PCR vs Rapid Antibody COVID-19 Testing

PCR vs Rapid Antibody Covid-19 Testing - Rapid Connect Medical

After the COVID-19 (Coronavirus Disease of 2019) evolved and the World Health Organization (WHO) declared it a global pandemic, there was an urgent need for diagnostic testing. Most countries started testing for the virus when the infection was at an early stage to identify and control it within a particular region. 

Reverse Transcription-Polymerase Chain Reaction test 

The reverse transcription-polymerase chain reaction (RT-PCR) tests were the first to be administered after getting an official recommendation from reliable health agencies such as WHO, CDC, and the European Centre for Disease Prevention and Control (ECDC). This technique involves the use of molecular tests, which detect the ribonucleic acid (RNA) of the SARS-CoV-2 virus. 

For you to administer a (RT-PCR) test, you will need to be a highly-skilled technologist to perform the diagnostics. Since you will be using multiple reagents, the test is supposed to be done in a well-equipped laboratory. With this technique, at best, it would take you about four hours to get your results.  On the other hand, it would take days if the samples were sent to an offsite lab. 

Due to the urgent need to test more people in a day, the (RT-PCR) tests proved to be unreliable for this goal.  The use of COVID-19 test kits in the US came into the picture after the FDA invoked emergency use authorizations (EUA). This decision triggered an unprecedented scramble among medical manufacturers to develop reliable coronavirus antibody test kits. 

Rapid Antibody Test

COVID-19 test kits are available in two forms: direct SARS-CoV-2 antigen and indirect antibody detection. The chromatographic immunoassays are considered to be complementary to molecular genetic assays. The serology or antibody tests are can detect antibodies to the virus in less than an hour if you factor in the preparation process.

The median time to a result is low for a COVID-19 antibody test kit when compared to the standard lab RT-PCR test. The switch to reliable coronavirus antibody test kits saw a reduction in the average time a patient would spend in a COVID-19 ‘holding ward’ before being discharged or making progress with treatment. It also caused a reduction in the use of single-occupancy isolation rooms by more than 9%. 

According to ECDC, the performance of rapid diagnostic tests may vary compared to the manufacturer’s performance study. In reality, rapid tests are often less sensitive and accurate compared to laboratory-performed diagnostic tests.  In such a case, the diagnostic performance of rapid tests for COVID-19 will require clinical validation and this is the reason why they are usually compared and combined with RT-PCR test results and clinical observations.

The performance of a rapid COVID-19 antibody test kit is usually determined by the accuracy, sensitivity, and specificity percentages- the higher the number, the more accurate your results will be. Rapid Connect Medical is an exclusive distributor of Coronavirus (SARS-CoV-2) IgM/IgG rapid Test Kits with percentage sensitivity, specificity, and accuracy of 90.44%, 97.25%, and 95.72%, respectively. 

Different from the standard RT-PCR lab tests, rapid COVID-19 diagnostic tests are done on patients that are suspected to have symptoms of the virus. These are usually people under quarantine. Diagnostic tests for COVID-19 antibodies can also be administered on people without symptoms; especially those who have had close contact with infected people. 

Rapid COVID-19 Antibody Test Kit Features:

  • The kits are easy to use and require no special equipment or Intuitive visual interpretation to administer the test. 
  • It can be used to detect IgM and IgG antibodies against the COVID-19 virus at different infection stages.
  • The tests executed with these kits are fast and effective since sampling is by fingertip blood. The results are visible in two to ten minutes and remain valid within 15 minutes as opposed to days or weeks for standard RT-PCR lab tests.
  • The IgG and IgM results obtained from these kits are accurate since they can be validated using PCR and CT test results.
  • The kits can easily detect antibodies three days after the infection (potentially before symptoms begin). 
  • Healthcare personnel can administer diagnostic tests for COVID-19 antibodies with ease – only a blood sample is required.
  • All-in-one kit contains all required components.
  • The kits are cost-effective.

Limitations of COVID-19 IgM/IgG Rapid Test Kit

  • The qualitative COVID-19 Rapid Test may not be able to determine the quantitative value or rate of change in antibodies present in a patient.
  • The sample taken for the quality active rapid chromatographic immuno assay requires the use of human serum, plasma, or whole blood samples only. 
  • In the early stage of the infections, the concentration of the IgM may be below detectable levels.
  • A COVID-19 IgM or IgG Rapid test will not detect the COVID-19 virus, but it will reveal the presence of antibodies produced by infected or exposed human body to fight the virus.
  • A negative result is not a guarantee that the patient does not have COVID-19 infection.
  • Improper handling and storage of the Coronavirus Antibody Testing Kit can lead to incorrect results.

Generally, a COVID-19 IgM/IgG antibody rapid test has proved to be useful in providing information on the SARS-CoV-2 infection status in a person. Reliable coronavirus antibody test kits offer a more affordable and convenient option than on-site diagnostic laboratory testing. 

Get your robust, easy to use, and inexpensive rapid COVID-19 antibody test kit order delivered today by Rapid Connect Medical.

The rapid COVID-19 antibody test kits you will find on the market are designed to detect SARS-CoV-2-specific antibodies. The ones distributed by Rapid Connect Medical are FDA research approved and validated by a comprehensive clinical study.  The CDC testing standards for laboratories were strictly followed during the clinical trials for our antibody test kit.  This is a serology elisa based test for SARS-CoV-2 antibodies in serum or plasma components of blood. Information on the collection data and validation of lab samples can be found here for review.

The sampling done with the rapid COVID-19 antibody test kit cassette using lateral flow from Rapid Connect Medical will give you the IgG and IgM detectable diagnostics results from between two and ten minutes. It can be used for reference in combination with the results from an RT-PCR (reverse transcriptase-polymerase chain reaction) test. This positive or negative result can be as soon as 3 days after exposure to COVID-19 (sometimes before the onset of symptoms occur).  If you do test positive, you should seek care from your doctor for treatment and continue to test for IgG antibodies daily until you are cleared to leave quarantine. The sensitivity, specificity, and accuracy or our antibody test kit is very high.  This testing method for the public gives real time results.

The kits used for diagnostic tests for COVID-19 antibodies are usually designed for research use or qualitative detection of coronavirus, and not home use. Also, they can only be used to test the presence of IgG and IgM antibodies against SARS-CoV-2. Since they are aiding tools to RT-PCR or CT scanning, a clinical diagnosis of COVID-19 should be done by a healthcare professional or physician.
