Recommended Cut Points for Lipid and Lipoprotein Levels in Young Adults

CategoryLow, mg/dLBorderline-Low, mg/dLAcceptable, mg/dLBorderline-High, mg/dLHigh, mg/dL
TC<190190–224≥225
LDL cholesterol<120120–159≥160

  • Values provided are from the Lipid Research Clinics Prevalence Study. The cut points for TC, LDL cholesterol, and non-HDL cholesterol represent the 95th percentile for 20- to 24-year-old subjects and are not identical with the cut points used in the most recent NHLBI adult guidelines, Adult Treatment Panel III (“Third Report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults”), which are derived from combined data on adults of all ages. The age-specific cut points given here are provided for pediatric care providers to use in managing this young adult age group. For TC, LDL cholesterol, and non-HDL cholesterol, borderline-high values are between the 75th and 94th percentiles, whereas acceptable value are at the <75th percentile. The high triglyceride cut point represents approximately the 90th percentile; borderline-high values are between the 75th and 89th percentiles, and acceptable values are at the <75th percentile. The low HDL cholesterol cut point represents approximately the 25th percentile; borderline-low values are between the 26th and 50th percentiles, and acceptable values are at the >50th percentile.
