Cases where a quick test can be performed at home

In extremely dangerous areas such as areas with large numbers of sick people, a rapid antigen test is necessary as results are available within 15-30 minutes, no complicated equipment and laboratories are required, you can also self-test at home. Especially in cases where there are many F0 cases with fast spreading rate.

But if the rapid test result is positive, it needs to be confirmed by RT-PCR. At the same time, the harmonization of rapid antigen detection and RT-PCR detection in the same outbreak depends on the assessment of epidemiologists and labs.

One study found that rapid antigen testing was able to identify an average of 72% in people with symptoms, but only 58% in those without symptoms.

The screening effectiveness of rapid antigen test biologicals depends on the use case and manufacturer's instructions, and is generally best used when viral loads are highest (5-7 days after symptom onset). symptoms), or those who are asymptomatic but have been exposed to a high level of Covid-19 infection.

Instructions for quick Covid-19 test at home (oropharyngeal swab sample)

Warning:
Sampling is likely to cause pain / reflexes to cough and sneeze. People who test themselves at home need to find a well-ventilated place, without air conditioning, without a roommate to limit the spread of infection through tiny droplets.

I. Before sampling

• Carefully read the instructions for using the quick test:
• The person taking the sample needs to clean and disinfect his hands.
• Blow your nose before performing the collection. Note blowing your nose into a tissue and discarding it immediately to limit splashes into the outside environment.
• If you need advice, guidance and support, contact the community COVID-19 team or local health agency.

II. Sampling Process

Materials used for 1 test:

• Test tray
• Sample extraction buffer
• Sterile sampling sticks
• Sampling tube with dropper cap
• Sampling tube holder
• Instruction sheet
• Watch or phone to keep track of time

It is recommended to let the items equilibrate to room temperature (from 15-30 degrees Celsius) about 30 minutes before testing

Step 1: Prepare for sampling

• Place the sample extraction tube holder on a clean horizontal surface
• Place 10 drops (equivalent to 300 L) of sample extraction buffer into the extraction tube and place on the stand
• Remove the test tray from the pouch and use it as quickly as possible within 1 hour.
• Place the test tray on a clean flat horizontal surface.
• Remove the sterile sampling strip from the bag and proceed to collect the test sample

Step 2: Collect samples

• Sampling sitting position, head tilted back at an angle of 70 degrees.
• Put the sampler through the nostril, push deep into the pharynx until there is an obstruction, then stop. Rotate the rod 3 times and hold it for 5-10 seconds.
• Gently rotate and remove the sample stick from the tip

Step 3: Extract the sample

• Dip the tip of the sampling probe into the extraction tube. Rotate and rub against the wall and bottom of the tube 10 times. Let the stick soak in the solution for 1 minute.
• Squeeze the 02 walls of the tube against the tip of the stick. Slowly rotate the rod and squeeze the tip of the stick when withdrawing to get as much fluid as possible
• Close the tube tightly with the dropper cap. Shake the tube vigorously horizontally 10 times to mix the sample well. Avoid letting the solution reach the filter tip in the dropper cap.
• Add 3 drops (equivalent to 100 mL) of sample extract from the tube into the sample receiving cell of the test tray and start the night time

Step 4: Read the result

Read results after 15 minutes. Do not use results after 20 minutes.

• Negative: Only the control line C appears. The results indicate that the sample does not have SASR-CoV-2 antigens or that their concentrations are below the test's detection threshold.
• Positive: The C control line and the T result line appear. The results show that the sample has SASR-CoV-2 antigen.
  With a positive result, it is necessary to stay calm, wear a mask, do not contact others, stay at home, keep a medical distance.
• Immediately notify the community COVID-19 team, local health – Hot road 18001119. At the same time, immediately notify the health agency for guidance and organize isolation and timely handling.

Step 5: Discard used test material

• Tested materials need to be collected, sealed in a separate bag, placed in a fixed place and collected and handled by functional units according to regulations.
• The rapid test is a screening test and should be used in the early stages of onset for best results.
• The result is invalid if the control line does not appear C. It is caused by missing sample or damaged test tray. Repeat another new test TEST or contact your health care provider for advice and support.
• Don't be subjective, ignore epidemic prevention and control if there is a negative rapid test result, still ensure compliance with 5K and medical instructions of local health authorities. A negative result still does not completely rule out the possibility of SARS-CoV-2 infection and must be considered in the specific epidemiological context. If necessary, the results should be confirmed by RT-PCR.

Are the results of the Covid-19 quick test at home accurate?

The accuracy of SARS-CoV-2 rapid antigen test results is about 80%

Rapid antigen detection is performed only as a screening test, not a confirmatory test, because the accuracy (sensitivity, specificity) is not equal to that of the RT-PCR test. When using rapid antigen detection to detect positive cases, the RT-PCR test must be repeated to confirm.
