Frequency of false‐negative reactions to the fragrance mix

Contact Dermatitis, 1993
To estimate the frequency of false‐negative‐ reactions to the fragrance mix, the 8 constituents of the mix in concentrations of 5% (2% for cinnamic aldehyde) were added to the European standard series for routine testing. Patients with positive reactions to individual ingredients in the absence of a reaction to the mix were retested with serial ...

False negative and prozone reactions in tests for antibodies to Epstein‐Barr virus‐associated nuclear antigen

International Journal of Cancer, 1974
AbstractTitration of anti‐complementary human sera may yield false negative or prozone reactions in anti‐complement immunofluorescence (ACIF) tests for antibodies to Epstein‐Barr virus‐associated nuclear antigen (EBNA) when the human complement (C') is added to the serum dilutions prior to charging of the target cell smears (two‐stage ACIF test).

False negative hyperglucosuria test-strip reactions in laboratory mice

Laboratory Animals, 1982
Inhibition of a variety of commercial test strips for hyperglucosuria was experienced in laboratory mice. All mouse strains tested were found to have sufficiently high levels of ascorbic acid to cause inhibition, and male levels were higher than those of females. A regime to obtain optimum detection of positive results is discussed.

False-negative oxidase reaction as a result of medium acidification

Antonie van Leeuwenhoek, 1980
Acidification of the culture medium may lead to a false-negative result of the oxidase reaction. Hence, if the medium contained a carbon source or another component that is convertible to acid, a negative oxidase reaction should be considered inconclusive.

Fragrance patch tests prepared in advance may give false‐negative reactions

Contact Dermatitis, 2014
SummaryBackgroundSeveral of the ingredients in fragrance mix I (FM I) have been shown to evaporate from petrolatum preparations applied in test chambers to an extent that can be suspected to affect the patch test result.ObjectivesTo compare the reactivity towards FM I and fragrance mix II (FM II) when they are applied in test chambers in advance and ...
