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:
“If I be false, or swerve a hair from truth,
When time is old and hath forgot itself,
When waterdrops have worn the stones of Troy,
And blind oblivion swallowed cities up,
And mighty states characterless are grated
To dusty nothing, yet let memory
From false to false among false maids in love
Upbraid my falsehood.”
—William Shakespeare (1564–1616)
“There is no reason why parents who work hard at a job to support a family, who nurture children during the hours at home, and who have searched for and selected the best [daycare] arrangement possible for their children need to feel anxious and guilty. It almost seems as if our culture wants parents to experience these negative feelings.”
—Gwen Morgan (20th century)
“... as a result of generations of betrayal, it’s nearly impossible for Southern Negroes to trust a Southern white. No matter what he does or what he suffers, a white liberal is never established beyond suspicion in the hearts of the minority.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 10 (1962)
