How we got here


Laying the Bedrock

Responding to urgent national defense needs, Sandstone’s founders begin work on a new point-of-care clinical diagnostic technology at Sandia National Labs that will enable first responders to rapidly screen large populations in emergency scenarios. The “SpinDx” system uses centrifugal forces generated in spinning disposable plastic disks to simultaneously quantify protein biomarkers and white blood cells from small volumes of whole blood. 


Improvements and Striations

In several head-to-head comparison tests at Sandia, SpinDx is shown to outperform gold standard laboratory methods in terms of speed, sample volume, and sensitivity. The team is awarded federal research grants to expand the SpinDx assay portfolio and further develop the handheld, battery powered device. SpinDx evolves from a science experiment into a versatile, powerful, cutting-edge diagnostic platform.


Sandstone Formation

Sandstone Diagnostics is founded in July 2012 to develop comprehensive diagnostic products that bring clinical tests out of the laboratory and into the hands of the people who need them. The company secures a license to Sandia’s technology and continues to build its own technology portfolio to build, manufacture, and distribute products that meet both the performance specifications for clinical testing and reliability requirements for consumer use. Sandstone’s team gels into a scrappy start-up ready to change the way people monitor and manage their health.


Crystallization of Trak Fertility

Sandstone’s lead product, Trak, is born from the company’s unique capability to rapidly quantify cells in biological samples. Trak is a new approach to fertility improvement that empowers couples to monitor key sperm parameters at home as they take steps to boost their fertility and improve their chances of conception. Sandstone is also awarded a grant from the U.S. National Institutes of Health to further develop its core diagnostic platform for monitoring the health status of newborn babies in neonatal intensive care units.  


Growth and Stratification

Having proven that Trak meets the accuracy of a laboratory semen analysis, Sandstone is currently focused on bringing the product to market. The company is developing a mobile app and online educational resources to complement the hardware product and give couples a comprehensive approach to fertility improvement. Sandstone is also collaborating with external development partners to expand its core suite of clinical assays for fertility applications as well as additional medical conditions. Sandstone is off to the races and positioned to change the face of clinical testing and health management.
