The standard lipid panel measures the main circulating fats — LDL-C is the classic risk marker, but triglycerides and HDL contextualise it, and the TG/HDL ratio is a strong proxy for insulin resistance. Reading the four numbers together tells you far more than LDL alone.

The biomarker

  • Name: Lipid Panel — LDL, HDL, Triglycerides
  • Units: mg/dL
  • Standard reference range: LDL < 130; HDL > 40 (men) / > 50 (women); TG < 150
  • Optimal range: LDL < 100; HDL > 60; TG < 100; TG/HDL < 1.5

How to read your result

ResultInterpretation
LDL > 130Elevated — pair with ApoB
HDL < 40Low — consider cardio + monounsaturated fats
TG > 150High — review carbohydrate and alcohol
TG/HDL > 2Insulin-resistance signal

What moves the needle

  • Diet. Reduce refined carbs; add fiber and omega-3.
  • Movement. Weekly aerobic plus strength work.
  • Further testing. Add ApoB and Lp(a) for the full atherogenic picture.
  • Retest. 3 months after a change to see the effect.

Why this test is worth asking for

  • It is on nearly every basic panel, so the four numbers are usually already available — the value is in reading them together rather than fixating on LDL.
  • The TG/HDL ratio doubles as an insulin-resistance signal, linking the lipid panel to metabolic health.
  • It sets the baseline for deciding whether to add sharper markers like ApoB and Lp(a).
