Should I give my child mantu if he has a runny nose?

For what purpose do doctors administer a tuberculin test?

Mantoux is a test that is necessary to determine the causative agent of tuberculosis. A subcutaneous injection is not considered a vaccination and is used for timely detection of Koch's bacillus.

Tuberculin contains dead bacteria that enter the child’s body. After administration of the drug, a button forms at the injection site, which enlarges in the presence of a pathogen.

The tuberculin test performs several functions:

1. Mantoux vaccination serves to identify people who are carriers of Koch's bacillus. The immunological reaction appears only 24-72 hours after administration of the drug.
2. Thanks to the procedure, it is possible to confirm the presence of an infection that is in the active phase.

General information about the sample

Mantu is over sixty years old. Thanks to this test, the doctor detects the infection in time and begins treatment. The test is not a vaccination, but it makes it possible to understand whether there is an infection in the body. Mantoux allows you to detect tuberculosis. The injection solution is injected under the skin, into the middle part of the forearm. A tuberculin test is needed for adults and children. Thanks to it, it is possible to determine the response of the immune system to tuberculin. To obtain a reliable result, several procedures are required at time intervals.

Mantoux is necessary for children. Adults often forget to take a test, but they need it too. Patients are also interested in: is it harmful to make mantu when you have a runny nose? The test is not harmful to health. Some patients are wary of phenol, which is in the serum. This component is believed to have a toxic effect if ingested. However, phenol is harmful if it enters the body in large quantities. The serum that is used for mantu contains little phenol and does not affect the immune system. Phenol is a metabolite formed in tissues. When entering the blood, it decomposes in the structures of the liver. This component is excreted naturally.

The mantoux reaction is carried out once a year. If carried out more often, the child’s body will become sensitive to tuberculin, resulting in a false positive reaction. The body will not develop immunity even if the pathogens of tuberculosis are overtaken. Mantoux can lead to complications. They occur when the body mounts an excessive immune response to tuberculin. A hyperergic reaction is manifested by inflammation of the skin at the site of injection of the serum.

If the body gives a hyperergic response, then there is a tuberculosis infection. There are cases when the immune system perceives tuberculin as an allergen. Then signs of hypersensitivity appear, the injection site turns red and itches. It is necessary to prohibit the child from scratching the injection site, otherwise there will be a risk of a hyperergic reaction. The body can react acutely to tuberculin. In this case, the temperature rises. If a cough appears after the test, its causes are trivial and are not related to the administration of the serum.

Reaction to the mantu test

Negative indicates that there is no overt or latent TB infection. If the test was carried out in the next 5 years and the reaction is negative, this may indicate that the body is not able to remember the causative agents of the disease. A negative reaction indicates that the person is not infected with tuberculosis, but the immune system does not respond to tuberculin, which was previously administered. A positive reaction depends on the size of the scar on the skin remaining after the test.

There is a “Mantoux Turn” - this is a reaction in which the response to tuberculin is enhanced compared to the reactions of previous years. A turn is observed if negative or doubtful reactions become positive. In such situations, the papule reaches a size of 1 cm and persists for more than two years.

How does the Mantoux test affect babies with a runny nose?

Doctors do not have a clear opinion regarding the issue of performing Mantoux for a runny nose. Some experts believe that subcutaneous administration of the drug is not capable of having a noticeable effect on the state of the immune system.

When administered subcutaneously, the reagents are localized in a specific location. Under the influence of tuberculin, a certain reaction occurs in the baby, which makes it possible to identify the fact of carriage. Most parents refuse the procedure if the baby has a runny nose.

The following diseases may be reasons for refusing Mantoux:

1. The baby has symptoms of bacterial or viral rhinitis.
2. The child suffers from catarrhal or allergic rhinitis in a chronic form.
3. The baby began to develop ozena, an unpleasant disease that is accompanied by the discharge of pus. The administration of tuberculin can lead to a deterioration in the child’s condition.
4. A severe cough indicates damage to the nasopharynx by dangerous bacteria or viruses. In this condition, the baby needs drug treatment.

Doctors evaluate the state of the child's immune system. After ARVI, the baby should not be given Mantu for a month.

Children suffering from pneumonia require long-term treatment. In this case, the procedure will have to be postponed for at least 2 months. To make a decision, a detailed blood test may be required.

Is it worth doing a test if you have a cold?

