Frequently asked questions
The normal range for apoB varies depending on the ranges used by the lab processing your results, but generally, it’s <1 g/L for apolipoprotein B.
What is a normal apoB blood test result?
What happens if my apoB test result is high?
Having a high apoB level doesn’t cause any obvious symptoms. Most people with high apoB levels don’t find out they have it until they develop a serious health condition, such as a heart attack or stroke.
As you can have a high apoB level without knowing, you may wish to monitor your level or repeat your apolipoprotein test following lifestyle changes. Alternatively, your doctor may advise monitoring your cholesterol levels.
What can I do to lower my apoB level?
Making changes to your lifestyle such as taking regular exercise and following a heart-healthy diet, such as the Mediterranean diet, can help to lower your apoB level. And this can help decrease your risk of heart disease.
Controlling any underlying medical conditions that could contribute to a raised apoB level, such as diabetes and hypothyroidism, can also help to get your level into the normal range.
In some cases, you may be prescribed medication. Your GP will be able to offer advice and guidance if your apoB level is outside the normal range.
What does a low apoB test result mean?
A low apoB test result could be due to an underlying health condition such as an overactive thyroid (hyperthyroidism) or advanced liver disease. Malnutrition, severe illness, or medications (like thyroxine or statins) can also contribute to lower levels of apoB. Very rarely, genetic conditions, such as apolipoprotein B deficiency or Bassen-Kornzweig syndrome, may cause abnormally low levels of apoB.
