Will accidental contact from poison Ivy affect the hemoglobin level?
Patient: I am a 67-year old male and have just contracted poison ivy from gardening trimming bushes, etc.  I had a recent hemoglobin level of 12.2 and am due to have a repeat blood test.  Will having poison ivy affect my hemoglobin level and is it safe to have the lab test with the poison ivy on my arms.  Normally, the blood is drawn from my hand.  Thank you. Doctor: Hello and thanks for your question.Having poison ivy will not have any effect on your blood tests. Good day to you and I hope the poison ivy clears up soon.
