Dr. Sampath Srikanth, PhD, MBA, CEO. Over 10 years’ relevant experience in business development, product management and general management at IDEXX Laboratories, Inc. (IDXX).

Incorporated in 2008, DermDx has had its first prototype DDx instrument in clinical trials since 2009. The company was founded in Fresno California by Sampath Srikanth and Robert S. Hulsy, experienced medical device entrepreneurs and managers. DDx is poised to become the industry leader for ease of use, accuracy, range of lesions diagnosed and cost. 

Our mission is to revolutionize in-clinic diagnosis of skin cancer, 
greatly increasing speed and accuracy, improving the patient experience, and reducing cost.


​Our solution is a totally new approach for skin cancer diagnosis. Rather than depending on what the eye can see, The DDx senses specific biological and biochemical factors within suspect tissue that are indicative of disease. The DermDx solution offers greatly improved diagnostic accuracy. The DDx will save lives. Research shows that with this capability skin cancer deaths will be cut by more than half while the overall financial cost to the health care system will be dramatically reduced.

Using recently developed technology, skin cancer can be non-invasively diagnosed at an accuracy level approaching that of anatomical pathology (the gold standard of skin cancer diagnosis).

Using multi-modal spectroscopy, the company’s first product, the DDX, uses the “biological signature” of a cancer cell for diagnosing cancerous lesions. Traditionally, skin cancer is diagnosed by various approaches using the human eye.

In a small clinical trial run at the MD Anderson Cancer Center in Dallas to test the efficacy of our method, the DDx demonstrated very high sensitivities and specificities. The DDx diagnosed melanomas with sensitivity/specificity of 100/94.

The DDx will be useful in skin cancer screening settings such as the national screening programs in Germany and Canada. It can also be used for large multi-phasic exams such as for the US Army in induction physicals.

The DDx has a significant ability to cut medical system costs by reducing negative biopsies in the dermatology office as well. Lesions even smaller 2 mm diameter can be diagnosed allowing earlier identification of dangerous cancers.

With the DDX now in the prototype stage, DermDx, Inc. is seeking Series A financing to obtain regulatory approval and to staff up for launch in Europe
