How does Diaskintest differ from the Mantoux reaction?
Due to the fact that the drug DIASKINTEST contains proteins that cause an immune response only to the presence of pathogenic (capable of causing disease) mycobacterium tuberculosis, the test has a higher sensitivity compared to the Mantoux river (the ability to detect infection in those who actually have it ) and, most importantly, higher specificity (the ability to give a negative reaction in those who do not have an infection).
Mantoux, Diaskintest test, Quantiferon test or T.SPOT? How do the methods for diagnosing tuberculosis differ and which one to choose?
What you can and cannot eat after vaccination
After the Diaskintest injection, strict rules regarding the choice of food are not established. You can eat and drink everything that is usually included in the menu. You shouldn’t limit yourself; you can eat sweets and enjoy your favorite foods. Although, of course, you shouldn’t eat desserts alone either. A reasonable approach to nutrition after an injection is to exclude foods that can trigger an allergic reaction. In addition, foods that are highly allergenic should be removed from the child’s diet:
- oranges, tangerines and other citrus fruits;
- chocolate;
- red apples;
- nuts.
You should not feed your baby new exotic foods; they can cause an unpredictable reaction. The menu should remain the same as the child is accustomed to.
Other restrictions
Doctors do not recommend actively engaging in sports after Diaskintest, because increased physical activity causes profuse sweating, and sweat is an irritating factor that can cause a skin reaction in the form of redness and itching. The result in this case may be false positive.
After Diaskintest, you should not expose your body to sudden temperature changes: take long walks in the cold in winter or stay in the sun for a long time in summer. All this can have a distorting effect and lead to “blurred” results.
It is better to give up alcohol within 72 hours, as alcohol can change the severity of the reaction, and the result may also be false.
Parent Questions
Is it possible to do Diaskintest if allergies worsen?
Yes, but against the background of desensitizing therapy (5 days before and 2 days after the test).
Is it possible to eat sweets while on Diaskintest?
Can. But if you know that sweets can provoke an exacerbation of skin allergies, then it is better not to give them to your child.
Is it possible to do Diaskintest with a runny nose?
Yes, if it is not accompanied by an increase in temperature.
Is it possible to do Diaskintest immediately after an illness?
You should wait 2-3 days after the temperature has returned to normal. Residual runny nose and cough are not a contraindication and will not affect the results of Diaskintest.
Can Diaskintest provoke tuberculosis?
Preparations for Diaskintest are obtained from genetically modified strains of Escherichia coli, which in no case can cause the development of tuberculosis. Diaskintest is usually very well tolerated, only in rare cases there is a short-term and slight increase in temperature, mild headache and malaise.
Is it possible to wet Diaskintest and is it possible to go to the pool after Diaskintest?
Yes, you can wet Diaskintest and wash yourself. But it is still better to avoid exposure to chemical irritants (shampoos, reagents in the pool). Also try to prevent the child from scratching the sample.
What should a child not do after Diaskintest?
You should not rub or scratch the injection site, or apply any chemicals (iodine, brilliant green, hydrogen peroxide, creams) to it; for the same reason, you should not visit the pool. Everything else (walking, swimming, eating everything that does not cause an allergic reaction in your child) is possible.
What to do if a purple bruise remains after Diaskintest?
Don't worry ahead of time. Firstly, the bruise may completely disappear by the time of the test. Secondly, the size of the bruise also matters. During the test, the doctor will measure your reaction to the test and give you precise instructions on what to do next.
Can there be a fever after Diaskintest?
Yes, elevated temperature after Diaskintest in children is quite possible. Usually the discomfort does not last long and goes away on its own without treatment. What to do if you have a high temperature after Diaskintest? Most likely, it is associated not with the tests being carried out, but with ARVI or another disease that coincided with the time of Diaskintest.
Is it possible to get vaccinated after Diaskintest?
The interval between vaccinations (including BCG) and Diaskintest should be at least 1 month. If the Diaskintest result is negative, you can start vaccination immediately after the test.
Is it possible to do Diaskintest after Mantoux?
Yes, you can do Diaskintest after the Mantoux test.
Is it possible to refuse Diaskintest?
