Our COVID-19  prevalence is low in our county.   We have run around 600 IgG with only 3 positive and they are low positive..   We are  sending out +IgG to outside lab for confirmation. If the serology IgG is low positive on Abbott and neg on Viracor we result the test as indeterminate.
   Our lab team is  doing IgG/IgM serology validations on   our healthcare workers who have +PCR and were symptomatic and we are able to validate IgM and IgG levels  in this population.

We are not sure how useful serology is at this point for asymptomatic HCWs since our area has such a low prevalence.   We plan on continuing serology on all healthcare workers   to hopefully get an idea of prevalence in our workforce and to collect more data on serology testing in select populations.

Our esoteric lab manager has put together some useful information if anyone is interested.  Please email and I’ll send it.  JoAnn

Hello JoAnn

I am in Springfield, MA.  Our parent corporation is holding back on the serology testing due to high false positives when prevalence is fairly low.  Do you know the prevalence of COVID in Tampa?

I would be interested in your results.

Thank you,

We stopped using the test based strategy as all were PCR + for more than 3-4 weeks and infectivity at that point was not clear.     We started IgM/IgG testing in-house last week  and require IgG + in addition to  14 days OOW from onset  of symptoms and 7 days symptom free to RTW. Since last week, we have been drawing   serology on all PCR COVID+ healthcare workers to validate our testing and to assist with RTW decisions.

We also started drawing serology on HCW  with classic COVID-19 symptoms in addition to the PCR.     Yesterday we had a positive IgM on a nurse  with classic COVID-19 symptoms ( cough, SOB, fever, loss of smell/taste) but had two previous negative PCR from our screening clinic.

Today, we opened up IgG testing to all HCWs in the organizations  and offer 100 appts per day in our TMH clinic.   We hope this testing will allow us to identify how many of our HCW may have had asymptomatic infection and how many are susceptible.   We reiterate to our HCWs that a positive IgG does not indicate the amount or duration of immunity or if they are protected from reinfection.

Our Infectious Disease physicians plan to conduct a retrospective study on IgG testing of healthcare workers once we have a large enough sample.   We have already scheduled over 2500 for IgG testing and are hoping for at least 5,000 by July.  We included data points such as history of exposure, perform aerosolizing procedures, work in high risk unit,  history of symptoms but never tested, and random selection of HCWs.

Will be happy to share results with this group.

Hi Melanie. Thanks for the feedback at this strange time. I totally agree. Our institution after further discussion with myself, ID and Medical Director of Lab were able to convince our Quality Medical Officer that we did not want to use the PCR method for the reasons mention. Instead he will wait until we have AB (IgG) testing on asymptomatic HCWs since the rational is easier to explain and better at determine past exposure and immunological response. But again we are not sure of neutralization of infection and future protection. <https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>

Bill, We are hearing a lot of institutions grappling with this and the desire to test asymptomatic employees is understandable. It’s prompted by an awareness of asymptomatic spread.<https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>
I would caution you to consider test frequency. A negative PCR test today does not ensure the person won’t be positive in another 2 days, which begs the question of why start doing it unless you plan to continue testing every few days.<https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>

If you find a positive PCR in an asymptomatic person, I think you are obligated to use the test-based strategy for RTW. The non-test-based strategy is to return them after 7 days from symptom onset. Pretty hard to calculate if there are no symptoms!<https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>

Thanks for opening up on this discussion. I agree with many of these point. We are about ready to start Ab testing HCWs in our institution but we do not know how yet to interpret the testing. We hope like in other viral IgG responses there will be protection. <https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>

Additionally my institution will start test asymptomatic HCWs via PCR (since it is readily available now). How would one dealing with asymptomatic PositivePCR COVID-19. Do you take then off work/isolate for stand 7 days (CDC guideline) or let them work with masks?<https://urldefense.proofpoint.com/v2/url?u=https-3A__health.usnews.com_best-2Dhospitals_area_fl_tampa-2Dgeneral-2Dhospital-2D6391060&d=DwMFaQ&c=WxSiHUljzaZa6AO7gfNF1nsjLMo-cFTcJAt_xkKy0sg&r=i5vd-CpfKk0L54XwZivpPw&m=DALhBkYGZ2FEBFWUQmjUrVvdVd2hELjHk7QOJPZnQS4&s=fEuy-_ERmKGE-1Eq2ID7zO7VcJXay3UC7disN8qP3V8&e=>
