I make different vaccinations for each baby. In the first year of life, more vaccines are administered than in subsequent ones. Also, after this period, the child begins to conduct a Mantoux test. It is about her that will be discussed in this article. You will find out how much it is impossible to wet Mantoux, and whether such a ban is needed at all. Also find out what myths are associated with this reaction.
Why can not wet Mantoux?
How much should a child not be wet with Mantoux and why? This is the question that many doctors hear in their offices. This statement came to us from ancient times. Then a tuberculin test was applied directly to the scratched area of the skin. At the same time, doctors categorically forbade contact with any liquid until the reaction was checked. Otherwise, the result could be invalid or false negative. Scratched skin could heal for a very long time, and the applied substance could simply be washed off with water. That is why such an impact on the treated area was strictly prohibited.
Mantoux vaccination: how much can not be wet?
When applying a tuberculin test, doctors forbade contact with any liquids in the designated area for up to three days. Many laboratory assistants believe that it is possible to remove the reaction that has arisen already on the second day after applying the substance, but it is customary to adhere to a three-day break. Most often, a Mantoux test is done at the very beginning of the working week. This allows you to evaluate the result at the end of this period.
How many days can not be wet Mantoux: myth and reality
Currently, the Mantoux test is carried out by subcutaneous administration of the drug. Despite this, many doctors have the only and irrefutable opinion that the vaccine should not be exposed to any liquid. "How much can not wet Mantoux?" - inexperienced parents ask. Doctors give a clear answer to this question: "Before checking the reaction." Is this really the case?
To the question of how much Mantoux cannot be wetted, experienced specialists cannot give an intelligible answer. This happens only because it is possible to apply fluid to the vaccine. Due to the fact that in our time a tuberculin test is injected directly under the skin, water cannot get on it and disrupt the reaction. In this case, how much can not be wet Mantoux?
Doctors say that it’s not worth immediately after the introduction of the sample to go specifically and put your hand under water. A drop of liquid can enter through a prolonged puncture and affect the reaction of the sample. But it is worth noting that after just one hour, the hole is clogged with clotted blood and does not allow various fluids to penetrate inside. It is proved that such a process occurs much earlier. However, doctors are reinsured and ask their parents to ensure that their child does not wet the vaccine in the next hour.
Additional Information
In addition to water, many factors can affect the reaction. So, the place of introduction of the Mantoux test can not be scratched, rubbed, and even less punctured. Otherwise, the reaction may be false positive. In this case, doctors prescribe appropriate treatment, which will not bring any benefit to a healthy body. Also, before conducting a Mantoux, it is worth considering the timing of vaccination. The reaction may be affected by a previous vaccination. Especially if live bacteria and microorganisms were used.
Summary and conclusion
Now you are well aware of how much Mantoux cannot be wetted to a child or teenager. When conducting a test, you should talk with your pediatrician and find out all the details of this test. An experienced specialist will tell you about the exact time at which it is impossible to influence the injection site with various fluids. It is also necessary to remember that when a doctor allows you to wet a Mantoux test, this does not mean that you need to take a hot bath or visit a bath. Refuse in the coming days from such procedures. Give preference to a light soul. Only in this case will the reaction be as accurate and reliable as possible.
Get all vaccinations on time. The Mantoux test is carried out annually, at about the same time. The reaction is removed three days after administration of the drug.
