Flocked Swab Of Viral Transport Media Test Covid Specimen Collection

Description

Flocked Swab Of Viral Transport Media Test Covid Specimen Collection

CellMedical® Flocked Sampling Swabs: Constructed with nylon short-fibre fleece tips and medical-grade ABS plastic rods that collect and release 3 times more samples than traditional swabs. Moreover, it does not cause damage to the cell sample, ensures the survival rate of the cell sample, and does not leave fatty acids. It will not affect the test results, and will not cause harm to the human body.

Widely used in the field of genetic testing.

The collection and release of flocked swab samples are as high as 95% and are widely used for the collection and transportation of body fluids, cells, microorganisms and viruses.

Nasopharyngeal Swab vs Oropharyngeal Swab

Do you know the standardized operation process for the collection of COVID-19 throat test samples?

A throat swab is currently the most important sampling method for diagnosing new coronavirus infections. Correct sampling is the key to improving the accuracy of throat swab nucleic acid detection specimen collection. What are the factors that affect the accuracy of specimen collection for throat swab nucleic acid testing? There are three main aspects:

Depth of throat swab collection
Contact time of throat swab with mucous membrane
Throat swab sampling “point to point” or wipe

(1) Tips for collecting oropharyngeal swabs

1. Body position during sampling: take a sitting or semi-recumbent position, with the subject’s head slightly tilted, mouth wide open, and the head resting on the wall or on the back of the chair.

2. Standardize the sampling operation: use the tongue depressor to press the subject’s tongue, and ask to make a long “ah–” sound.

The doctor used a throat swab to perform “up and down three back and forth quick wipes” and “left and right three back and forth quick wipes” on the patient’s bilateral pharyngeal tonsils to avoid contact with the tongue, teeth, and gums.

In case of discomfort, quit and rest for a while and try again.

3. Precautions: Drinking water before oropharyngeal swab detection will dilute the virus attached to the pharynx, especially drinking hot water will inhibit the activity of the virus.

In order to improve the accuracy of throat swab nucleic acid detection, 15-30 hours before detection In order to ensure the high accuracy of throat swab nucleic acid detection, the subject is instructed not to drink water in minutes.

For patients with good throat exposure, we do not recommend a long “ah-” to reduce the occupational exposure risk of the sampler.

(2) Tips for collecting nasopharyngeal swabs

1. The sampler stands at the side of the subject to take samples. And the subject is required to pull down the mask to expose only the nostrils. Once the sneeze reflex occurs, the subject can cover it with an elbow or a tissue. And the sampler is not directly in front of the subject, exposing the risk quite lower.

2. Standard sampling operation: “one insertion, two stops and three rotations”. – measure the distance from the tip of the nose to the front of the ear, half the insertion length, usually about 4 cm for adults. stay for 15-30 seconds to absorb nasopharyngeal secretions. (It depends on the patient’s tolerance, and the minimum stay time is not less than 3 seconds;