Rhinitis is a symptom of a cold. If an antiviral drug is used to treat a disease, testing is prohibited. Colds can occur due to exposure to viruses. Antiviral medications strengthen the immune system and promote the production of interferon. If a patient takes manta while suffering from a cold, the body reacts strongly to the vaccine. A contraindication to the test is elevated temperature. If it reaches 37.5, the body's defenses are mobilized, resulting in an enhanced response from the immune system. It happens that tuberculin itself leads to an increase in temperature.

Is it possible to make mantu for a runny nose or if a child is coughing? First of all, you need to establish a diagnosis. If there are all the signs of tuberculosis, a test is necessary. In most cases, cough occurs against the background of respiratory diseases. Cough is a symptom of flu and bacterial sore throat. If rhinitis occurs after mantoux, the cause is hypothermia of the body, less often - an allergy to something. Tuberculin contains inactive fragments of tuberculosis bacteria. The drug does not contain components that could lead to rhinitis. A runny nose after mantoux is caused by viral pathogens.

What effect does a runny nose have on test results?

Colds complicate the examination process. An increase in the size of a papule does not always indicate the presence of Koch's bacillus. The body of a child with symptoms of a runny nose is forced to fight pathogenic microorganisms.

When examining a patient, doctors receive a distorted picture, since inflammatory processes cause swelling and redness at the injection site.

Several factors can be identified that influence the reliability of the results obtained.

1. The state of the immune system depends on the presence of infectious diseases.
2. It is necessary to properly care for the sample site for 3 days.

Does it happen that a child gets sick after Mantoux?

If a child gets sick after Mantoux, most likely, a viral infection was already in his body, and the introduction of tuberculin simply became a “impetus” for its progression. The causes of the development of a disease with symptoms characteristic of a cold are:

• too weakened immunity - even if he could restrain the viruses in the body, then after the introduction of mycobacteria extract (tuberculin composition) he directed all his strength to fight them;
• the child’s diet is “poor”, it does not contain enough vitamins and microelements;
• the daily routine, its schedule is incorrect - for example, not enough time is allocated for night sleep, the bedtime/wake-up schedule is messed up, and so on;
• teething;
• use of an expired drug.

Only a doctor can determine exactly what is causing the child’s illness after the Mantoux test.

We recommend reading the article about what Mantoux vaccination is. From it you will learn about the composition of the drug, the method of performing the Mantoux test, why it is needed, and whether it is possible to refuse Mantoux. And here is more information about the age at which Mantoux is made.

Symptoms of the disease

The disease after Mantoux proceeds in a standard manner, its symptoms are completely identical to a cold:

• cough;
• runny nose;
• headaches (unexpressed);
• sore throat when swallowing;
• elevated body temperature.

The last indicated symptom deserves special attention, because hyperthermia does not pose a danger to the health and life of the child only if:

• it appeared not on the day of tuberculin administration, but a day later;
• there is itching and redness at the injection site;
• the size of the Mantoux spot is within one and a half centimeters.

In this case, doctors talk about a hyperergic reaction of the body, which indicates the absence of Koch bacilli in the body.

Cough, runny nose and fever

This combination of symptoms is possible if there is a respiratory infection virus in the child’s body before tuberculin is administered. Usually the child's condition improves 3-5 days after Mantoux, but parents should still consult a doctor and get prescriptions for specific medications.

Often, after a tuberculin test, the child is only bothered by a runny nose, in which case doctors recommend using Derinat drops or spray for treatment. This drug has the following characteristics:

• strengthens general and local immunity;
• has a detrimental effect on pathogenic microorganisms;
• prevents the spread of viruses throughout the body;
• restores the nasal mucosa.

Does this affect the test result?

In most cases, the disease does not affect the test result, but sometimes doctors may note the formation of a compaction at the site of tuberculin injection and severe (critical) redness. Such signs indicate a positive result of the Mantoux test.

The doctor must collect an anamnesis from the parents regarding the presence/absence of symptoms of a classic cold and, based on the information received, make a choice in favor of conducting an additional test.

Mandatory examination by a pediatrician

What to do and how to treat a child

If the child is clearly ill after the Mantoux test, then experts recommend doing the following:

• if the temperature rises to 37.5 degrees (subfebrile), do not take any action, do not give the baby antipyretic drugs;
• at higher thermometer readings, you can give the usual medications with an antipyretic effect;
• if there is redness and itching at the injection site, you can take an antihistamine (Tavegil, Diazolin, Suprastin);

Diazolin Tavegil Suprastin

• cough is treated with herbal decoctions (if there is no allergy to such drugs) or inhalation procedures (strictly at normal body temperature);
• It is better to get rid of a runny nose and nasal congestion by rinsing the nasal passages and sinuses with special solutions or inhalations.

