Rapid Antigen Testing (KDHE Testing Program) Q&A
The BinaxNOW™ COVID–19 Ag Card is a rapid antigen test for detecting active infections of COVID-19. The test has received U.S. Food and Drug Administration (FDA) Emergency Use Authorization (EUA). It is a cost-effective, high performing test designed for decentralized testing.
It is a simple test procedure using a direct nasal swab. Trained staff administering the test may visually read results in 15 minutes without the use of additional equipment.
Watch a video of how this test is administered.
The BinaxNOW™ COVID-19 Ag Card is a reliable, highly portable tool for detecting active coronavirus infections. BinaxNOW uses proven Abbott lateral flow technology, used in a number of rapid tests including strep, flu and legionella – as well as HIV and malaria.
In data submitted to the FDA from a clinical study conducted by Abbott with several leading U.S. research universities, the BinaxNOW COVID-19 Ag Card demonstrated sensitivity of 84.6% (positive percent agreement) for the entire study population, 95.6% for those with PCR cycle threshold (Ct) of <33 and specificity of 98.5% (negative percent agreement) in direct nasal swabs from individuals suspected of COVID-19 by their healthcare provider within the first 7 days of symptom onset.
Rapid antigen tests are not as specific and often require confirmatory testing to rule out a false positive or false negative. They are best used in an outbreak setting or when individuals are being tested frequently (i.e. every day or every other day).
Saliva PCR tests are used to confirm a positive antigen test result. Health officials consider a PCR test the ‘gold standard’ in detecting COVID-19 infection.
The individual will be required to spit into a tube in order to provide the sample. Additionally, the individual being tested must not eat, drink (other than water), or brush their teeth for 30 minutes prior to the test. School health or designated staff will plan testing at a time that accommodates these instructions.
The samples will ONLY be used to identify the presence of the virus that causes COVID-19, and will not be analyzed for other purposes.
Watch this video about the process for providing a saliva sample for a PCR test:
PCR test results are generally available within 48 hours, depending on timely delivery of samples to the lab.
The lab may contact you when results are available using the phone number you provide when registering the test. You may go to the lab’s website (https://crlclear.com/login) and log in using the phone number you provided and either your or your student's birthday to retrieve your test results.
LDCPH will receive test results and will share them with Lawrence Public Schools.
In the event of a positive PCR test result, the individual is required to isolate for 10 days following the positive test (if feeling well). If sick, even with mild symptoms, they are required to isolate 10 days following the start date of the symptoms. They may return to regular activities at the end of the isolation period. Additionally, they must be fever-free and feeling well for 72 hours to return to school and participation in school activities.
Parents/guardians, students age 18+, or staff members may provide school health or designated staff PCR or antigen test results from a testing center (e.g., CVS, Walgreens, pharmacy). The district will not accept at-home test kits for students/staff during the quarantine period.
If an individual has tested positive for COVID-19 in the past six months, they are exempt from quarantine. They must provide the positive antigen or PCR test or a note from the local health department to school health or designated staff as evidence. Additionally, they must remain symptom-free.
Please direct questions to the school nurse, your primary healthcare provider, or the health department.
