COVID-19 “Coronavirus” IgG/IgM Rapid Test Kit
Fast Step, The ‘ONLY’ EUA POC/CLIA Waived COVID19 Antibody test
POC authorization, what does that mean?
This test can be performed and results within 15 mins. Our POC authorized finger stick blood samples can be tested in point of care settings. For example Urgent care centers, doctor’s offices, walk-in clinics, drug and alcohol rehabs, detox, hospitals emergency rooms.
What is Coronavirus?
Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats.
The two highly pathogenic viruses, SARS-CoV and MERS-CoV, cause a severe respiratory syndrome in humans, and the other four human coronaviruses (HCoV-NL63, HCoV-229E, HCoV-OC43, and HKU1) induce only mild upper respiratory diseases in immunocompetent hosts, although some of them can cause severe infections in infants, young children, and elderly individuals.
What Does the COVID-19 IgG/IgM Rapid Serology Test Device Detect?
The COVID-19 IgG/IgM Rapid Serology Test Device is an in vitro immunoassay for the direct and qualitative detection of anti-SARS-CoV-s IgM and anti-SARS-CoV-2 IgG in human whole blood, serum, or plasma as an aid in the diagnosis of primary and second SARS-COV-2 infections.

Level: Laboratory Update
FDA Clarifies CLIA-waived Status for Point-of-Care SARS-CoV-2 Tests under Emergency Use Authorizations
The U.S. Food and Drug Administration (FDA) recently clarified that, when it grants an Emergency Use Authorization (EUA) for a point-of-care test, that test is deemed to be CLIA-waived. For the duration of the national emergency declaration for COVID-19, such tests can be performed in any patient care setting that operates under a CLIA Certificate of Waiver or Certificate of Compliance/Certificate of Accreditation.
In addition, FDA clarified that tests for SARS-CoV-2 that are offered prior to or without an EUA have not been reviewed by FDA, are not FDA authorized, and have not received a CLIA categorizationexternal icon. Thus, those tests are considered high complexity by default until they receive an EUA or other FDA approval that indicates they may be performed as moderate complexity or waived tests.
For more information, visit this FDA Web pageexternal icon, navigate to the section titled “General FAQs,” and view the first two questions and their corresponding answers.

Covid-19 IgG/IgM Rapid Serology Test Instructions for Use
- Remove the test cassette from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the assay is performed within one hour.
- Place the test device on a clean and level surface.
- (For Whole Blood Specimen): Hold the 5 μL mini plastic dropper vertically and transfer 1 drop of whole blood (about 10 μL) to the specimen well(S) of the test device, then add 2 drops (about 80 μL) of sample buffer to the buffer well (B) immediately. Avoid air bubbles.(For Serum or Plasma Specimens): With a 5 μL mini plastic dropper provided, draw serum/plasma specimen to exceed the specimen line as showed in the following image and then transfer drawn serum/plasma specimen into the sample well (S). Then add 2 drops (about 80 μL) of sample buffer to the buffer well (B) immediately. Avoid air bubbles.
- Wait for the colored line(s) to appear. After 2 minutes, if the red color has not moved across the test window or if blood is still present in the specimen well (S), add 1 additional drop of the sample buffer to the buffer well (B).
- The result should be read in 10 minutes. Positive results may be visible as soon as 2 minutes. Do not interpret the result after 15 minutes.
Clinical Evaluation:
For IgM detection:
| Method | PCR+ | PCR- | Total | |
| COVID-19 IgG/IgM Rapid Test | IgM+ | 74 | 2 | 76 |
| IgM+ | 5 | 225 | 230 | |
| Total | 79 | 227 | 306 | |
For IgG detection:
| Method | Convalescent samples | PCR- | Total | |
| COVID-19 IgG/IgM Rapid Test | IgG+ | 82 | 3 | 85 |
| IgG- | 1 | 224 | 225 | |
| Total | 83 | 227 | 310 | |
Results interpretation:
IgM Positive:*The colored line in the control region (C) changes from blue to red, and a colored line appears in the IgM test region. The result is positive for COVID-19 virus specific-IgM antibodies.
IgG Positive:*The colored line in the control region (C) changes from blue to red, and a colored line appears in the IgG test region. The result is positive for COVID-19 virus specific-IgG antibodies.
IgM and IgG Positive:*The colored line in the control region (C) changes from blue to red, and two colored lines should appear in IgG and IgM test regions. The color intensities of the lines do not have to match. The result is positive for IgM and IgG antibodies.
Negative: The colored line in the control region (C) changes from blue to red. No line appears in IgM or IgG test regions.
Invalid: Control line (C) is still completely or partially blue, and fails to completely change from blue to red. Insufficient buffer volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the procedure with a new test device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
