The Efficacy of COVID-19 Antibody Test Kits

The Efficacy of COVID-19 Antibody Test Kits - Rapid Connect Medical

As the demand for COVID 19 antibody test kits increases, you will find numerous solutions present in the market. The challenge that most people go through is determining which ones works best. One of the best ways to determine the performance of a coronavirus antibody testing kit is to check for the percentage in accuracy, sensitivity, and specificity.


Accuracy in the diagnostic tests for COVID-19 antibodies means that the provided results are correct values. 


A high sensitivity percent agreement or coincidence diagnostic tests for COVID-19 antibodies shows that the device can detect even the lowest strain of the virus. 


A high specificity percent agreement or coincidence diagnostic tests for COVID-19 antibodies means that the device can produce the expected results. For example, in a test for a population of 100 Covid-19 patients, if a coronavirus antibody testing kit confirms finds the same results, then the device has a specificity of 100%. The test must be specific enough not to yield false-positive or false-negative results. 

The COVID-19 antibody test kits distributed by Rapid Connect Medical come with an accuracy, specificity, and sensitivity of 98.23%, 97.50%, and 98.88% respectively. These are results of IgM and IgG tests combined against reference standards in the overall study population.  The IgM and IgG test are usually done separately and later combined to get an overall agreement rate. 

A Comparative Study 

For one to test the relative sensitivity and specificity of the COVID-19 IgG-IgM antibody test kit, a comparative study must be conducted. The study uses blood samples from PCR-confirmed COVID-19-infected patients or convalescents, and healthy individuals (negative controls). In this exercise, samples are collected anonymously from multiple hospital laboratories per the local ethical guidelines.

Besides confirming a rapid COVID-19 antibody test kit results with that of a PCR test, the results must also be validated by clinical observation, analysis, or diagnostics. It is important to compare the in vitro diagnostic reagents used in the test with the clinical diagnostic criteria of new coronavirus pneumonia to verify the clinical performance of the kit.

The results from the diagnostic tests for COVID-19 antibodies should yield a high positive predictive value for the blood samples of COVID-19-infected patients and a high negative predictive value for the samples of healthy individuals. 

A COVID-19 antibody test kit with a high negative predictive value is of great importance. These results will help in detecting past infections and immunity to the disease. Such tests used together with clinical cases and PCR-positivity tests will help in the development of risk-based approaches for restoring the economic and social activities in a community. 

Reliable Coronavirus Antibody Test Kits go through a preliminary evaluation to confirm their clinical performance, which determines if they can meet the emergency use requirements of the pandemic. 

Factors that may affect the results of a Rapid Covid-19 Antibody Test Kit:

Cross Reactivity: some Coronavirus (SARS-CoV-2) IgM/IgG rapid Test Kits can easily cross-react with positive samples of antibodies for viruses such as Influenza (A &B), Parainfluenza, Pneumoniae (Chlamydia & Mycoplasma), HIV, Measles, Chicken Pox-Zoster, Hepatitis (B&C), Mumps, Adenovirus, Treponema Pallidum, Enterovirus 71, Cytomegalovirus, Respiratory Syncytial, and other common coronavirus strains. 

Sample Collection: Poor collection of serum, plasma, and whole blood specimens can yield false results rendering the kit not fit for emergency use requirements of the pandemic.

Handling and Storage of Specimen: Poor handling and storage of the, and whole blood specimens can also contribute to the performance of the rapid COVID-19 antibody test kit. For instance, plasma and serum specimens to be stored for up 3 days must be kept at a temperature of 35.6-46.4°F  (2-8℃).

Testing Environment: as per the device instructions, Diagnostic Tests for Covid-19 Antibodies using Covid-19 Antibody test kits should be done in a hospital laboratory or approved laboratories under room temperature (59-86°F or -15- 30℃)

Low Antibody Count: some people may produce undetectable amounts of antibodies against the novel Coronavirus (SARS-CoV-2). Antibodies levels do wane with time, an event that can lead to false-negative results. 

Faulty Kit: These are common since most manufacturers are working extra had to meet the market demand. 


As you have noticed, the performance of a coronavirus antibody testing kit relies on several factors that must be kept at optimum and required levels to yield correct results. Most experts in the medical field will always advise against test kits that provide false-negative results.  The efficacy of a COVID-19 antibody test kit relies on the relative sensitivity, specificity, and accuracy of the devices.

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.

An antibody detection test cassette contains antigens from SARS-CoV-2 combined with gold nanoparticles. The device has two wells (one for specimen and one buffer) and a control region on the upper end.  Two types of antibodies are of great importance in diagnostic tests for COVID-19 antibodies: Immunoglobulin M (IgM) and Immunoglobulin G (IgG). 

The importance of the gold nanoparticles in the detection test cassette is to create a colored line in the control region.  Antigens targeting a specific antibody are located in their respective regions on the nitrocellulose membrane of the test cassette. The IgG and IgM regions are coated with anti-human antibodies for each.
