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:
“It is better to be true to what you believe, though that be wrong, than to be false to what you believe, even if that belief is correct.”
—Anna Howard Shaw (18471919)
“The idealists 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 (18641929)
“The innocence of those who grind the faces of the poor, but refrain from pinching the bottoms of their neighbours wives! The innocence of Ford, the innocence of Rockefeller! The nineteenth century was the Age of Innocencethat sort of innocence. With the result that were now almost ready to say that a man is seldom more innocently employed than when making love.”
—Aldous Huxley (18941963)