Yes, you can refuse Diaskintest and replace it with other tests for tuberculosis, such as the Mantoux test, quantiferon test or T-spot, as well as fluorography for children 15-17 years old. We do not advise you to refuse tuberculosis tests as such: the epidemic situation in Russia remains tense.
You can always ask all your questions and consult about Diaskintest in your particular case with our pediatricians by phone: +7 812 331 00 00.
What happens if you wet the injection site?
Moisture getting into the injection site will not cause much harm, but the effect of water on the new drug has not yet been thoroughly studied. It is better to prevent the penetration of foreign bacteria into an unhealed wound, especially on the first day after the procedure, when it has not yet healed.
What to do if Diaskintest gets wet
If water does get into the injection site, there is no need to panic. You just need to carefully blot the visible moisture with a napkin, without pressing, and do this until it dries completely. Under no circumstances should the papule be rubbed with a material with a rigid structure, covered with a plaster or tied with a bandage. If you get wet, you must tell your doctor about it.
Diaskintest and beer
Diaskintest and beer are incompatible. If a person has been tested, it is better not to drink alcoholic beverages.
When taken in large quantities, the immune function is suppressed and health worsens. Therefore, the sample may be unreliable. But the reaction is typical for patients who abuse beer and other alcohol.
A repeat test will be required, which can only be done 6 months after the previous test. During this time, the bacteria will spread throughout the body, causing damage to the lungs, kidneys and other organs.
If a person drinks a small amount of the drink, no negative effect will occur.

When and why is the test done?
The widespread replacement of the tuberculin test has not yet occurred. Therefore, all children and adolescents undergo tuberculin diagnostics using the Mantoux test. Children with a positive reaction to the test are sent to a TB specialist to determine the cause of this reaction. In this case, the Diaskintest test is recommended.
A positive reaction indicates the presence of Mycobacterium tuberculosis in the child’s body.
A mandatory computed tomography scan of the respiratory organs is prescribed. If the study does not confirm the pathology, the child is prescribed preventive therapy with anti-tuberculosis drugs. If a pathology is detected, the child undergoes a course of drug treatment in a hospital setting.
Diaskintest is done on the forearm of either hand. The procedure is similar to any test.
Use for hangover
If you use the drug for a hangover, it is important to remember:
- It is sensitive to acetaldehyde, a breakdown product of alcohol.
- It is not recommended to use if you are feeling unwell or ill.
For a hangover, it is recommended to take the medicine 14 hours after drinking. Also, in case of a hangover, doctors advise taking sorbents along with special diuretics to get rid of unpleasant symptoms.
Testing for the presence of TB pathogens during a hangover may be less accurate.

Is it possible to play sports after Mantoux?
Physical activity can provoke a false positive reaction to the drug. Regular exercise strengthens the child’s immunity, but after the test the intensity of exercise should be reduced. A person playing sports can injure the injection site, which may result in distorted test results.
It is not recommended to engage in exercise that results in excessive sweating and skin irritation.
Sometimes physical activity can cause injuries and the appearance of microcracks at the site of sample insertion. You should not completely give up sports and exercise. After Diaskintest, you can run and ride a bike, do exercises and therapeutic exercises.
Is it possible to wet a tuberculosis test?
Detection of the presence of Koch's bacillus in the body is carried out annually. Testing has always been a mandatory procedure, and only recently have parents been allowed to refuse the test. The older generation is increasingly trying to avoid diagnosis, not fully realizing how serious the consequences can be.
The Mantoux test occupies a leading place among all options for testing for tuberculosis. In case of doubtful or clearly positive reactions, a secondary determination is carried out using Diaskintest. The drug belongs to modern technologies and is more sensitive. After the test, many parents are concerned about the question: what will happen if they accidentally wet the Diaskintest?
How to do the test
The test is prescribed after an unsuccessful Mantoux test - in order to exclude a false positive result. The patient is sent for a consultation with a phthisiatrician at the tuberculosis dispensary, and additional tests are prescribed. If the patient’s response is negative, the test is monitored for a certain period; secondary testing can be scheduled after six months.
During this period, the patient is recommended a regimen and proper nutrition to carry out preventive measures against pulmonary tuberculosis.
