Introduction and function of throat swab

Introduction and function of throat swab

Throat swab is a swab used to check whether the throat is diseased and for throat sampling. It can be said to be a detection method to understand the patient’s condition,

oral mucosa and pharynx infection. Because the pharynx is more susceptible to disease caused by infection caused by external bacteria when the body’s body or local resistance is reduced,

so when we seek medical treatment,

doctors need to collect some cells or viruses for observation to understand the patient’s disease Happening.

In appearance, our throat swab should be straight, neat, smooth, uniform in color,

free of burrs, mildew, scars, scratches, cracks and other defects. As a qualified swab, it should be very good.

Clean, odorless, and soft to the touch, without maculas, stains, or foreign objects.

In terms of performance, the swab should be able to withstand 4N static pressure perpendicular to the axial direction for 15 seconds without permanent deformation or breaking.

The breaking force of the depression at the sampling tip should be no less than 2N.

When using a throat swab, be aware that the flocking has a very light tingling sensation on the skin,

so before use, people who are allergic to flocking should first place the swab

on the sampling part and gently perform an allergy test Later,

it is used for sampling.

The role of transport medium

The role of transport medium

The transport medium is a medium used for the collection, transportation and preservation of pathogenic bacteria or microbial specimens, including liquid and solid types.

Principle of Inspection

Different formulas used in different types of transport media can improve and increase the viability of the corresponding microorganisms in the specimens, so as to facilitate the short-term preservation of the specimens during transportation.

Main ingredients

The main ingredients are formulate with solvents such as sodium chloride, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, agar, and calcium chloride.

characteristic

  1. Almost all cells are preserve in morphology, structure and number, and specimens can be preserve for 6 months at room temperature.
  2. The remaining cells can be directly teste for HPV, DNA, chlamydia, gonorrhea and immunochemical tissue tests.
  3. Eliminate most germs and microbial activity within 15 minutes. Avoid possible harm to medical staff.

Instructions

  1. Before sampling, mark the relevant sample information on the label of the sampling tube.
  2. Sampling with the corresponding sampling swab.
  3. After sampling, quickly put the swab into the sampling tube.
  4. Break the swab at the breaking point of the swab and discard the tail.
  5. Tighten the tube cover tightly. Then put the sampling tube containing the sample into the biosafety bag and send it for inspection in time.

Throat swabs are generally used to check for what disease

Throat swabs are generally use to check for what disease

If we are sick, it is very important to seek medical treatment in time. When we arrive at the hospital, in addition to listening to our description of the medical history, the doctor also needs to perform corresponding examinations. Only through medical history consultation and laboratory examinations can we diagnose the disease and its medication plan.

When we go to the hospital for physical examination, the items include blood test, urine test, stool test, etc. What we are going to mention today is a test call throat swab culture. I believe that this kind of test is familiar to everyone this year, and everyone should have been expose to it. So what kind of disease do throat swabs usually check? Next, I will give you a specific description of this issue.

Throat swab inspection is to take secretions from the throat, conduct bacterial culture, and then conduct a drug susceptibility test based on the infected bacteria. The results of the throat swab examination can provide an important basis for the accurate medication of the clinician.

Throat swabs are generally used to check upper respiratory diseases, such as acute suppurative tonsillitis, acute pharyngitis, diphtheria and other respiratory diseases.

After taking out the secretions and performing corresponding examinations,

it can be known which bacteria are the main infections of the patient. Finally, the doctor will use the susceptibility results of the cultur bacteria as an important basis for clinical medication.

Note that when undergoing a throat swab examination, there may be mild neural reflexes, so everyone must hold back.

What are the characteristics of disposable sampling swabs

What are the characteristics of disposable sampling swabs

The disposable sampling swab adopts the flocking method of spray and electrostatic charge, so that millions of nylon microfibers are vertically and evenly attached to the handle end. The capillary action between the nylon fiber bundles is conducive to the strong hydraulic absorption of liquid samples.

Compared with traditional twisted cotton swabs, most of the samples collected by traditional twisted cotton swabs are captured in the fiber matrix at the end of the cotton swab, and only a small amount of 20-30% of the sample can be released. The flocking cotton swab can retain the microbial sample on the fiber surface, and the rapid elution is greater than 95% of the original sample, which can easily improve the detection sensitivity.

Sampling swabs are certified to be free of ribonuclease (RNAse), deoxynucleic acid (DNAse) and human deoxyribonucleic acid, and no PCR inhibitors.

Features

1.It has extraordinary water absorption capacity, which can increase the number of specimens collected on its watch from 20% of traditional sampling swabs to 60%.

2.The release rate of collected specimens exceeds 90%, thus ensuring the high reliability of the results.

3.There is a unique breakable design on the plastic rod, which is convenient for specimen transportation.

4.Different preservation solutions are selected for different types of specimens.

5.It is made of non-inhibitory DNA amplification materials, and it has been verified that it can be directly amplified by PCR, eliminating the need for extraction.

6.It adopts single and independent packaging to avoid pollution.

7.Strict process conditions, no DNase and amplifiable human DNA.

8.The tube body is transparent, and the inspection materials are intuitively visible.

9.The unique casing design ensures the air circulation in the casing, prevents the sample material from being mildewed due to the humid and sealed environment, and avoids magazine pollution in the outside air, which will affect the quality of the inspection.

What to pay attention to when sampling nasal swabs

What to pay attention to when sampling nasal swabs

The following are the things we need to pay attention to when we go for a nasal swab.

