Anterior Nasal Swab

Description

Disposable sample collection swabs are suitable for the collection of microorganisms, which can assist hospitals or laboratories in virus detection or research virus sampling.

For biological samples from human or animal natural orifices, such as throat, nasal cavity, oral cavity, vagina, etc. use.

　　What are the steps of using the disposable sampling swabs used in different places? Let’s introduce the cases of nasopharyngeal swabs and anterior nasal swab. 

What is the difference between a nasopharyngeal swab and a nasal swab (anterior nasal swab)?

Are you getting the flu or COVID-19 test? You may be wondering what the difference is between a nasal swab test and a nasopharyngeal test. In this article, we explain the core differences between the two tests, and the swabs used to collect them.

What is the anterior nasal swab method?

The nasal swab method uses a swab to collect a diagnostic sample from the nasal membrane.

The nasal swab test (often called the anterior nasal test) involves inserting the swab approximately 2.5 cm deep into the nostril, rotating it in one nostril for 10-15 seconds (5 times) while touching both sides of the nasal wall.

And then using the same nasal A swab, collected in the other nostril in the same manner.

Because this method is less invasive, generally more comfortable for the patient – and also the method used when self-testing.

For nasal collection methods: usually, medium-sized tips made of absorbent material, usually flocked fibres, spun polyester, or medical foam.

The handle of the nasal swab used for this diagnostic test:  PP Stick or ABS.

What is the method of nasopharyngeal swab?

The nasopharyngeal collection method collects a sample from the nasopharynx, which is the upper part of the throat behind the nose. In this test, a small pointed nasopharyngeal swab is inserted into the nostril parallel to the chin until resistance is felt.

Inserted no deeper than half the distance between the nostril and the ear.

The nasopharyngeal flocked swab is then swirled a few times while remaining in place, and then slowly removed while gently swirling.

Less comfortable for the patient. But not considered painful.

Not recommended for self-testing and should only be performed by a healthcare practitioner.

Swabs for use in the nasopharynx are designed with a micro tip made of ultra-fine flocked material and a thin, flexible handle usually made of PP Stick or ABS.
