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:
“Hospitality still survives among foreigners, although it is buried under false pride among the poorest Americans.”
—Jane Addams (1860–1935)
“Coming out, all the way out, is offered more and more as the political solution to our oppression. The argument goes that, if people could see just how many of us there are, some in very important places, the negative stereotype would vanish overnight. ...It is far more realistic to suppose that, if the tenth of the population that is gay became visible tomorrow, the panic of the majority of people would inspire repressive legislation of a sort that would shock even the pessimists among us.”
—Jane Rule (b. 1931)
“Mothers are likely to have more bad days on the job than most other professionals, considering the hours: round-the-clock, seven days a week, fifty-two weeks a year. . . . You go to work when you’re sick, maybe even clinically depressed, because motherhood is perhaps the only unpaid position where failure to show up can result in arrest.”
—Mary Kay Blakely (20th century)
