What are the requirements for sampling swabs
Since the outbreak of the epidemic,
The virus sampling tube and nucleic acid test throat swab have been pushed to the cusp of the storm.
Many people worry that irregular sampling swabs will cause false positives or false negatives.
Because this will not only threaten personal safety but also cause great harm to society, the result will be very serious.
so the National Health Commission issue the “New Coronary Pneumonia Laboratory Testing Technical Guidelines (Third Edition)” in the specification requirements: (The original text is quote here)
Pharyngeal swab: Use two plastic rod swabs with polypropylene fiber heads to wipe both pharyngeal tonsils and posterior pharyngeal wall at the same time,
and immerse the swab head in 3mL virus preservation solution (isotonic saline solution, tissue culture solution or Phosphate buffer solution),
discard the tail, and screw the cap tightly.
Have you see that the clear material requirements for swabs in my country’s guidelines require polypropylene fiber,
but the manufacturer that produces swabs needs to pay attention to not using wooden stick swabs and calcium alginate swabs.
Why What? Please look down
Let’s take a look at the requirements for sampling swabs use in the collection of nasal and pharynx samples in “InterimGuidelines for Collecting,
Handling, and Testing Clinical Specimens from Patients Under Investment (PUIs) for 2019NovelCoronavirus (2019-nCoV)” issued by the United States CDC.
The original text is: Use only synthetic fiber swabs with plastic shafts .
Do not use calcium alginate swabs or swabs with woodeen shafts,
as they may contain substance that inactivate some viruses and inhibit PCR testing.
Place swabs immediately into sterile tubes
The translation is: only synthetic fiber swabs with plastic rods can be use.
Calcium alginate swabs or wooden stick swabs cannot be used，
because they may contain substances that inactivate certain viruses and inhibit PCR detection.
We all know that the United States CDC has high requirements for the materials of medical devices,
and this time is no exception, and it explains why wooden stick swabs and calcium alginate swabs cannot be used.
China also has clear regulations on sampling swabs, so manufacturers must not be sloppy in this regard.

Nasopharyngeal swabs are actually relatively long sampling swabs.
Not only are relatively long disinfection sampling swabs, but their main function is to use nasopharyngeal secretions for bacterial culture and drug sensitivity testing.. Through bacterial culture and drug sensitivity test, the source of infection in the nasopharynx and the microbes in the nasopharynx can be selected,
and then a drug sensitivity test can be done to determine which drugs are sensitive,
so that sensitive drugs can be selected for treatment, so as to achieve better results Effectiveness,
so the nasopharyngeal swab is actually a sampling swab for taking tissue samples.
Normal people’s pharyngeal isthmus culture should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur under the body’s systemic or local resistance and other external factors to cause diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, and acute pharyngitis.
①. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity. The collector can stand on the side of the collector, reducing occupational exposure caused by coughing and sneezing, and alleviating the pressure on the collector.
②. Measure the distance from the nostril to the root of the ear with a swab and mark with your hand.
③. Gently insert the swab into the nostril in the direction perpendicular to the nose (face) through the nasal cavity, with a feeling of touching the wall until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then gently rotate it 3 times.
④. Put the swab into the virus transport medium, not only to break the swab stick, but also to put it completely into the test tube.
⑤. Tighten the cap of the tube, mark it, put it in a plastic bag and seal it.
⑥. Submit the specimens for inspection in time

