Application scope of CM company virus sampling tube

It is suitable for the detection and sampling of COVID-19, influenza virus (including general influenza, highly pathogenic avian influenza, influenza a H1N1, etc.), hfmv, measles rubella and other types of viruses.

CM company virus sampling tube

The sampled virus and related samples shall be stored and transported within 48 hours under refrigeration (2-8 ℃). Long time storage of relevant samples in – 80 ℃ environment or liquid nitrogen environment.

Advantage

The number of viruses collected and released by CM virus sampling tube is much higher than that of ordinary product. It ensures the activity and integrity of virus particles, and provides the primary guarantee for subsequent virus isolation and nucleic acid detection.

As the northern hemisphere gradually enters the autumn and winter season, the form of the epidemic is still not so easy to control.In order to further improve the positive rate of nucleic acid detection, we will show you the collection methods and notes of nasopharyngeal swabs with simple graphics and pictures.

The biggest difference between nasopharynx swab and oropharyngeal swab is that the sampling position is different. That is, oropharynx and nasopharynx. In clinical trials, the positive rate of nasopharynx is relatively higher than that of oropharynx, but the operation requirements of nasopharynx sampling are relatively high and the action should be relatively gentle. In order to improve the positive rate, these patients may take nasopharyngeal swabs again. Comprehensive judgment can improve the diagnostic rate.

Pharyngeal swab is to wipe the tonsil and posterior pharyngeal wall

What is a oropharyngeal swab?

Pharyngeal swab is used to examine throat diseases.

It is a detection method to understand the patient’s condition, oral mucosa and throat infection.

What is COVID-19 nucleic acid testing using throat swabs?

Oropharyngeal Sampling

Because COVID-19 is mainly spread through droplets and contacts, plus the ACE2 receptor necessary for COVID-19 invasion in the respiratory tract, the respiratory tract of the infected person is the main gateway for COVID-19 invasion.

How to pharyngeal swab sampling ?

1. Tear off the outer package of the sampling swab and take out the sampling swab;

2. Expose the throat and press the tongue down with a tongue depressor if necessary;

3. Take out the sterile swab, gently and quickly wipe bilateral pharyngeal tonsils and posterior pharyngeal wall for 3 times, and put the swab head into the preservation solution,

4. Buckle and fold the tail of the swab at the mouth of the storage tube, discard the tail, tighten and cover the tube cap,

5. Check the patient’s name again after sampling;

6. Put it into a sealed bag and a special transfer box, and quickly send the samples to the laboratory for inspection.

About medical flocked swab

Posted on 2021年8月18日2021年12月21日 by Dr. Lee

DNA flocking swab is suitable for human and animal use. It has advantages over other DNA samples in design. Its unique sample matrix and rapid release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilized with ethylene oxide and passed the detection of human DNA contamination.

flocked swab

Flocking DNA oral test is specially used to improve the yield and quality of genomic DNA in oral test cells. Oral cell sample is a good non-invasive collection and detection method instead of blood. Combined with DNA separation and stabilization kit, it can quickly collect high-purity and complete DNA samples.

characteristic

The unique test substrate greatly improves the yield of DNA

Adult oral test piece 1 to 10 μ g DNA

It is a good alternative to blood collection

Both human and animal can use it

Simple and fast operation

There are two types of single and double disinfection packaging to choose from

application

Genotype study

Veterinary genotyping and diagnosis
