I was tested 4 years ago and ppd test result is negative. Chest X-ray as well is negative too. When I have my ppd test recently, I feel an induration and measure it, it's 8mm after 3 days. I am so worried about the induration size since I am in Nursing school and could possibly affect my study and future employment. I read many articles about ppd interpretation however it confuses me since many information varries. Some wrote, a little bump is ok, some wrote if less than 5mm is negative and more than 5mm is positive. Some wrote that it will depend on the medical history of a person, others wrote over 10mm will interpret positive. Recently tested for HIV. (Result: Non-Reactive) Got tested for Chest X-ray. (Result: Negative) I dont go through organ transplant. I dont use drugs neither smoke. I am not diabetic and not working in the hospital or nursing home. I am not coughing or loosing weight or excessive sweating at night. I am not in contact with anybody who has TB. Is 8mm NEGATIVE OR POSITIVE? Please advice.

I am taking my pre-requisite for Nursing and PPD test is required. I did my ppd test 4 years ago and it's negative. I also did my chest-xray and it's negative. Now the school requires a new ppd test. I am so worried because I have an induration of 8mm. I read all the articles and books about the interpretation of PPD test though they vary on the information. Some wrote less than 5 is negative and 5 above is positive. However, the induration should also be supported with the medical factors. Example: 5 mm or more is positive in An HIV-positive person Persons with recent contacts with a TB patient Persons with nodular or fibrotic changes on chest X-ray consistent with old healed TB Patients with organ transplants, and other immunosuppressed patients I am not HIV positive. I am currently tested. I am not in recent contacts with a TB patient. I am not working in nursing home. I do not have nodular or fibrotic changes on chest X-ray. I have current chest x-ray and its negative. Findings: Normal chest. I do not have organ transplant. BUT I have 8mm induration after 48 hours. How do you interpret this? Am I negative or positive in Skin TB Test? Any advice? I am so worried about it because this might be a reason for hindering me in entering the Nursing program. Please advice me. Thanks.
