Table 1. Diagnostic Criteria for Dyslipidemia (Blood Collected from Patients in Fasting State)*.
LDL-C | ≥ 140 mg/dL | Hyper-LDL cholesterolemia |
120–139 mg/d | Borderline hyper-LDL cholesterolemia** | |
HDL-C | < 40 mg/dL | Hypo-HDL cholesterolemia |
TG | ≥ 150 mg/dL | Hypertriglyceridemia |
Non-HDL cholesterol | ≥ 170 mg/dL | Hyper-non-HDL cholesterolemia |
150–169 mg/dL | Borderline hyper-non-HDL cholesterolemia** |
“Fasting state” is defined as fasting for at least 10 h. However, consumption of liquids with no calories, such as water and tea without milk or sugar, is allowed.
If screening shows borderline hyper-LDL cholesterolemia and borderline hyper-non-HDL cholesterolemia, investigate whether a high-risk condition is present and consider the need for treatment.
- LDL-C is derived using the Friedewald formula (TC.HDL-C.TG/5) or through a direct method.
- Non-HDL-C (TC.HDL-C) or a direct method is used if the TG level is 400 mg/dL and greater or if postprandial blood is collected. However, if hypertriglyceridemia is absent during screening, the risk shall be assessed with the consideration that the difference from LDL-C can possibly turn out to be smaller than + 30 mg/dL.
