What is a COVID-19 Rapid Antigen Test

A result from the rapid antigen test (RAT), which checks for COVID-19 quickly, is available in 15 to 30 minutes. Every test kit has a QR code that connects to a video that demonstrates how to administer the test.

The right time to finish a Rapid Antigen Test

It is advised to utilize RATs if

  • going to a busy event with lots of people, such as a wedding or funeral
  • interacting with a person who is susceptible to COVID-19 hazards.
  • going to a high-risk location, such as a hospital, nursing home, or home for people with disabilities
  • You experience signs
  • You must immediately check for COVID-19.

Follow the Department of Health’s recommendation.

What is a COVID-19 Rapid Antigen Test

For the benefit of the WA community, free Rapid Antigen Tests (RATs) are offered to help with the cost of living concerns and to encourage routine COVID-19 testing. For further details, go to the WA free RAT program website.

RAT kits may also be purchased from pharmacies, grocery stores, and other merchants.

Performing a Rapid Antigen Test

Two categories of RATs exist:

  • Saliva test, which involves spitting into a tube or sucking on a swab.
  • The user swabs each nostril with a nasal swab.

In self-test kits, you’ll find:

  • Test equipment
  • A nasal swab or spittle funnel
  • A test tube with a dropper top for sample collection
  • Deffer (a chemical solution that extracts the virus from samples)
  • Useful information

RATs for young people

All RAT kits include instructions on how to utilize them. Make sure the RAT is appropriate to use on kids and carefully follow the directions. RATs on children should be carried out or overseen by parents or guardians. Some individuals find it simpler to utilize “lollipop” saliva tests on small children.

A line adjacent to the C marker and no line next to the T marker indicates a bad outcome. You don’t need to isolate if your test is negative, you don’t exhibit any symptoms, and you don’t have any close contacts.

A line is placed next to the C and T marks to indicate a successful test. If you test positive, you must isolate for at least 5 full days and report your results online to WA Health. After five days, if you are still experiencing symptoms, keep to yourself until they go away.

If there is just one line next to the T marker, your test results are invalid. This may occur if the test was conducted poorly or has a flaw. If this occurs, you must take a second test by registering for a free PCR test or retaking the RAT.

Adults and children are given step-by-step instructions by the emergency room nurse.


You have probably seen COVID-19 quick antigen test kits on sale at pharmacies, grocery shops, and online. Alternatively, it’s possible that the federal government, which is now sending one billion test kits to families throughout the country, is the source of your free kits. (You may place an order here.)

The quick antigen tests are practical and provide findings in 15 to 20 minutes. Self-testing, together¬†with immunization, masking, handwashing, and social seclusion are crucial tools in the fight against coronavirus. It’s crucial to do the test correctly to get the most accurate results.

Claudio Alvarado, an assistant nurse manager in the pediatric emergency department at UC Davis Children’s Hospital, said, “We receive a lot of inquiries from families about how to administer the tests and how accurate they are. Although they are not difficult, it is crucial to carefully follow the instructions.

An instruction manual for doing a COVID-19 fast antigen test at home

  1. Spend at least 30 seconds thoroughly washing your hands with warm water and soap.
  2. Two tests are included in the set. A collecting swab, a test strip, and a tiny vial of liquid are the three primary components of each. Put each of them on a spotless surface.
  3. After opening it, place a collection swab into each nostril and rotate it five times against the inner wall. The swab should be inserted between 12 and 34 of an inch into the nostrils. Alvarado said, “A nice way to picture that is it’s roughly the size of the tip of your pinkie finger.” Then place the swab back into its packing; you’ll need it again. “Though it doesn’t hurt, it does feel extremely strange.”
  4. Tap the liquid vial’s bottom three times on a solid surface.
  5. Swab into the vial after opening the big top and stirring it 15 times.
  6. Pull the swab out while pressing the vial’s sides against it. This is an important step since it makes sure you have the whole collection, according to Alvarado. After that, replace the vial’s cap.
  7. Activate the test strip. Alvarado added, “You’ll notice that it has both a “C” and a “T.”
  8. Squeeze three drops of your sample into the strip’s collecting area by opening the smaller, top cap of the liquid vial.
  9. Set a 15-minute timer. During this period, refrain from touching the test strip.
  10. Read the exam.

How to interpret the outcomes of your at-home test kit

You’re going to check for two things after 15 minutes:

  • The control is a line beneath the letter “C.” If there isn’t a line under the “C,” you’ll need to retest, Alvarado said. “It’s crucial that you receive a line under the “C” because it signifies that the test is successful.
  • If there is absolutely no line in the region beneath the “T,” which stands for the test section, the result is COVID-19 negative. The test is positive for COVID if there is a line beneath the “T.” No matter how light or dark the line beneath the “T” is, Alvarado insisted that its presence indicates a positive COVID test.
