How accurate is a tb skin test for detecting tuberculosis?
-
The tb skin test is one of the most commonly used screening tools for detecting tuberculosis infection, and while it is generally reliable, its accuracy can vary depending on a person’s immune status, history of TB exposure, and whether they have received the BCG vaccine. The test works by measuring the body's immune response to injected TB proteins, but false positives may occur in individuals who have had the BCG vaccine, while false negatives can happen in people with weakened immune systems or recent TB exposure. Despite these limitations, the TB skin test remains a valuable and accessible screening method, especially when paired with risk assessment and additional diagnostic tools like chest X-rays or blood tests.
