Cracking the Code: Optimal SARS-CoV-2 Testing for Omicron

Cracking the Code: Optimal SARS-CoV-2 Testing for Omicron

Posted on by

With the emergence of the Omicron variant, determining the most effective testing methods for SARS-CoV-2 became crucial. Researchers aimed to understand how different sampling methods—nasopharyngeal (NP), nasal, oropharyngeal (OP), and saliva—compare in detecting Omicron using RT-PCR and antigen tests.

As self-testing gained popularity and debates over sampling methods intensified, this study aimed to fill in the knowledge gaps surrounding viral load differences and diagnostic effectiveness.

Research Overview: Two Cohorts, Multiple Sample Types

The study took place in Atlanta during Omicron’s peak in January 2022, involving two cohorts: a family cohort that self-collected nasal, OP, and saliva samples, and a larger, cross-sectional cohort of 121 symptomatic individuals whose samples were collected by trained staff. Both cohorts’ samples were tested using RT-PCR and ultrasensitive antigen testing to assess viral loads across different sample types.

Flocked Swabs and Custom Swab Manufacturing

ISO13485 quality management system for the production of disposable sampling swabs, quality standards, sterile swabs.

Family Cohort Findings: Nasal-Predominant Viral Load

For the family cohort, self-collected nasal swabs consistently showed higher viral antigen levels and lower cycle threshold (Ct) values, indicating a larger quantity of viral RNA compared to OP and saliva samples. This result suggested that nasal swabs might consistently capture a “nasal-predominant” viral load across various timepoints of infection, providing useful insights into testing strategies.

Cross-Sectional Findings: Mixed Viral Load Phenotypes

In contrast, the cross-sectional cohort displayed mixed viral load phenotypes. There was no clear dominance of any sample type across 39 confirmed positive cases. While some individuals showed a “MT-predominant” viral load, others exhibited an “OP-predominant” phenotype. Interestingly, saliva consistently showed higher antigen levels than both MT and OP, although it did not correlate with improved diagnostic performance.

Diagnostic Performance: RT-PCR and Antigen Sensitivity

The study assessed diagnostic accuracy using RT-PCR and antigen tests. RT-PCR testing showed high positive percent agreement (PPA) ranging from 89.7% to 94.4% across MT, OP, and saliva samples, with minor overlap. Antigen tests, however, had a lower PPA, from 64.9% to 91.4%, depending on the clinical cutoff. Combining MT and OP samples slightly increased sensitivity but did not provide a statistically significant improvement over MT alone.

Symptom Correlations and Viral Load

In subgroup analyses, symptoms like sore throat and rhinorrhea appeared to influence viral loads in specific sample types. Participants with sore throats had higher OP viral antigen levels, while those with rhinorrhea showed higher MT antigen levels. This suggests that symptom-based selection of sample types could help optimize testing strategies.

Factors Affecting Viral Load

Statistical modeling revealed that sample type played a significant role in antigen concentration, but not in cycle threshold (Ct) values. Interestingly, factors like the duration of symptoms and vaccination status did not significantly impact the Ct or antigen levels, highlighting the variability of viral load across different sample types.

Key Takeaways and Future Implications

Flu Test Throat Swab China Factory And Manufacturers

A throat flocked swab for influenza is more accurate.Throat swab testing for influenza is very fast, economical, and simple.

This research did not identify a single best sample type for SARS-CoV-2 detection during Omicron’s prevalence. However, the findings suggest that combining MT and OP samples might increase sensitivity. The potential role of symptoms in predicting the most effective sample types also warrants further investigation. While saliva showed high antigen levels, the lack of validated saliva rapid tests limits its clinical utility. Ultimately, more extensive studies are needed to confirm these trends and refine testing strategies.

For accurate and reliable sample collection, consider using Yousuto OP swabs, designed for optimal viral detection and improved diagnostic results.

The outbreak of the novel coronavirus pneumonia in 2020 on a global scale has brought significant losses to human society. Viral nucleic acid detection plays a key role in epidemic prevention and control.

As the first step in viral nucleic acid detection, specimen collection is an indispensable link.

The amount of virus collected and released by sampling swabs is directly related to the positive rate of nucleic acid detection. As the gold standard, nucleic acid detection plays an important role in virus detection, and the role of swabs as a sample collection tool should not be underestimated. Among them, throat swabs and nasal swabs are most commonly used, and anal swabs are also used as auxiliary tests.

During the epidemic, researchers from various countries analysed and found that the efficiency of flocking nasal swab sampling and the acquisition of virus samples were the best.

At the same time, in order to solve the problem of the shortage of nasal swabs.

Nasal swabs

Nasal swabs

The researchers proposed a combined sampling method of oropharyngeal and nasal swabs to achieve the same effect as nasal swabs.

As the main tool for sampling, swabs have important applications in the fields of forensics, clinical medicine, and environmental testing.

Swabs of different materials, such as rayon, foam, polyurethane, polyester, flocked nylon, etc., will have different structures and performance differences and have different collection effects for different specimens such as protein and nucleic acid, which will affect the detection.

The selection of appropriate swabs according to different sampling samples and testing indicators is very important for testing, and the proper use of swabs is also very important for sample collection and the safety of medical staff.

The cotton swab used to poke the throat or nose during the nucleic acid test of the new crown should be called an aseptic sampling swab, also called a pharyngeal swab. According to different sampling sites, including nasopharyngeal swabs and oropharyngeal swabs.

The swab is in direct contact with the nasopharynx or oropharynx to absorb the secretion sample, then put the head with the secretion into the culture solution, break the handle through the breakpoint, seal the lid and send it for testing.