Precautions for collecting nasopharyngeal swabs
Guangdong has also officially entered the autumn season. Although it is still hot as before, it also feels like the autumn wind is coming. The weather turns cooler, and the temperature difference between morning and evening is large. In this season, it is inevitable that there will be nasal itching and nasal congestion and sneezing. Symptoms. In this special period of this year, we will be very worried about whether we will be infected with the virus. At this time, we will go to the hospital to take a nasopharyngeal swab to see what is going on, then go to the nasopharynx What issues should we pay attention to with swabs? Let’s take a look
① Please do not take antibiotics a few days before the nose swab;
②Do not use disinfectant mouthwash or smear the local lesion a few hours before the nasal swab
③. Do not eat, smoke or drink for a few hours before the nasal swab.
① The sampler stands on the side of the patient to take the sample,
②. The patient is required to pull down the mask to expose only the nostrils. Once the sneeze reflex occurs, the patient can be covered by the elbow or paper towel. The sampler is not in front of the patient, and the exposure risk will be lower.
③. If the patient’s turbinate hypertrophy, nasal passages are narrow, and the nasal swab insertion feels resistance, you can try to change one side of the nasal cavity or directly change to oropharyngeal swab collection.
④. People with nasal allergies are prone to sneezing, and oropharyngeal swab sampling is recommended.
⑤ Remember to wear a protective mask/face screen. For individuals who are highly suspected or basically diagnosed, or have severe coughs and hiccups, they should wear protective clothing.
⑥ After sampling, change gloves, perform hand sanitation and disinfection, and spray disinfectant on areas where the patient has touched.
Well, we still need to pay attention in special periods. Remember to wear a mask and personal hygiene when you go out. Once you find the virus is infected, please isolate it to avoid spreading it again.

Throat Swab Culture
Do you know what is throat swab culture? Have you learned about throat swabs before? Curious? Let me take you to discuss it today.These infections can include strep throat, pneumonia, tonsillitis, whooping cough, and meningitis.
The purpose of a throat swab culture is to detect the presence of organisms in the throat that could cause infection. For example, the presence of group A streptococcus bacteria (Streptococcus pyogenes) in your throat is a key sign that you may have strep throat.
Streptococcal bacteria are very contagious. They only need a little droplet in the air to spread quickly. An infected person can easily pass the bacteria on if they cough, sneeze, or share food or drinks. The bacteria can also be picked up from doorknobs or other surfaces and transferred to your nose, mouth, or eyes.
If you have a sore throat and your doctor suspects that you may have strep throat or another bacterial infection. The results of the test will help you and your doctor form a diagnosis and a treatment plan.
Because the pharynx is affected by infections caused by external bacteria when the body’s body or local resistance is reduced, the doctor needs to collect some cells or viruses for observation when we seek medical treatment, so as to understand the patient’s disease Illness. At this time, the throat swab can make its debut, and use its life-long learning and only use (sampling) to the extreme.
① First, we take out the disposable throat swab, gently tear off its outer coat, and then gently take it out (be careful not to touch other things before reaching the pharynx, to avoid contamination)
②. Then let the patient open his mouth at room temperature to fully expose his throat. When he sees his uvula, pharyngeal arch, or tonsil, quickly wipe the twirling secretions with a swab. Pay attention to the twirling action. Be gentle, so as not to cause throat discomfort or vomiting
③. After the collection is completed, please quickly take the throat swab out of the patient’s mouth, and then quickly put it into the sampling tube, break off the throat swab handle at the place with the broken mark, cover the sampling tube cap, tighten and save it, ( Be careful not to rotate too many times, so that the sample may be diluted or lost. After sampling, make sure that the throat swab does not touch other objects)
Okay, the mission has been completed. Let’s take a look at its product performance. First of all, the appearance. The shape of our swab should be correct, neat, smooth, uniform in color, free of burrs, mildew, scratches, and scratches. If there are defects such as marks, cracks, etc., a qualified swab should be very clean, without odor, and should be soft to the touch, without macular spots, stains or foreign objects. Then the swab should be able to withstand 4N static pressure perpendicular to the axial direction for 15s without permanent deformation or breaking. The breaking force of the depression at the sampling tip should be no less than 2N.
Finally, I would like to talk to you about the precautions of throat swabs. Pharyngeal swabs are suitable for the inspection and collection of biological parts such as natural cavities of any age. However, flocking has a very light tingling sensation on the skin, so before use, the little cuties who are allergic to flocking should first put the swab on the sampling part and gently perform the allergy test before sampling.
use. The swab can only be used once. Be sure to check whether the package is damaged before use. If it is damaged, remember not to use it. Please contact the dealer or manufacturer in time to let it go back and forth. If it is in use If you have allergies, please stop using it immediately. 30 minutes before use, remember not to eat, drink, or smoke or drink, so as not to affect the sampling operation. Please dispose of the discarded swabs in accordance with the laws of your region.
