A method for enhancing the chemiluminescent signal of an acridinium ester in a chemiluminescent reaction which comprises oxidizing the acridinium ester in the presence of an enhancer selected from the group consisting of: (a) a cationic surfactant; (b) a nonionic surfactant; and (c) a sulfated primary alcohol.

Method for enhancement of chemiluminescence

A method for determining thyroxine uptake of a sample serum comprising: (a) incubating the sample serum with solid phase thyroxine and labeled anti-TBG antibody; (b) separating the solid phase from the unbound labeled antibody; (c) measuring the amount of label associated with the solid phase; and (d) calculating the thyroxide uptake ratio of the sample serum by relating the measurement of step (c) to a measurement of a reference serum.
