Serology Antibody Testing for COVID-19 in Hawaii
Minit Medical providers can order serology testing for patients through Clinical Laboratories of Hawaii. A patient who is concerned they were exposed to COVID-19 starts with a video visit with one of our providers. The provider will determine if the patient is a candidate for serology testing. Once the provider orders the test, the patient will go to Clinical Laboratories for a blood draw. The serology test does not confirm immunity of COVID-19 at this time, only previous infection. The fee for the Anti-body test through Clinical Labs is $43.00. You should contact your insurance company to determine if the cost if covered.
Effective April 30, 2020, Clinical Laboratories of Hawaii (CLH) will begin offering serologic testing for antibodies to SARS-CoV-2, the virus that causes COVID-19. The test conducted on the Abbott Architect platform is a chemiluminescent microparticle assay (CMIA) that will detect IgG antibodies to SARS-CoV-2 with 99% specificity in serum specimens. These antibodies are specific proteins found in blood and are produced by a person’s immune system as a result of infection. This test has received Emergency use Authorization (EUA) by the Food and Drug Administration (FDA).
Serologic testing alone should NOT be used to diagnose ACTIVE infections by SARS-CoV-2
• A positive IgG antibody result indicates exposure to SARS-CoV-2. The majority of patients with infection have IgG seroconversion after 14 days. A positive serology result does NOT mean the virus is inactive.
• A negative serology result indicates that an individual has no detectable antibodies at the time of testing. This could be due to non-exposure to virus, testing too early in the course of viral infection, or the lack of an adequate immune response (i.e., immunosuppression).
• Insurance coverage is based on determination of medical necessity. Healthcare providers and patients are advised to contact their insurance company directly for coverage eligibility. The cost of the test through Clinical Laboratories of Hawaii is $43.00. If insurance does not cover the test you will receive a bill from Clinical Laboratories of Hawaii.
Serology Testing for COVID-19
CDC has developed a new laboratory test to assist with efforts to determine how much of the U.S. population has been exposed to SARS-CoV-2, the virus that causes COVID-19.
What CDC wants to learn:
The serology test looks for the presence of antibodies, which are specific proteins made in response to infections. Antibodies can be found in the blood and in other tissues of those who are tested after infection. The antibodies detected by this test indicate that a person had an immune response to SARSCoV-2, whether symptoms developed from infection or the infection was asymptomatic.
Antibody test results are important in detecting infections with few or no symptoms.
Currently, CDC’s serologic test is designed and validated for broad-based surveillance and research that will give us information needed to guide the response to the pandemic and protect the public’s health. The test is not currently designed to test individuals who want to know if they have been previously infected with COVID-19.
The results of these studies will allow us to estimate how many people have been infected nationally. The results will also provide information about the percentage of U.S. residents who have not had COVID-19 and are still at risk for infection. This research is designed to help us understand who has been infected with SARS-CoV-2 and determine factors that confer protection against this virus.
