The ARK™ Topiramate Assay is a homogeneous enzyme immunoassay intended for the quantitative determination of topiramate in human serum or plasma on automated clinical chemistry analyzers. The results obtained are used in the diagnosis and treatment of topiramate overdose and in monitoring levels of topiramate to help ensure appropriate therapy.

The ARK™ Zonisamide Assay is a homogeneous enzyme immunoassay intended for the quantitative determination of zonisamide in human serum or plasma on automated clinical chemistry analyzers. Zonisamide concentrations can be used as an aid in management of patients treated with zonisamide. The ARK™ Zonisamide Assay consists of reagents RI anti-zonisamide polyclonal antibody with substrate and R2 zonisamide epitope labeled with bacterial G6PDH enzyme.

The ARK™ Pregabalin Urine Assay is a homogeneous enzyme immunoassay intended for the quantitative and/or semi-quantitative analysis of pregabalin in human urine.

The ARK™ Pregabalin II Assay is an immunoassay intended for the qualitative and/or semiquantitative determination of pregabalin in human urine at a cutoff concentration of500 ng/mL.
