Bloodspot Fatty Acids Profile

Why use Bloodspot testing ?

  • Easy to implement in any practice
  • Does not require venipuncture
  • Cost-effective testing & therapy
  • Easy enough for patients to use at home
  • Simple and economical option for follow-up testing

Why use the Bloodspot Fatty Acids Profile*?

From a simple finger stick it measures key omega-3 and omega-6 fatty acids and calculates key indicators to establish your optimal balance. Trans fatty acids the "bad" oils in processed foods are also measured.

  • Improve patient compliance - Testing guides and supports your recommendations for higher doses of fatty acid supplements.
  • Inflammatory balance - Improper fatty acid intake affects the balance of anti- and pro-inflammatory eicosanoids, increasing health risks.
  • Increased free radical production - Consumption of polyunsaturated fatty acids (PUFAs) without increasing antioxidant intake will cause increased production of free radicals.

Test name(s)

0241 - Bloodspot Fatty Acid Profile*

Method

GC/MS

Fatty Acids measured:

Polyunsaturated Omega-3

  • ALA (Alpha-Linolenic Acid)
  • EPA (Eicosapentaenoic Acid)
  • DHA (Docosahexaenoic Acid)

Polyunsaturated Omega-6

  • LA (Linoleic Acid)
  • GLA (Gamma Linolenic Acid)
  • DGLA (Dihomogamma Linolenic Acid)
  • AA (Arachidonic Acid)

Trans

  • Total C:18 Trans

Indicators calculated:

  • AA : EPA ratio - A measure of "silent" inflammation
  • EPA + DHA % - An early CVD risk indicator
  • LA : GLA Ratio - Delta6 desaturase inhibition by decreased Zn or decreased Mg, increased insulin, or dietary excess of saturated or trans fatty acids
  • EPA : DGLA Ratio - Helps balance intake of Series-3 and Series-1 eicosanoid precursors
