Coronavirus are a large family of viruses which may cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

IgM provides the first line of defense during viral infections, followed by the generation of adaptive, high affinity IgG responses for long term immunity and immunological memory. Therefore testing of COVID-19 IgM and IgG antibodies is an effective method for the rapid diagnosis of COVID-19 infection. Furthermore, detection of COVID-19 IgM antibodies tends to indicate a recent exposure to COVID-19, whereas detection of COVID-19 IgG antibody indicates a later stage of infection.

Covid 19 Test Principle
Covid 19 Test Principle

Intended Use:
The COVID-19 IgG/IgM Rapid Test is intended for use to qualitatively detect IgG and IgM antibodies of the novel coronavirus in human serum, plasma or whole blood in vitro. It's used as a supplementary indicator for the detection of suspected new coronavirus nucleic acid negative cases, or is used in coordination with nucleic acid detection in the diagnosis of suspected cases. It can not be used as a basis for the diagnosis and exclusion of new coronavirus infection pneumonia, and is not suitable for general population screening.

Recommended Group of people to be tested:
High Risk: Obvious clinical, Symptoms but Nucleic test Negative patient
Suspected: Family members of Confirmed or Suspected patients, Recent close contact person
Susceptible: Elderly, children or Immuno-suppressive persons
Confirmed: Continue monitoring of disease progress and monitoring of convalescent

Finger Stick/Whole Blood Sampling And Testing Procedure:

  1. Puncture a finger with a blood needle
  2. Suck blood with a dropper
  3. Add 10ul sample into sample well
  4. Add 2 drops of sample dilution into sample well immediately
  5. Wait 15 minutes
  6. Read results

Serum/Plasma Testing Procedure:

  1. Collect 10ul of serum/plasma.
  2. Add 2 drops of sample dilution into sample well immediately
  3. Wait 15 minutes
  4. Read results

Interpretation For Results
POSITIVE RESULT

1.Visible C-line and G-line indicates covid-19 IgG positive
2.Visible C-line and M-line indicates covid-19 IgM positive
3.Visible C-line, G-line and M-line indicates covid-19 IgG & IgM positive

NEGATIVE RESULT
Visible C-line indicates covid-19 IgG & IgM negative

Coronavirus Cases COVID 19 Clinic Significance
1. Nucleic Acid (PCR) positive, but IgM & IgG both negative. Patients may be in the ‘window period’ of SARS-COV-2 (Coronavirus) infection.
2. Nucleic Acid (PCR) and IgM are positive, but IgG negative. Patient may be in the early stage of infection, and the body’s immune response first produced the antibody IgM, but no IgG was produced or the IgG content did not reach the detection limit of the diagnostic reagent.
3. Nucleic Acid (PCR) and IgG are positive, but IgM negative. Patients may be in late or recurrent stage of infection.
4. Nucleic Acid (PCR), IgG and IgM all positive. Patient is in the active phase of infection, but the human body has developed some immunity to SARS-COV-2(Coronavirus) (the persistent antibody IgG has been produced).
5. IgM positive, Nucleic Acid (PCR) and IgG negative. Patient may be in the acute phase of SARS-COV-2(Coronavirus) infection. At this time, nucleic acid test result need to be considered (PCR may be false negative).
6. IgG positive, Nucleic Acid (PCR) and IgM negative. Patient may have been infected with SARS-COV-2 in the past, but the patient has been recovered or the virus in body has been cleared.
7. Nucleic Acid (PCR) negative, but IgM & IgG both positive. Patient has recently been infected with SARS-COV-2(Coronavirus) and is in the recovery stage. Or the nucleic acid test result is false negative and the patient is in the active infection stage.
