We are at a critical point with COVID-19 in Oklahoma right now. The hospitals are overwhelmed. It’s bad. It’s really bad. COVID-19 is everywhere. Please stay safe.
I want to talk about testing. There seems to be a lot of confusion about it. So I want everyone to understand how testing works and when to use it.
First: people with COVID-19 can have no symptoms but can be highly contagious. Research suggests that younger people have a quicker incubation period, but we don't really know.
So what should you do, if you are concerned your child has had a “close contact” exposure? That means that you have been within 6 feet, without a mask, for greater than 15 minutes with someone who has a positive test. The 15 minutes means you have to count all the people who have possibly exposed you within a 24 hour period.
PCR
This is the gold standard. It is the most sensitive. You can get this at any point if you are having symptoms. If you have been exposed but have no symptoms, testing around day 4-7 (day 7 is ideal), can help you to know if you’re infected.
OU and IMMY labs offer free testing. You have to make an appointment with them. The testing is drive-thru. Results are generally available within 24 hours. These are free options, but the appointments fill up FAST right now.

You can also do testing through many pharmacy chains in the city. They will file your insurance. They require you to do the swab yourself. This means doing the “brain biopsy” on your own. This can be very challenging as a parent, and if you don’t do the swab correctly, your results may not be good. But if you feel confident that you can do the swab, they are a good resource.
I can do nasal swab, PCR testing through DLO at my office too. Results are generally taking 48 hours. This can change quickly though.
Yale developed a PCR spit test that, in their research, is as good as a nose swab. In Oklahoma, we have a lab that is offering this test.

This company does not file insurance, so you have to purchase the kit and then send it to them. They do send you all the information you need to file your own insurance to get reimbursed. They currently have a very fast turn-around (less than 24 hours), and will allow you to drop off the test at their lab in OKC for faster results. I realize that the nasal swabs can be a huge challenge for my patients with issues such as anxiety or ASD. I have a few of this company’s test kits at my office if you would like to purchase one to have immediately and to avoid a nasal swab.
ANTIGEN
These are rapid tests. Just like a flu/RSV/Strep test. We do have these in the office. We have to swab both sides of the nose. It’s not a deep, back of the throat test, but it’s not comfortable. Your child should have symptoms for at least 48 hours before you consider a rapid test. And, if that test is negative, it DOES NOT rule out COVID-19. So again, rapid tests are good if they are positive. Negative antigen tests are not reliable. A PCR test should be done on a child with a negative antigen test with symptoms consistent with COVID-19 or if a child has had a close exposure.
ANTIBODY
Antibodies against COVID-19 take time to develop. Generally speaking, initial antibodies are not going to show up until 2 weeks into illness (this includes the ~5 day incubation period that is before the symptoms show up). This means that antibody testing is not a useful test in early illness, but may be helpful in late illness. There is a child-specific illness, called MIS-C. This seems to be a late immune system response to the virus. Most children have recovered from the first part of the illness. So this disease appears to be a weird auto-immune problem. Antibody testing can be helpful in this case. Many children have no symptoms of COVID-19. So knowing a child has antibodies to the virus can help to diagnose MIS-C.
RETURN TO WORK/SCHOOL AFTER A POSTIVE TEST
A person with COVID-19 positive testing should not have another PCR test for 90 days after their initial test. It may be positive but unless they have true symptoms of COVID-19, it is HIGHLY unlikely they are infectious. However, a PCR may still be positive. People who have recovered from COVID-19 may be PCR positive in the first 90 days. Employers/schools should not use PCR testing in a person who has recovered from COVID-19 until that person is greater than 90 days from their initial positive test unless that person has symptoms.
QUARANTINE
If you have a positive test, you must quarantine for 10 days after that test. Your family needs to quarantine for 14 days from the positive test or 10 days from their own positive tests. You cannot “test” out of quarantine. A negative test of any kind does not mean you are not infected. This is the hardest part of quarantine. I wish I could say otherwise, but it’s a hard reality right now.
Please take care of yourself. Please protect older family members. They are the most likely to have severe disease, and I am very worried that they won’t have access to a hospital bed if they need it. I realize this has been very confusing for all of us. I’m here to answer your questions. Please contact me if you are unsure.
I’m worried about all of us. I appreciate that you trust me with your children. I have personally spent thousands of dollars in protective equipment/PPE to make sure my office is a safe place for your family. I love seeing your kids. They bring me so much joy. I need to see them become happy and healthy adults.
