How To Treat A Red Spot Of 1cm At The Site Of Injection For Mantoux Test?

hello, i have undergone the mantoux test about 30 hours ago and at the site where I was injected, only a red spot is seen. although it is light in color as if I've been bitten by a mosquito. the diameter of the red spot on my arm is about 1cm. does that mean I am mantoux positive?

Hello.. Welcome to HCM.

I am Dr Jigar(ID Specialist).

First of all mantoux test is tuberculin sensitivity test which tell whether your body is prepared to mount immune response against tuberculosis bacteria.

After giving injection results are read only after 48 hours and maximum upto 72 hours.

Development of Redness is very common and is not counted in result. Only diameter of induration is considered. So do not panic redness will fade after few days, just go to your doctor at 48 hours and then ask for interpretation.

I hope this will help you. Give your valuable feedback.

Regards.