Precautions for samplers:

1. The sampler stands on the side of the subject and takes the sample.

2.Subjects were asked to pull down the mask to reveal only their nostrils.

If the subject has a sneezing reflex, the subject can block it with an elbow or a tissue. This will not be directly in front of the subject and can reduce the risk of exposure.

3. If the subjects 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 may easily induce sneezing. It is recommended to use an oropharyngeal swab for sampling.

5. Remember to wear a protective mask/face screen. For individuals who are highly suspecte or basically diagnos, or have severe coughs and hiccups, they should wear protective clothing.

6. After sampling, it is necessary to change gloves, perform hand hygiene and disinfection, and spray disinfectant on the contact area.

Precautions for the subject to do nasal swabs:

1. Do not take antibiotics for a few days before using the nasal swab. This will affect the test results.

2. In the few hours before the nasal swab is wipe, do not use disinfectant mouthwash or apply the topical area.

3. You cannot eat, smoke or drink for several hours before the nasal swab is wipe.

How to do a stool test

How wo do a stool test

When we go to the hospital to check the body, the doctor may let us check the stool, let us know about it next.

Clinical sampling charecteristics that need to be collected from stool specimens:

The patient has  abdominal pain, diarrhea (watery stool, pus and blood in the stool), or accompanied by fever; routine stool examination is abnormal, it is recommend to collect stool specimens for bacterial culture.

Specimen collection and requirements:

The patient has abdominal pain, diarrhea (watery stool, pus and blood in the stool), or accompanied by fever; routine stool examination is abnormal, it is recommend to collect stool specimens for bacterial culture.

Specimen collection and requirements

As far as possible, the collection of specimens should be collecte in a wide-mouth toilet box and sealed with a lid before applying antimicrobial treatment.

However, considering Campylobacter jejuni, Campylobacter sanguis agar medium is requir. Not only does Clostridium difficile need to survive in an anaerobic environment, it is also recommend to collect and inoculate specimens at the bedside, and then immediately put the inoculate specimens in an anaerobic bag and sent it to the laboratory.

Collection method:

(1) Natural defecation method

After the patient has a natural bowel movement in a dry and clean potty (avoid sitting or squatting),

Not only take 2~3g of feces with feces, blood and mucus (1~3ml of flocculent liquid is used as feces), but also put it in a sterile urinal box for inspection.

If there is no mucus, pus, or blood, collect more spots on the stool for examination.

(2) Rectal swab method (patients or infants who have difficulty defecation)

Not only should the area around the anus be washed with soapy water,

but also a sampling cotton swab dipped in sterile saline should be inserted into the anus 4 to 5 cm (children 2 to 3 cm).

The sampling swab is in contact with the surface of the rectal mucosa.

Rotate the swab gently, and stool can be clearly seen on the swab.

Not only should the sampling cotton swab with the stool sample be inserte into the virus sampling tube,but also the cotton swab should be broke near the breaking point,

the cap of the tube should be tightened, a

nd the inspection should be carry out immediately. (Repeat collection of specimens can increase the positive detection rate)

Labels and application forms:

(1)The application form must not only include the patient’s name, medical record number,

collection date, but also write down the time, diagnosis, and related travel history records.

(2)Specimen identification not only requires a unique identification number or bar code,but the label on the specimen also includes the patient’s name, medical record number, collection time, etc.

(3)Fresh specimens submitted for inspection should report the characteristics of feces,

and it should be noted when there is blood on the surface of the specimen or in the specimen.

In fact, stool testing is very useful in clinical practice. It can not only initially understand whether the digestive system has inflammation, hemorrhage, parasitic infection, malignant tumors, etc., but also indirectly determine the functions of the gastrointestinal, pancreas, liver, and gallbladder.

Tips for using oropharyngeal swabs

Tips for using oropharyngeal swabs

The oropharyngeal swab is a sampling tool used to extract mucosal cells and secretions from the oropharynx.

The sampling method requires the use of sterile throat swabs and other items to penetrate deep into the pharynx,

Not only go through the base of the tongue to reach the posterior pharyngeal wall, tonsil recesses, side walls, etc.,

but also wipe left and right 3 to 5 times, and then gently remove the cotton swab.

Then put the swab stained with mucosal cells and secretions into the virus sampling tube and send it for inspection in time.

Instructions

1.Ask the patient to sit down, not only let the patient tilt their head back and open their mouth, but also let the patient make an “Ah~” sound.

2.The sampler can fix the tongue with a tongue depressor, and use an oropharyngeal swab

to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, side wall, etc.

3.Wipe 3 to 5 times repeatedly to collect mucosal cells.https://www.chenyanglobal.com/

4.Not only must gently remove the cotton swab, but also avoid contact with the tongue, pituitary gland, oral mucosa and saliva.

5.Put the sampling swab and the sample vertically into the virus sampling tube,

Not only do you have to break the swab where it breaks, but also discard the end of the swab.

6.Tighten the cap of the tube,

put it in a biosafety bag, and send it for inspection in time.

Annotation

1.For purulent pharyngitis, the bacterial culture of oropharyngeal swabs is mainly

used for screening group A β-hemolytic streptococcus and hemolytic cryptobacteria.

2.When testing Neisseria gonorrhoeae in oropharyngeal swabs, the clinic needs to inform the laboratory in advance.

3.For pediatric patients, Haemophilus influenzae should  reported routinely.

4.Under normal circumstances, not only cannot the throat swab sample be used alone to diagnose upper respiratory tract infections, but it must also be used in combination with a nasopharyngeal swab

Suction to increase the detection rate of pathogens of respiratory tract infections.
