What is true regarding blood tuberculin tests?

Question

Quizplus · Accepted Answer

When a patient has had the BCG vaccine or has an issue returning for the skin test reading, the blood test is preferred. The blood test replaces the skin test. A healthcare professional/student only needs one blood test initially, unlike the two-step skin test. The error rate with a blood test is much less than the palpated/measured reading of the skin test. If the TB blood test is:
F1F1F1S1F1F1F10 Positive: then the person has been infected with TB. The provider will order additional tests to determine if the person has latent TB infection or TB disease. (See Chapter 11 Respiratory System for more information on these two diseases.)
