Results

Name Units Reference Range Conversion Factor
(All reported fatty acids) % weight
  • None
Docasahexaenoic Acid C22:6n-3 % weight
  • None
DHA (Docosahexaenoic Acid) scores of >4.50 are associated with low risk of CHD.
Total Omega-3 Fatty Acids % weight
  • None
Total Omega-3 scores of > 7.20 are associated with low risk of CHD
Total Omega-6 Fatty Acids % weight
  • None
Interpretive guidelines for Omega-6 scores have not been established.
EPA + DHA (20:5n3+22:6n3) % weight
  • None
EPA (Eicosapentaenoic Acid) plus DHA scores of > 4.60 are associated with low risk of fatal heart disease.
OM3/OM6 Ratio
An Omega-3/Omega-6 score of 1:3 is consistent with anti-inflammation.
AA/EPA Ratio
Interpretive guidelines for the ratio of AA (Arachidonic Acid) to EPA have not been established.
