用法筆記

Uncountable — do not say 'a cholesterol' or 'cholesterols'. Frequently paired with adjectives 'high' and 'low' to indicate risk level. 'Bad cholesterol' refers to LDL (low-density lipoprotein) and 'good cholesterol' refers to HDL (high-density lipoprotein); these are everyday rather than clinical terms.
