she got her Genital herpes cured by a Great Herbal Doctor she called Dr Ogudugu by contacting him through his email address. And she advised anyone with Genital Herpes or Simplex Herpes to contact the herbal doctor for Herbal Cure. I contemplated for about 4 hours whether or not to contact him. then something inside of me told me 'Nothing good comes easy'. I then contacted him through his email and told him my problem. He told me all the things I needed to do and also gave me instructions to follow, which i did properly. Just within weeks of drinking and applying the herbal medication he sent to me through dhl delivery service, i started seeing changes, i went to my medical doctor for check-up, i was so happy when the doctor told me i was no more having Genital Herpes Virus, it was all tears of Joy from that moment, People think herpes is really a minor skin irritation herpes has a long term effects on health and if i could ever meet a Genuinely Great Herbal Doctor. I'm so grateful to him. i am completely free from Genital Herpes Virus, i introduced a family friend who have Simplex Herpes virus to him, He called me and told me he was also cure completely. I promised to share my own testimony like that of the lady on the internet. Friends, if you are also struggling with Herpes disease you can as well Contact him via Email:

  3. Thank you sharing your insightfully opinion. Based on my research I have found running is best exercise to stay fit. Do you know benefits of running?

  4. Appreciation is the key to doing more. That is why I have taken some time out to thank someone who cured me of my 5 years of HSV problem. It became a major problem to me as it was affecting my marital life and I was no longer comfortable so I decided to look for a solution and I came across a post of Dr.Godday and how he has been helping people of the same problem I quickly contacted him and told him all I have been facing in my life. He told me how to get his product and how to take it after everything. I found out that all was now okay with me and that my HSV problem was gone. That is why I have come out today to say thank you to Dr.Godday . if you need cure for HIV/AIDS, Herpes, Cancer or Diabetes of all types you can contact his via email: or Whats App no +2349018437588.
