摘要
Rapid identification of Candida albicans is performed mainly by the germ-tube test. However, recent reports have suggested that up to 5% of C. albicans species can give false negative results. We describe the use of 4-Methylumbelliferyl N-acetyl-beta-D-galactosaminide (4-MAG) conjugate as an alternative to the germ-tube test. Our results indicate that, in comparison to the germ-tube test, the 4-MAG test has a sensitivity of 100% and a specificity of 92%. Candida tropicalis can give false-positive results, and that a further screening test is required to identify this species. Problems reading end-points were not encountered.
