Test Methodology

Spectrophotometric; LDL Cholesterol calculated by Friedwald formula

CPT Code

80061

Test Includes

Lipid Panel (CPT 80061) includes Cholesterol-total, HDL Cholesterol (direct measurement), Triglycerides and a calculated value for LDL Cholesterol.  Each of these may be ordered individually except for the calculated LDL. A test or panel may be ordered only when all components are medically necessary to diagnose or treat an individual patient.  If all components are not medically necessary, a less inclusive panel and/or an individual test as appropriate to treat the individual patient should be ordered.

Reference Range

NCEP Adult Treatment Panel III Classification (mg/dL)

Desirable/Optimal <200 >59 <100 <150
Near/Above Optimal -- -- 100-129 --
Borderline High 200-239 -- 130-159 150-199
High Risk >239 <40 160-189 200-499
Very High -- -- >189 >499

 

 

  • LDL-cholesterol calculated by the Friedewald formula may also include non-HDL cholesterol from Lp(a), another emerging lipid risk factor in coronary heart disease.
  • The calculation of the LDL-cholesterol concentration according to Friedewald’s formula can give rise to falsely low LDL-cholesterol values in the presence of small amounts of chylomicrons or abnormal lipoproteins.

Test Limitations

Refer to individual test entries.
