Test Methodology

Spectrophotometric; LDL Cholesterol calculated by Friedwald formula

CPT Code


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)


Classification CHOL HDL LDL TRIG
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.

Critical Results


Test Limitations

Refer to individual test entries.

12 hour fasting specimen required.

LDL cholesterol calculation is invalid at triglyceride levels >400 mg/dL; in such cases, LDL cholesterol by direct measurement is recommended.
