title: [Tetrazolim nitroblue reduction test. Influence of the latex on the reliability of the results].
abstract: The finding of sudden variations in the results of the N.B.T. reduction test, using Baehner and Nathan's technique, depending on the latex used, led the authors to doubt the quality of this latex. A comparative study was carried out on adult controls with two different types of latex. With the new type of latex, the results were more reproducible and the sensitivity of the technique was increased. A study in rheumatoid arthritis confirmed these two findings and showed that the new latex was more reliable using the N.B.T. reduction test.
