Deep Nasal Swab Virus Respiratory Kit

As of April 30, local time, the number of new coronavirus patients in the United States has reached 81.2 million, and the number of deaths due to new coronavirus infection has exceeded 992,000.

As the government ramps up testing for Covid-19, many of us ordinary people are now being tested for Covid-19.

What is Deep Nasal Swab?

Deep Nasal Swab ( nasopharyngeal swab ) is actually a relatively long collection swab, similar to a relatively long sterile swab.

Its main function is to take nasopharyngeal secretions for bacterial culture and drug sensitivity tests.

The source of infection in the nasopharynx and the microorganisms in the nasopharynx were selected and identified by bacterial culture and drug sensitivity test.

Then a drug susceptibility test can be done to determine which drugs are sensitive so that sensitive drugs can be selected for treatment.

So that a better curative effect can be achieved, so the nasopharyngeal swab is actually a flocking swab for collecting nasopharyngeal samples.

Why deep nasal swab for covid?

The Deep Nasal Swab test: to collect cells deep in the nasal cavity because the nostrils by themselves do not provide a sufficiently accurate sample.

The collected fluid samples are sent to a laboratory for PCR testing (polymerase chain reaction), a standard scientific procedure that involves using samples provided by patients to build models of their DNA.

In this system, technicians can look for evidence of the genetic material (RNA) from the new coronavirus, which is wrapped in the patient’s own DNA if they are infected with the virus.

Both Public Health England and the US Centers for Disease Control and Prevention (CDC) prefer to use Deep Nasal Swab because it is so accurate.

Unfortunately, for suspected Covid-19 patients, it can be uncomfortable.

During the operation, the medical staff is gentle and skilled, so there will be no pain.

What is the correct depth and length of nasopharyngeal swab collection?

See the length of the nasal swab? See how deep it goes into your nostrils?

The length of the nasal swab is normally about 15cm, and it should enter about 2/3 of the time when doing the collection.

The nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.

About the distance from the tip of the nose to the earlobe, insert a thin cotton swab into the nostril, from the lower nasal passage to the posterior wall of the nasopharynx, and then turn the front to take a sample. The swab will have a significantly insufficient depth of entry. So the posture must be correct.

When the throat swab enters in the direction of the earlobe if it encounters resistance, it needs to adjust the direction, rotates it slightly, and cannot forcefully enter it.

Otherwise, damaged. Until the bottom of the rhinitis is reached, there is a general sense of resistance against a wall.

When you feel a sense of resistance, you have reached the bottom of the nasopharynx. At this time, you need to keep the nasopharyngeal swab at the bottom of the rhinitis for 10-15 seconds. After fully contacting the secretion, rotate it and pull it out.
