Used For

Clinical Significance

1. Baseline and monitoring of individuals with known CVD (acute and chronic) to determine Rx and compliance.
2. Identify patients with known CVD risk with low omega-3 levels who may be candidates for supplementation/therapy.
3. Monitor patients on omega-3 supplementation/therapy to determine efficacy of treatment.
4. Potential role in risk reduction for non-CVD outcomes-aged related macular degeneration, RA, cancer, etc. (early data).