Nasopharyngeal Sampling Procedure

Nasopharyngeal Sampling Procedure

In this process, the swab involves two links: sampling and elution (release the collected sample into the culture medium). The choice of different materials will affect the efficiency of sampling and release, and also affect the correctness of PCR detection. There are certain requirements for the material of the sampling swab.

PCR TEST

According to different materials, common swabs can be divided into medical cotton swabs, foam swabs and flocking swabs.

Several reports have shown that the sensitivity of medical cotton swabs in collecting respiratory samples is low, and natural fibres such as cotton have strong adsorption to proteins, which is not conducive to the subsequent release in the culture medium.

Generally, cotton swabs also have wooden handles, which may adsorb proteins during storage and interfere with virus detection. In addition, the wooden handle is too hard to break, and can also cause safety problems when sampling.

The US CDC recommends that the swab head material— synthetic fibres. The use of calcium alginate swabs or swabs with wooden shafts may inactivate certain viruses and reduce Accurate substances.

The nucleic acid test (PCR TEST) uses a flocked swab instead of a cotton swab.

Flocking is a craft, not a material

　　 Flocking is not the fluff of any plant, but a very common fabric treatment process.

         Widely used in the textile industry, automobile manufacturing, printing industry, chemical industry and other fields.

　　 The flocking process means vertical fixing of some cut or milled short fibres to some kind of adhesive-coated surface. Short fibres are usually nylon, polyester, or other artificial fibers. The range of planting them is very wide, and surfaces such as cloth, plastic, wood, leather, paper, etc. can be flocked.

　　Flocking only needs three things, 1, short fibers; 2, adhesive, 3, some kind of surface

　　 Flocking is very common in everyone’s life, just usually without realizing it. For example, flocking fabrics can be found on clothes, curtains, carpets, and furniture. Usually, those surfaces that are fluffy and comfortable to the touch are brought by the flocking process.

　　 In addition to the decorative effect, the flocking technology has also been tried by scientists to make graphene lithium battery anode sheets; make special lipophilic and hydrophobic materials to absorb marine oil spills, etc.

The principle of flocking

　　 At present, the most commonly used flocking method is electrostatic flocking. After the fluff enters the high-voltage electric field, it contacts the negative electrode and is negatively charged. 

　　 Don’t worry if some fibers fall to the side and don’t stick to the side. After they touch the positive electrode side, the negative charges on the surface are completely neutralized, and they will fall to the negative end due to the force of the electrostatic electric field. Repeat the above movement until they are all stuck.

Flocked swabs for nucleic acid testing

　　 The flocking swabs used for nucleic acid detection are mostly “planted” with nylon short fibers. The reason for choosing flocked nylon over cotton swabs is the functional need for sampling.

Flocked swab

Flocked swab

Any material design is purposeful, and flocked swabs for nucleic acid detection need to meet the following characteristics:

　　  ② After the swab is put into the preservation solution, it has to “let go” to release the biological sample, and it cannot hold the sample firmly for a second or divide it. ③ It cannot react with biological samples and destroy the samples.

　　 Because cotton itself has superior hydrophilicity and adsorption, once it comes into contact with the sample, it is like the characters in Qiongyao play. In contrast, nylon flocked swabs are like a scumbag “can take it and put it down.

　　 Therefore, the collection and release volume of nylon flocking swabs is much larger than that of traditional winding cotton swabs. Experimental studies have shown that the collection and release volume of flocking swabs can reach 95% of the samples, while cotton swabs are only about 20%.

　　In fact, the ability of cotton swabs to grasp the sample is not bad, but after inserting the preservation solution, the flocked swab can quickly let go of the sample to be eluted, but the cotton swab will make the cells stuck in the fiber mass and cannot be separated.

　Otherwise, the nucleic acid will be degraded before the detection begins, and the correct result will definitely not be detected.

　　 Because of this, it is superfluous to worry that nylon is a synthetic fiber that is harmful to the human body. Flocked fibers have even been tried in regenerative medicine to help repair damaged bones and cartilage. By implanting the flocked fibrous scaffold, the properties of the extracellular matrix are modeled, allowing stem cells to adhere to it to proliferate and differentiate; and provide sufficient space for the newly synthesized matrix and capillaries to enter.

Conventional fiber swab: The sample is trapped by the gaps in the fiber mass, that is, the sample is penetrated, diluted, and trapped in the fiber. The acquisition is slow, the release is even slower.

 

 

 

Nylon flocked swabs: Superior sample collection/release capability, >80% release rate

The time for flocking swabs to collect samples is 3-5 seconds, while the time for cotton swabs is 15-120 seconds, or even longer, which causes pressure on staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

3. Why are flocking swabs more advantageous for micro DNA collection?

Due to the internal structure of traditional cotton swabs, which are entangled with cotton fibers at the top, the sample will be dispersed by its fiber clusters and remain in the fibers during sampling, resulting in lower precipitation efficiency of DNA with low content, and even causing false negatives in the test. result.

The unique structure of the top of the flocking swab can almost completely extract and separate out a very small amount of DNA, so the flocking swab has a more obvious advantage in the collection of trace DNA.

Swab Step 1: Hold the handle and gently insert the sampling swab into the mouth.

Step 2: Gently rotate the sampling swab for 3-5 turns, then slowly take it out

Step 3: Put the extracted sample into the sample collection tube, break the handle, and seal it immediately to complete the sampling.

The newly developed sampling swab nylon flocked sampling swab head has soft flocking hair, and the absorption and release force is 3 times greater than that of trapping microorganisms in traditional sampling swabs, and it will not cause epithelial damage to patients.

The short nylon fibre acts like a soft brush, which can effectively improve the collection of cellular material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby ingesting the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to elute.
