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:
“Passions spin the plot:
We are betrayed by what is false within.”
—George Meredith (1828–1909)
“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)
“If it is the result of a pure love, there can be nothing sensual in marriage. Chastity is something positive, not negative. It is the virtue of the married especially. All lusts or base pleasures must give place to loftier delights. They who meet as superior beings cannot perform the deeds of inferior ones.”
—Henry David Thoreau (1817–1862)
