The Results of the COVID-19 Rapid Test: Every Line Matters!

The COVID-19 rapid test is one way to detect the corona virus in a person’s body. This rapid test use a blood sample and the results appear within 15-30 minutes.

The blood sample being test is use to determine the condition of the antibodies in the body as a result of the reaction against the virus.

In the rapid tool there are three indicators which are Control (C), Immunoglobulin G (IgG) and Immunoglobulin M (IgM).

Then how to read the rapid test results?

Immunoglobulin G (IgG) is an antibody that forms 5-7 days after a person is exposed to the virus or immunization. Meanwhile, Immunoglobulin M (IgM) is an antibody that appears shortly after a person is exposed to a virus or immunization.

After taking a blood sample, if there is no line that appears in all three indicators, it means the test failed and must be repeated. Here’s how to read the results based on three indicator lines:

  • NEGATIVE or NON-REACTIVE if only one line appears on the Control (C) indicator.
  • POSITIVE or REACTIVE if three lines appear on all indicators C, IgG and IgM or on two lines between IgG and IgM. If the line appears on IgM it means that the person is in the early stages of infection. But if the line appears in IgG and IgM, the patient is consider to be in the active infection phase. Meanwhile, if only on the IgG line indicator, it means that a person is in the final phase of infection until he is cured. Or it can also mean that he has a history of COVID-19 infection.

However, we have to remember that this rapid test has low accuracy. It could be that those who are negative are in a window period so that the infection has not been detected. Its important for them to do self-isolation and retest again in the next 10 days.

So even on the positive results but no symptoms, better to do self isolation and retest 10 days later.

Both negative and positive results from the rapid test, it is better to confirm it through Polymerase Chain Reaction or PCR / SWAB which is more sensitive and has high accuracy.

  1. Howdy would you mind stating which blog platform you’re working with? I’m going to start my own blog soon but I’m having a difficult time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I’m looking for something completely unique. P.S Sorry for being off-topic but I had to ask!

  2. Have you ever considered about including a little bit more than just your articles? I mean, what you say is important and everything. But think about if you added some great photos or video clips to give your posts more, “pop”! Your content is excellent but with pics and video clips, this blog could certainly be one of the very best in its niche. Excellent blog!

    1. thanks for the suggestion. I acctually use some videos on my previous article. I also use images, but it really depend on the needs of the article. Video and images make our post more “pop” for sure, I agree with you. Thanks again
