13 hours ago More than 300,000 Positive Test Results. Despite the impact we’ve had together, we see the response to this pandemic continuing to evolve as we enter its third year. We are thankful that … >> Go To The Portal
Accuracy: The BinaxNOW test correctly gave a positive result 84.6% of the time compared to PCR. In the same study, the test correctly gave a negative result 98.5% of the time. Availability: The BinaxNOW test costs $24 for two tests, which are meant to be used on the same person within three days (serial testing).
This COVID-19 test detects certain proteins in the virus. Using a long nasal swab to get a fluid sample, some antigen tests can produce results in minutes. Others may be sent to a lab for analysis.
A faint line also can mean the tester didnt swab well enough to provide a good test sample. A brighter line indicates the patient has more virus in their body and is likely to be sicker and more infectious.
“PCR would be chosen where there is a low likelihood of having the virus, but we want to be certain the patient doesn't have it. Antigen would be chosen if there is a high probability the patient has the virus (i.e. is experiencing symptoms), and we need to screen the patient as positive or negative,” Heather said.
However, at-home COVID-19 antigen tests are generally expected to detect the SARS-CoV-2 virus at least 80% of the time when someone is infected.
PCR tests are more accurate than antigen tests. "PCR tests are the gold standard for detecting SARS-CoV-2," says Dr. Broadhurst. "It is the most accurate testing modality that we have.
It's possible to have a positive test result even if you never had any symptoms of COVID-19 . False-positive test results can occur. It may be that the test detected antibodies to a coronavirus closely related to the COVID-19 virus or that the test quality was flawed.
A false-positive antigen test result means that the test says the person has COVID-19 but they are actually do not have COVID-19.
The investigators also point out that false-positives are possible due to administering the test too early or late in the infectious stage, or from incorrectly performing the self-test.
“PCR tests are more reliable and accurate due to testing the specific genetic material of the virus, eliminating the interference from other viruses,” said Heather Seyko, a Laboratory Services manager for OSF HealthCare.
Some people with mild infections may test negative on an antigen test, but positive on a PCR test. This would mean that they have COVID, but don't have enough virus to turn an antigen test positive.
A single antigen test may only be able to correctly identify the virus 60% of the time in patients who have the omicron variant and who display symptoms of the disease, Tim Stenzel, director of the Food and Drug Administration's Office of In Vitro Diagnostics and Radiological Health, said during a Wednesday meetin.

Antigen tests typically give results in just 15 minutes, can be done at home by yourself, and are much less expensive than PCR tests.
Positive test results using a viral test (NAAT or antigen) in persons with signs or symptoms consistent with COVID-19 indicate that the person has COVID-19, independent of vaccination status of the person.
The rapid antigen tests that most people are using in the U.S. are specifically designed for nasal swabs.

Summit Medical Group offers a secure, convenient online patient portal that allows the user to submit appointment requests, prescription renewal requests, payment for services rendered and to complete registration forms. Log in now.
As of September 1, 2020 Summit Medical Group has a new and improved patient portal. This portal will allow patients to request and view appointments, send messages or refill requests and view test results and billing online without having to schedule an appoint ment or wait on the phone. After September 1, Summit will no longer update patient records on the ‘FollowMyHealth’ portal, but patients can still access their pre-September 2020 personal medical history by visiting the Follow My Health website. Click the button below that corresponds with your current need:
The patient portal may be used to request an appointment, request medication refills, view health records, and to view lab reports.
The typical new patient visit is a consultation in which your new provider will take the time to get to know you personally as well as your medical history. Devoting this extra time at your initial visit allows us to gain a solid foundation of your health information that will result in us providing you with the highest quality care. After your initial consultation, we will together determine when lab work, additional testing, and/or a physical are needed.
These amounts are payable to Brio Internal Medicine. The balance due is payable in full within 10 days of receipt of the monthly billing statement. If you have questions about your account please call 864-603-5600.
You have a sinus infection, the flu, etc. and need to be seen as soon as possible.
The Annual Wellness Visit is not the same thing as what many people often refer to as their yearly physical exam. Medicare is very specific about what the "Annual Wellness Visit" includes and excludes.
Brio is now accepting new patients! Call or email us to set up your initial consultation where one of our providers will review your medical history and any concerns you may have to ensure that we provide you with the care that you need. Also, feel free to download, print, and complete our New Patient Forms to minimize your wait.
