Reference Values:

Age	Decision Limit	Comment
<10 y	<1.10 mmol/L	If fasting: Desired: < 0.80 mmol/L Borderline: 0.80 - <1.10 mmol/L Increased risk: >= 1.10 mmol/L If nonfasting, triglycerides are, on average, elevated 20% above fasting levels, however individual patients may vary.
10-19 y	<1.50 mmol/L	If fasting: Desired: < 1.00 mmol/L Borderline: 1.00 - <1.50 mmol/L Increased risk: >= 1.50 mmol/L If nonfasting, triglycerides are, on average, elevated 20% above fasting levels, however individual patients may vary.
>/= 20 y	<1.70 mmol/L	If nonfasting, triglycerides <2.00 mmol/L acceptable

If triglycerides >9.04 mmol/L, LDL-C (NIH equation) will not be calculated.

Method of Analysis: Roche Cobas or Ortho Vitros: enzymatic, colorimetric
