<p>I don't know anything about university policy, but in general, I think a negative chest x-ray is considered the same as a negative skin test. At least at one of the hospitals I've worked/volunteered in (not in Baltimore), they would accept proof of a negative skin test or negative chest x-ray for their health clearance process.</p>
<p>That said, ask Health and Wellness if you want to know about Hopkins' policy</p>
