Creative Biolabs offers custom assay development services that bridge the path from discovery to product. Our scientific expertise provides highly custom solutions for unique in vitro diagnostics (IVD) assays to meet our clients' basic, applied and clinical research demands. It is applied to all assay development at Creative Biolabs, and it is the key to accelerating your innovation in IVD research.

Assay Development

The first step in developing a diagnostic assay is demonstrating the feasibility or the ability to detect the analyte under optimized conditions. Next, the process of evaluation usually consists of determining analytical metrics, including analytical sensitivity, analytical selectivity, limit of detection (LoD), trueness and precision. These analytical statistics provide an abundance of information about the assay including the quantitative change in response for varying analyte amounts, the reportable range and linear response of the assay, the smallest analyte amount, how interferents affect the response, and the trueness and precision of the assay.