General rules for using the test correspond to the tuberculin diagnostic algorithm:
- the injection is placed on the middle third of the forearm;
- the injection is carried out intradermally - using a syringe with a thin needle;
- a slight swelling appears at the injection site;
- The results are assessed after three days.
Diaskintest in adults is performed for the following indications:
- questionable data from fluorography;
- suspicious tests;
- specific symptomatic manifestations are inflammatory processes in the lymph nodes, periodic causeless cough.
The difference between the procedure is the assessment - if a papule is observed at the injection site, then its formation indicates that mycobacterium tuberculosis is present in the patient’s body.
You should evaluate the results correctly and not panic - some citizens may experience an allergic reaction to the composition of the drug. Only a doctor will tell you about a possible risk or existing infection.

Preliminary preparation for Diaskintest consists of identifying existing contraindications:
- presence of an infectious disease;
- exacerbation of chronic pathologies;
- severe allergic reactions;
- various skin diseases;
- epilepsy;
- recent vaccination.
Testing is allowed in old age, during pregnancy and does not have a negative effect on the body.
What not to do after the injection
To prevent false reactions, experts recommend adhering to the following rules:
- doctors recommend refraining from any water procedures for three days - you should not wet Diaskintest in open reservoirs or swimming pools in order to prevent dirt from getting in;
- visiting saunas, steam rooms and baths is prohibited;
- intense physical activity is contraindicated for three days - sweat entering the injection site will cause a false positive result;
- being in direct sunlight or visiting a solarium can change diagnostic indicators;
- long walks during the cold season will also distort the final indicators;
- It is not recommended to rub with a washcloth or scratch the injection site - obsessive itching is a non-standard reaction that indicates an allergy;
- experts advise not to treat the skin with brilliant green, methylene blue, iodine or antiseptic solutions - all third-party substances will distort the final data;
- It is prohibited to apply a plaster or bandage to the injection site, or to use creams or other cosmetics.
What should you not eat after Diskintest? Mandatory restrictions include food products that can provoke allergies - chocolate and products made from it, all types of citrus fruits, nuts.
How to monitor the test correctly
Doctors do not recommend allowing liquid to get into the injection site for a number of reasons:
- pathogens may be present in poorly purified liquid - the condition applies to water from wells and natural sources;
- tap water contains chlorine - the skin reaction is individual and can provoke local allergies;
- detergent or any cosmetic product that gets into the injection point causes irritation.
From the moment of injection until evaluation of the results, you should not wet Diaskintest for three days. If an area of the dermis gets wet, you need to gently blot it with a napkin, without pressing or rubbing.
Is it possible to wet Diaskintest?
Doctors advise reporting contact with water - a specialist will decide whether the manipulation needs to be repeated. Doctors often encounter questions from parents about manipulation:
- Is it possible to wash during Diaskintest? The use of detergents and cosmetics will distort the final data and cause a retake.
- When can you wet your hand? Immediately after assessing the sample, the patient is allowed to return to his usual lifestyle - he is allowed to swim, take a shower or bath.
- Is it possible to wet the vaccine? Accidentally spilled liquid will not cause much harm - if the area is wet, remove any remaining liquid with a soft cloth. Purposefully steaming your hand will distort the results.
- Why can't you get it wet? To prevent the need to repeat the sample.
- The doctor does not listen to my explanations about accidental ingress of water and requires secondary testing? The phthisiatrician has the right to prescribe a test based on questionable test results. Many experts believe that the ingested liquid does not play a big role, especially if the body overreacts to the manipulation.
Checking requires a serious attitude on the part of adults - a child may unintentionally scratch the injection point, apply cream or use soap. To protect your baby from repeated injections, you should follow the pediatrician’s recommendations about unwanted actions.
Use for alcoholism
The drug can be used in the presence of chronic alcoholism. But, due to the fact that ethanol breakdown products interact with the main components of the medication, the test must be carried out 24-30 hours after the last drink.
The drug does not contain tuberculosis pathogens, so it is not dangerous for children or people with low immunity and increased sensitivity to vaccines.
Studies have shown that the medication can be freely used by people suffering from alcoholism if they have not consumed alcoholic beverages.
