Guidance for Informed Choice on Beryllium Testing

This is not a test that your doctor would routinely perform. Only a handful of laboratories in the U.S. can perform it. Because 1 out of 4 people who have one abnormal test do not have an abnormal result on a second test, two abnormal tests are required to indicate that a person is sensitized to beryllium. However, the Department of
