Hi, this is Dr Stan, here to help you.Board Certified with 40 years of Patient Care. I will respond with my answer shortly. Thank you.
The pictures and your description are of a negative PPD test. There is no reason to be concerned. I am here to answer any additional questions you may have. Please leave a positive rating of 3-5 stars. This is how I am credited for my response. Thank you.
Yes, the picture is negative as is you description. A positive PPD is raised and at least 15mm in diameter. Your PPD is negative.
the test is to be read at 48 hours, if suspicious it is rechecked at 72 hours. It does not meet the criteria of a positive test.
take a look at this, which is positive.
That is correct.
Your RN is correct. I have tested thousands of patients over the past 40 years and I only need look at the result to determine if it is positive or negative.
