APOB and hypertriglyceridemia: According to the apoB algorithm, type IIa (HLP2a) and IIb (HLP2b) are identified by apoB ≥ 120 mg/dL together with variable plasma TG levels, while type I (HLP1), III (HLP3), IV (HLP4), and V (HLP5) are identified by apoB < 120 mg/dL with moderately to severe hypertriglyceridemia (HTG) [5].
