Why need to do a test for Mantoux?

 This is a base diagnosis method for tuberculosis in children's. Test ever year repeating and not depending on from last result or for 2 times/year, if for children by reason not done BCG AND organism not saved against Koch stick. And test evaluating in a three days after her doing, and contours of red spot is hyperaemia or  button infiltrate are ideal always circle, thus doctors measuring result on mm, keeping ruler for hand perpendicularly a axis. 

Reaction is negative,if on the third day on the skin are nothing staying as swelling and redness. And meaning, that vaccination done in maternity hospital a not protecting baby, thus again doing BCG.Doubtable  reaction is small redness without a button and on 2-4 mm infiltration, and here is not say,as  baby for sure saving against tuberculosis or not , and on controversial cases a test Mantoux repeating in 2-4 weeks, and do not to  do  her very often , thus you can getting false positive result.

Positive reaction IS visible infiltrate on 5 mm diameter, not worry, within a close year you are not in risk for tuberculosis. 

Hyperergic reaction, excessive , as button are sizes on 10-17 mm and more, and here needing consultation getting in physiatrist, and very alarming,that is happing a calling virage or turn  for tuberculin tests as on a last reaction was been negative, or  doubtful , and positive reaction is on the face, and tie this is with tuberculosis infection, and infection this a not disease, and importance here is importance do not allow developing tuberculosis, thus doctor prescribing antibiotics and other remedies,which are stops stick Koch on the far frontiers for organism. And test Mantoux a never doing for two times in row on the one hand. And on the even years her checking on the right, and on the odd are left pre shoulder, thus immunologic cells memory ability to rise reaction and provoke wrong result. And a few parents are sure, that in allergy this test not to do, reaction always is positive or hypergeric  And on a real time children's with allergy are less,as you think, just 7 percents, and if in doctors are suspicions having ,that positive result happening of allergy, thus test repeats in 4-6 weeks.If reaction true decreased , thus of course allergy here entered.
