Frequently Asked Questions
Does BioSmart test for the virus that causes Covid-19?
Yes, testing for the SARS-CoV-2 virus that causes Covid-19 is performed in our state of the art laboratory using SAHPRA approved qPCR Covid Tests that detect two different SARS-CoV-2 genes: N1 and N2. There is also an internal control that detects the presence of human RNase P. A positive result means all three of these genes have been detected in the sample.
Why anterior nasal swabs?
Our aim is to make testing more accessible by non-invasive sampling. The sensitivity of anterior nasal swab samples have been extensively validated on our platform following protocols that have been given Emergency Use Access by the CDC (USA).
Why should we get tested?
In order to prevent the spread of the virus mass testing is critical. Many people, especially children, can spread the virus without knowing they are infected. Unfortunately the virus can be deadly for some people including the elderly, and those with diabetes or cardio vascular disease are ecpecially at risk.
Why should we test every week?
When combined with regular hand washing, mask-wearing and social distancing, regular repeat testing can quickly identify those with the virus, preventing
I was exposed to someone who tested positive - when should i test myself?
If you have been exposed to someone with Covid-19 you should assume that you may have been infected. It will typically take 4-6 days for the virus in your system to be detectable, so isolate and arrange to be tested 6 days after you were exposed. Do not test too early because you could get a false negative result.
How do the samples reach the lab?
Samples must be packaged in the sample kit box which is then closed in the biohazard zip-lock bag as instructed. It is important to follow the instructions in the pack closely because samples that are not packaged correctly will be rejected by the lab without refund.
What if I need advice regarding my results?
Our policy regarding the protection of your personal information?
We are fully compliant with the Protection of Personal Information Act (or POPI Act) - which became a legal requirement in June 2020. For more information, please contact us.
What if I have a complaint?
If you have a compliant, please contact us and we will do our best to resolve the issue.
Sample acceptance or rejection?
Samples will be rejected if full payment for the test has not been recieved. On payment, you will recieve a test TOKEN. It is critical that you include the TOKEN number and your details in the document sleeve of the biohazard bag.
What factors can influence the PCR test result?
The PCR test is run on saliva (NOT sputum). The difference between the two is big - sputum being thick and lumpy and is coughed up from your lungs.
Are the tests accurate?
The RT-PCR test is the most accurate way of detecting the virus that causes Covid-19.
What is the difference between an antibody test & the RT-PCR test?
The RT-PCR test will tell you if you are currently infected with the virus that causes Covid-19.
What is the sensitivity & specificity of the COVID-19 RT-PCR test?
The tests performed by the BioSmart lab are approved by SAHPRA.
Sensitivity (clinical) onlow viral load: 94.1%
Sensitivity (clinical) on high viral load: 100%
Specificity (analytical): 100%
What is the turnaround time for travel certificates?
if you test in the morning before 10am, we will send your travel certificate on the same day.
