Apolipoprotein B (ApoB) and low-density lipoprotein (LDL) are both important factors in cholesterol metabolism, but they are not the same.¹

ApoB is a protein that is found in several types of lipoproteins, including LDL, very-low-density lipoprotein (VLDL), and intermediate-density lipoprotein (IDL).² It helps to transport cholesterol and other fats throughout the body.³

LDL is a type of lipoprotein that carries cholesterol from the liver to the body's cells.⁴ It is often called "bad" cholesterol because high levels of LDL can increase the risk of heart disease.⁵

Both ApoB and LDL levels can be measured with a blood test. The normal ranges for ApoB and LDL can vary depending on age, sex, and other factors.⁶ However, in general, lower levels of both ApoB and LDL are associated with a lower risk of heart disease.

Here are some of the key differences between ApoB and LDL:

• ApoB is a protein, while LDL is a type of lipoprotein.⁷
• ApoB is found in several types of lipoproteins, while LDL is only one type of lipoprotein.
• ApoB is a component of LDL, but it is not the same as LDL.⁸
• Both ApoB and LDL can be measured with a blood test.⁹
• Lower levels of both ApoB and LDL are associated with a lower risk of heart disease.

Here are the general guidelines for interpreting ApoB and LDL levels:

• ApoB:
  • < 90 mg/dL: Low risk of heart disease
  • 90-129 mg/dL: Moderate risk of heart disease
  • > 130 mg/dL: High risk of heart disease¹⁰
• LDL:
  • < 100 mg/dL: Optimal
  • 100-129 mg/dL: Near optimal¹¹
  • 130-159 mg/dL: Borderline high¹²
  • 160 mg/dL or higher: High

It is important to note that these are just general guidelines, and your doctor should interpret your results in the context of your individual risk factors.
