CHESTERFIELD, VA (WWBT) -
Tests for tuberculosis are common- especially if you are entering a new school or work.
But the tests are changing. We explain in this week's Neighborhood Healthwatch.
In Waterford Dr. Sheila Clasbey explains how things are different.
There is a shortage of PPD for injection into the skin on the arm, the new tool is a laboratory blood test that the doctor must order.
You don't need to come back a second time- instead you go to a lab just once. But it takes a few days for the results to come back.
This is a change in a fairly common screening procedure.
