Drive-through testing for COVID-19 antibodies, which started last week on the Big Island, is apparently the first of its kind available in Hawaii.

The presence of antibodies, or proteins that help fight off infections, can be detected with a simple blood test and can determine if an individual previously had COVID-19.

Premier Medical Group and Hawaii County began the antibody testings at a COVID-19 drive-through screening and testing clinic Wednesday in Hilo. The antibody testing took place again Friday in Waimea.

Kaohimanu Dang Akiona, a physician with Premier Medical, said the antibody test is intended for those who had a positive COVID-19 diagnosis, those with close contact with a positive case, and those at higher risk of being exposed, like first responders and other essential workers.

In the coming weeks, Akiona said the goal is to refine the testing and share the results with the larger medical community and state leadership.

We all know its a good idea, she said. I want to give (people) a concrete example of how we did it. I think its harder to ignore the utility of the test if we can show that we did it, that its possible.

COVID-19 wont just go away, said Akiona, who added much remains unknown about the nature of the disease. But antibody tests help officials know how many people have been exposed to the virus so far and is one of the tools that will help the state safely reopen.

Identifying those who test positive for the antibodies also might help in the development of future treatments.

According to Akiona, the antibody tests also are very accurate.

On Wednesday, 38 tests were performed, and although all the results werent available, no positive results had been detected by noon Friday, she said.

We just need to show people it can be done and hope more people can join us and help, she said of the screening and testing efforts.

Additional COVID-19 screenings and tests, as well as the antibody tests, were conducted Saturday at Kamehameha Park in North Kohala. More will be done from 9 a.m.-1 p.m. Monday at the Afook-Chinen Civic Auditorium in Hilo.

There will be a $43 out-of-pocket cost to individuals whose medical insurance will not cover the antibody test.

The standard COVID-19 screening and testing, however, is free, but individuals must meet the criteria established by U.S. Centers for Disease Control and Prevention and the states COVID-19 Response Task Force to be tested.

Clinicians on site will make the determination about who will be tested.

Those who visit the screening sites will be asked to show photo identification, and people should bring their own pens and health insurance cards.

Weve expanded pretty much around the entire island, Garrett Kim, Hawaii Fire Departments representative on the countys COVID-19 task force, said of the drive-through testing clinics. We were concerned we werent getting a good picture of what was really happening in our community.

The drive-through testing sites are a collaboration between the county and other testing providers, including Premier Medical.

Akiona said the clinics have performed about 3,000 tests, but have screened close to 10,000 people since the first clinic was held in late March.

We cant fight it as a task force unless we know where it is, Kim said. This testing will give us insight where it is in our community so we can allocate our resources and mitigate any outbreaks as soon as possible.
