If a Tuberculosis test (PPD) is given to you on your first visit, you are required to have your test read no sooner than 48 but no more than 72 hours. This test is to be done by a USCIS Licensed M.D. only.

If your Tuberculosis test results in redness and irritation on your forearm greater than 5mm, it is considered "positive" and you need to submit a chest x-ray. Be aware of the extra time involved to get your I-693 requirements accomplished. You can either get the x-ray done at the County Health Department or have your primary care physician order the x-ray. If you have no medical insurance, we can refer you to an x-ray clinic where you can get a 50% discount that we have negotiated for immigrants.

If you received a Tuberculosis vaccination (BCG) when you were a child in your native country (it can be identified as 1 or 2 scars on your right upper arm), you may react "positive" to the PPD. Just remember that if a reaction occurs at the test site, the USCIS requires that you have a chest x-ray done.

If you previously had a positive Tuberculosis test (PPD) and you have taken medications for 6 months, you are required to bring to your appointment a certificate that states from either your physician or Health Department official that you have successfully completed your medication program. If you have completed these requirements, the PPD will not be repeated.

If you had in the past a "positive" Tuberculosis test (PPD) and you have not taken any medications and if your chest x-ray was negative, you are required to bring your x-ray report to this appointment. If the report is older than one year, you will need to get a new chest x-ray done.