Standard cold symptoms after the Mantoux test do not require medical intervention, but there are a number of signs that make it necessary to immediately seek qualified medical help:

• digestive system disorder – nausea/vomiting, diarrhea, intestinal colic, increased gas formation;
• severe headaches, dizziness;
• “spreading” swelling of the soft tissues of the face and limbs;
• difficulty breathing - wheezing, shortness of breath, whistling exhalations (this indicates swelling of the larynx);
• rashes of various types on the skin.

You should also call a doctor if your body temperature is above 38 degrees, your readings are rising, and antipyretic drugs do not help.

Komarovsky's advice

Often parents do not know the purpose of the tuberculin test. They perceive this procedure as an inoculation or vaccination. The main task of Mantoux is to timely identify the fact of carriage.

The dose of tuberculin present in the sample is so small that it cannot have a detrimental effect on the child’s immune system. Komarovsky recommends giving up Mantoux if your baby has a severe cough and runny nose.

During the process of reproduction, harmful bacteria release toxins. The child’s immune system is forced to respond to the penetration of pathogenic microorganisms. To conduct the examination, the consent of the baby's parents is required. Komarovsky does not recommend making Mantu if quarantine has been introduced at school or kindergarten. The reaction to the drug depends not only on the physiological characteristics of the child.

It is necessary to properly care for the injection site. After introducing the reagents under the baby’s skin, tuberculin reacts with the immune system. The procedure allows you to identify antibodies that are produced in the body.

Tuberculin contains neutralized segments of tuberculosis bacteria. Most doctors are convinced that there is no clear connection between the Mantoux test and a runny nose.

The tuberculin test does not pose a danger to the baby, provided that precautions are followed. Mantu should not be given to children who are infected with a bacterial or viral infection. During this period, the body's defenses are under increased stress. The introduction of a tuberculin composition can only complicate the baby’s condition.

Advice! The immunological test can be started only after complete recovery.

Runny nose

The mucus that is produced in the nasal passages prevents the penetration of pathogenic microorganisms and drying out of the cavity. Abundant secretion of mucous substance and snot indicates the presence of an inflammatory process in the nasopharynx, which is a runny nose.

It can occur independently, for example, due to hypothermia, or be the result of an allergic reaction, or it can act as a concomitant sign of a viral disease.

Do not forget that babies have not yet fully formed internal structures of their nose. Narrow nasal passages impede the intensive outflow of mucus.

Prolonged runny nose can cause complications.

It is very important that with the onset of rhinitis, parents immediately consult a doctor. Only a specialist can correctly understand the cause of this disease and prescribe appropriate treatment.

How long after illness can Mantoux be done?

If the baby has suffered from ARVI, you will have to wait for a month. The Mantoux test cannot be performed immediately after an illness. Premature administration of the tuberculin drug will distort the results. Residual symptoms of a runny nose are not an obstacle to the procedure.

Important! Only the attending physician can determine the exact date of the examination. Typically, the duration of recovery after an acute respiratory infection is 1 month.

What points should you pay attention to?

3 days after the procedure, doctors evaluate the Mantoux reaction. Specialists measure the diameter of the infiltrate that forms at the injection site. To identify the presence of the causative agent of tuberculosis, you can use the table.

Mantoux test specification

The Mantoux test is performed once a year to examine the child population for sensitivity to tuberculosis bacteria. Medicine considers this diagnostic method to be the most reliable. Its necessity is:

• initial determination of the presence of pathogens;
• substantiation of an infection that already exists in the body;
• identify people who have the status of carriers of infection without signs of its manifestation;
• conducting the selection of children who need to receive repeated preventive BCG vaccination;
• note the number of patients with a positive result (papule with a diameter of six or more millimeters).

It is carried out as an intradermal injection with the introduction of tuberculin. The general condition does not change after this manipulation. Body temperature remains within normal limits. It is the injection site with a possible reaction that is subsequently assessed on the third day after administration.

The results are divided into several valid options:

• negative, the size of the seal does not exceed one millimeter;
• doubtful if the boundaries of the papule reach four millimeters;
• a positive result when the result is five or more millimeters;
• a pronounced infiltrate with a diameter of more than sixteen millimeters, after which it is necessary to carry out an auxiliary additional examination of the child.
