In some cases, such as hypertriglyceridemia, due to the increase of TRL and residual particles as well as sdLDL particles, the ApoB level is high and the cholesterol level is relatively low, therefore, the so-called “hyper-ApoB” may occur in which the LDL-C level is not high but the serum ApoB level is increased. Here, APOB is linked to hypertriglyceridemia.
