False Negative Result
Those who are immunologically compromised, especially those with HIV and low CD4 T cell counts, frequently show negative results from the PPD test. Steroid use, malnutrition and sarcoidosis can also lead to false-negative results, because the immune system needs to be functional to mount a response to the protein derivative injected under the skin.

Famous quotes containing the words false, negative and/or result:
“Love is too prone to trust. Would I could think
My charges false and all too rashly made.”
—Ovid (Publius Ovidius Naso)
“The idealist’s programme of political or economic reform may be impracticable, absurd, demonstrably ridiculous; but it can never be successfully opposed merely by pointing out that this is the case. A negative opposition cannot be wholly effectual: there must be a competing idealism; something must be offered that is not only less objectionable but more desirable.”
—Charles Horton Cooley (1864–1929)
“To the indefinite, uncertain mind of the American radical the most contradictory ideas and methods are possible. The result is a sad chaos in the radical movement, a sort of intellectual hash, which has neither taste nor character.”
—Emma Goldman (1869–1940)
