About Us

SpectraDigital Corporation (SDC) is a technology company that specializes in the development of simple, easy-to-use, medical diagnostic tests for use in low-resource settings. SDC is also actively engaged in developing agricultural applications.

The SpectraDigital platform can be adapted for use in a variety of applications. HIV SpectraPoint, is our first application that assesses the efficacy of AIDS anti-virals using a simple blood test. This method can provide information similar to the genotype/phenotype test at a much lower cost making access to diagnostics more accessible.

Other uses for SDC’s platform include developing lead chemistries, drug assessment, evaluating the efficacy of drugs, environmental monitoring, and other settings involving the measurement of cellular reactions and cellular response to metabolic agents.

Advantages of SDC’s technology platform include:
