A Field Ready Blood Test For The Precise Measurement Of Oxidative Stress

Oxidative Stress occurs when the body’s antioxidant defences are overwhelmed by an excess of toxic oxidants. Oxidative stress is implicated in over 70 health conditions, with levels often reflective of a person’s health condition and physical performance capability.

The OxiDx Test

Backed by over 15 peer-reviewed publications, OxiDx uses patented technology to detect subtle changes in protein structure. These changes can be detected via a simple fingerprick blood sample or small blood draw. The OxiDx test for systemic oxidative stress acts as an early warning system for overtraining in human and equine (horse) athletes and can be used as a routine monitoring tool for clinical trials and numerous inflammatory conditions.

Equine Athletes

85% of Thoroughbreds suffer at least one injury during their 2 or 3-year-old racing seasons

Competitive advantage from improved race-preparedness
Injury management and improved welfare
Inform veterinary investigations

Human Athletes

Up to 55% of all sports injuries are muscle injuries, with an annual average cost of $8M USD for professional teams

Competitive advantage from improved athletic preparedness
Injury management and rehabilitation
Individualise athlete training loads

Clinical Monitoring

Oxidative stress plays a critical role in disease development and progression

Track therapeutic response and efficacy
Accurate, scalable and cost-effective
Enables decentralised and remote testing

The OxiDx Advantage

Streamlined laboratory analysis permits ≤12 hour results turnaround

Highly sensitive, patented technology

Fingerstick or small volume permits sampling by anyone, anytime, anywhere

No cold-chain logistics or special mailing requirements

Cost-effective for routine sampling and large cohort collection

Simple results feedback for rapid decision making
