OJABIO SARS-CoV-2 Antigen Test Kit

Collodial Gold Method | 15 Minutes Rapid Results

Antigen testing looks for the presence of the SARS-CoV-2 virus in the body. In an antigen test, a Cheek Swab is done and the sample is tested to detect fragments of proteins which are found on or within the SARS-CoV-2 virus. Results of the test are easily interpreted.

Product Benefits

Help to avoid “false negative” and missed diagnosis

Antibody is the product of humerol immune response after infection with the virus. In general, IgM antibodies appear in the middle to late stages of the infection. Titers have a continuous process of increase and staying in circulation for a longer period of time. Testing for specific antibodies can determine whether a patient has “recently or previously been infected with COVID-19”.

Complementary nucleic acid testing helps to avoid “false negatives”

Applicable to medical institution labs at all levels

Easy operation, no lab or instruments required which relieves the pressure on professional clinical labs testing.

Release medical resources

Results available within 10 mins. This helps patients get treatment as early as possible, and shorten the diseases course thereby easing pressure on medical resources

Simple specimen collection

Can be tested with specimen whole blood, serum or plasma. Easy to operate, removing the need to take specimens from oropharynx or nasopharynx.

Frequently Asked Questions

The New Standards of Healthcare

  • An antibody is a specialised protein made by the body in response to infection.  When a virus infects a person’s cells, the human immune system develops targeted antibodies to fight and eliminate the virus from the body.  These antibodies circulate in the blood and can be tested for.   This is known as a serological test.

  • This test is suitable for detection of antibodies against SARS-CoV-2, in human serum, whole blood or finger prick samples.  It can detect specific IgM and/or IgG antibodies that develop in response to an infection with SARS-CoV-2.

  • If a person has specific antibodies to SARS-CoV-2 in their blood, it suggests they have had infection with SARS-CoV-2.  They may or may not have had symptoms, and they may or may not have developed the disease known as COVID-19.

  • There is a lag time between infection and the production of IgM and IgG antibodies.  This means that whilst a positive antibody test can tell us if a person has been exposed to SARS-CoV-2, it can’t tell us if that person is currently or recently infectious.

  • Graph 1 shows the typical time it takes for the immune system to develop a response to infection with SARS-CoV-2 and at which timepoint the IgM and IgG antibodies become detectable.   It’s important that tests kits are readily available for use and that results are interpreted by a professional who understands the timeframes of the immune system response.

  • When combined with the clinical picture, a positive test can aide diagnosis and subsequent management.

  • The antibody rapid detection test is an important tool for clinical assessment as it can quickly determine whether someone has had infection with SARS-CoV-2.

  • Point-of-care serology tests are a useful supplement to virus culture testing methods (like PCR and nucleic acid detection testing), which can take several hours and complex laboratory resources to generate results.

  • Antibody rapid detection tests help us estimate what proportion of the population have antibodies against SARS-CoV-2, and therefore may have immunity to repeat infection.

  • This can help manage the epidemic and assist planning for returning to work and resuming normal activities.

1. Preparing

a) The specimens to be tested and the required reagents shall be removed from the storage condition and be balanced to room temperature;

b) The kit shall be removed from the packaging bag and placed flat on a dry bench.

2. Testing

a) Add specimen Serum/Plasma: The volume of one drop of the specimen dripping from the dropper we supplied is 10 μL. Take 10 μL of serum or plasma into sample well (S), and then add vertically 2 drops (about 100 μL) of specimen diluent. Whole blood: The volume of one drop of the specimen dripping from the dropper we supplied is 10 μL. Take 20 μL of whole blood to sample well(S), and then add vertically 2 drops (about 100 μL) of specimen diluent.

b) The positive specimens can be detected within 10 minutes after sample addition. Relevant verification shows that the observation of the test results will be affected if the reaction time were exceed 15 minutes (record time after sample addition), so it is recommended to read and record the test results within 10 minutes.


It is positive for both IgG and IgM antibodies against the 2019-nCoV if three lines appear. One colored line should be in the control line region (C), and another two should appear in IgG test line region and IgM test line region.

NOTE: The intensity of the color in the test line regions will vary depending on the antibodies against the 2019-nCoV presented in the specimen. Therefore, any shade of color in the test line region should be considered positive.


It is positive for IgM antibodies against the 2019-nCoV if two lines appear. One colored line should be in the control line region (C), and another one appears in the IgM test line region.


It is positive for IgG antibodies against the 2019-nCoV if two lines appear. One colored line should be in the control line region (C), and another one appears in the IgG test line region.


One colored line appears in the control region (C). No apparent colored line appears in the IgG or IgM test region (T).


Control line fails to appear. Insufficient sample volumes or incorrect procedures are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test card. If the problem persists, the test kit should be discontinued of using immediately and your local distributor should be contacted.


This offer is aimed exclusively at commercial customers with appropriate specialist staff. These include: doctors, outpatient and inpatient facilities in the healthcare sector, wholesale and pharmacies, health authorities of the federal, state, communal and community associations, blood donation services, pharmaceutical companies, counseling and test facilities for particularly vulnerable groups of people.

This product is intended for professional use and not for home use. Results from antibody testing are presumptive and should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection status.

A negative result may appear and not correlate with symptoms. A medical professional is required to consider various factors, including confirmation testing, when receiving a presumptive result.
