There remains the need for an accurate, automated, direct immunoassay for testosterone. Studies comparing a prototype ARCHITECT® 2nd Generation Testosterone Immunoassay* to LC-MS/MS with male and female specimens are described. Versus LC-MS/MS Gallacher et al: 2nd Gen Testosterone = 1.02 LC/MS/MS - 0.2; R2 = 0.99; 75 male,120 female. Female only R2 = 0.90 Versus LC-MS/MS UK NEQAS ALTM: 2nd Gen Testosterone = 0.989 LC/MS/MS – 0.16; R2 = 0.99; 75 male, 120 female specimens. For female specimens up to 2.5nM R2 = 0.95 The prototype ARCHITECT® 2nd Generation Testosterone Assay is capable of measuring both male and female samples accurately and precisely. * The ARCHITECT® 2nd Generation Testosterone Assay is currently in development.
