Test Comments:
Methodology:
Chromatography Mass Spectrometry
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).
Documentation:
Effective August 17th 2015, Omega-3 and Omega-6 Fatty Acid test (NTC 91001) will be performed with an improved methodology requiring new reference ranges and cut-points. After August 17th, please do not compare prior results to the new results, reference ranges, and cut-points. If you would like to re-baseline your patients previously tested with the older version of NTC 91001, please call the Client Services of the testing laboratory at 1800-642-4657 Ext 3222.
