Mantoux?

I had my mantaux done today. I know they read it between 48-72 hours, but what if it reacts right away? Does it ever go back down before 48 hours indicating a negative?

I've worked long term care for almost 5 years. I had yearly mantoux's (sp?) and never had ANYthing whatsoever. Usually we couldn't even find the injection spot.

Today though...I got my mantoux at 7:15. At 6:30 this evening I just happened to look down and notice a circle on my arm. I don't have a ruler at home..but it's slightly larger than a dime.

What are your thoughts? Could it still be negative...or am I definately looking at a chest X-Ray?

It is probably caused by the way it was injected. Yes the redness and swelling can go down in 48 hrs.

I had one done that raised a red bump. It was due to the way she gave me the shot. She kinda twisted the needle.

Hope this helps!!

thanks. I guess I'll just wait and see. Her method seemed perfect. It didn't hurt at all, she got just under the skin..and I had a perfect bubble. Time will tell I guess. Funny how something I never really thought about can cause worry though when it's personal.

Mine always reacts right away. It never indurates though. It looks positive... but by the time 72 hours comes its ok. I have a questionable preservative allergy because I dont react to ALL types of tuberculin.

The one I had a year after graduation, wasn't fun. I mistook a little eensy weensy bump of a mole that I never paid attention to, for induration, as did the nurse I worked with who was gonna read it, so then I had to take a little trip to employee health. The nurse there got a good laugh out of it and I made a note to have the silly thing done on my other arm next time so that wouldn't happen.

ok- well- update. All reaction is now gone. You can hardly tell where the injection was to begin with....and it'll be 48 hours tomorrow. Thanks for the responses.

Hey all!

I know this thread is old, but wanted to add a new question to it... How common is it to have a bruise at the injection site after a Mantoux test. (NOT a reaction, just a pretty, purple hematoma) I've started getting them the last couple times, never seen it before on either myself or others. Just wondering if others have seen this, or if I'm just a freak of nature. (Like this is the defining factor for that benchmark... :rotfl: ) Thanks for any input!

MNmom,

This is the sort of thing we here at allnurses.com can't tell you. That's considered medical advice and we can't give it. We do wish you well and encourage you to talk to your primary care provider about it. Thank you.
