President, Owner

Sharmin Sriram is Founder and President of Spectrum MDX, a Toronto-based, leading supplier and distributor of rapid diagnostic screening devices.

After working as a POCT product specialist supporting Medical Directors and toxicology experts for over 25 years, Sharmin transformed her passion for personalizing healthcare services into her next successful business venture and formed Spectrum MDX in 2008. She has been at the forefront of rapid diagnostic technology for more than 25 years and has a proven track record of introducing innovative products and solutions that accelerate POCT clinical diagnosis. In 1999, Sharmin recognized the need for a more sensitive  and specific chemistry for rapid EDDP (Methadone metabolite) detection and was first to launch a rapid POCT device for this metabolite into the Canadian marketplace.

Sharmin has positioned her performance as a leader and aligns her business intelligence with North-American products that exceed her expectations of quality. Her entrepreneurial spirit has enabled her to build long-lasting relationships with manufacturers and industry peers that broaden her company’s product portfolio.
