For two straight years and counting, the COVID-19 pandemic continues to steal the limelight from any other global issues. Though we can see a significant improvement in curbing the virus transmission through vaccines and booster shots, COVID-19 tests haven’t lost their appeal to the general public and the medical field.
Rapid antigen tests are growing in popularity even if we think the pandemic is near its twilight. This is because we need to be prepared to protect ourselves from the virus whether you had COVID-19 in the past or will have another soon.
But how reliable are COVID-19 tests?
COVID-19 testing kits are a popular way to determine one's risk level for the virus and get a diagnosis. They are available for purchase online, in pharmacies and other stores, and more people are using them every day. However, with the abundance of tests, how do rapid antigen tests compare with those in the lab or doctor’s clinic?
In the lab, your doctor will collect a PCR sample by inserting a swab into your nostril (thus, the swab test). This takes back the cells from your nose. Other times, a swab test is done through a saliva test. Either way, a PCR test examines the genetic material or the presence of the virus in your system.
The results from PCR tests may take longer than a rapid antigen test. However, if the test is performed by a health expert, the results are accurate.
COVID-19 rapid tests produce results faster, as they can determine the presence of COVID-19 within minutes. Still, the test is performed on a single drop of blood, saliva or nasal swab for it to be detected.
If you are having symptoms of COVID-19, you can perform a test at home if you need instant results. Whilst they may offer quick results, sometimes they miss. This is why they are less than accurate compared to PCR tests.
However, rapid antigen tests can be a good way to test for COVID-19 when conducted with proper timing and strict adherence to the testing kit’s instructions. Sometimes, whilst used alone, the probability of human error is high. But the best time to get accurate information is during the day you feel you have the symptoms.
You may be infected with the virus, but your rapid test says you’re negative—this means the test yielded a false-negative result. False-negative serves as a precaution because one may think it is safe to engage socially. On the other hand, false-positive results can be as equally dangerous as false-negative because they will put a lot of stress on the affected person, leading them to make crucial decisions that impact their productivity in daily living.
For accuracy, many healthcare providers order COVID-19 lab tests or imaging scans to confirm a diagnosis. These tests help rule out other health issues or determine the severity of your condition. Tests can also show if your condition is improving or worsening. Other tests can detect or rule out conditions that may mimic COVID-19.
Whilst we have a better perception of the usefulness of both tests, you can use any of the tests according to your unique circumstance.
PCR tests are considered the gold standard for COVID-19 tests. Though results may be delayed compared to rapid antigen tests, these tests are usually done in the lab by health practitioners who are fully equipped to determine the accuracy of the results.
If you are experiencing any of these symptoms, you should seek a COVID-19 test:
Using rapid antigen to detect COVID-19 at home is still your best shot if you want quick results. If you have the symptoms, especially, or you know you have interacted with someone with COVID infection, at-home rapid antigen tests will give you a good sense of whether you are infected or not, so you know what to do next.
Yes, rapid antigen tests are reliable. Although not 100%, you can still bank on 90% accuracy rather than having no tests at all and relying on hunches. Additionally, you can always rely on PCR tests if you’re unsure of your rapid test results.
Given that you purchase a rapid antigen testing kit to be brought at home, following the manufacturer’s instructions is essential before using the test.
To use a COVID-19 test at home, you need to prepare your supplies. These include a COVID-19 test kit, a flat surface where you can swab a person’s body and a clean, dry container where you can put the swabs.
You should also observe these simple rules:
There’s no right or wrong answer to which is the better at-home COVID-19 test. Ideally, at-home tests are not literally conducted ‘at home’. They can be used ‘anywhere’. Lastly, at-home rapid COVID test kits offer results in minutes and can be bought over the counter.
As the surge of COVID-19 infection may have waned, the presence of variants, such as Delta and Omicron, continue to scare people around the world. Whilst grappling for COVID-19 tests, you may be one of those to ask where to buy rapid antigen test kits.
Many people prefer at-home rapid antigen tests in place of laboratory-based COVID testing due to their convenience. In the hopes to alleviate their concern if infected with the virus, people have the comfort to purchase rapid antigen test kits over the counter or online.
