A member asked:
Got a tb intradermal test. arm still has a little red circle 6 days later and feels a little bruised even though test was negative. is this normal?
A doctor has provided 1 answer
Can be: This prolonged discoloration after tb skin testing is not unusual and was due to trauma to the skin and capillaries at the injection site and may last several more days or so for the blood breakdown pigments to be absorbed.
