APO E

Description

"Apolipoprotein E" (ApoE) test evaluates genetic variants of the ApoE gene, which affect how your body processes fats and influence Alzheimer’s and cardiovascular risk. Doctors may order this test when there’s a family history of memory decline or heart disease. Certain ApoE variants, especially ApoE4, are linked to higher Alzheimer’s risk. Results inform prevention strategies, guide treatment changes, and support early planning. This test plays a key role in personalized risk assessment and long-term brain and heart health.

Test Group Description

Chronic Illness Group: This group encompasses a range of tests specifically tailored to assess markers associated with chronic health conditions, providing comprehensive insights into the management and monitoring of chronic illnesses.

Optimal Range

For All Individuals:

  • Conventional Unit: Not Available (ApoE protein level) | APOE4: Negative

  • SI Unit: Not Available (ApoE protein level) | Not Applicable

Normal Range

For All Individuals:

  • Conventional Unit: 2.00–5.00 mg/dL (ApoE protein level) | APOE4: Negative

  • SI Unit: 0.02–0.05 g/L (ApoE protein level) | Not Applicable

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • Alzheimer's Disease (Neurodegenerative disorder affecting memory and cognitive function)

  • Chronic Kidney Disease (Long-term kidney damage)

  • Chronic Liver Disease (Long-term liver damage)

  • Cerebrovascular Disease (Disorders affecting blood vessels in the brain)

  • Familial Hypercholesterolemia (Genetic disorder leading to high c...

Key Reasons For Testing

  • Cardiovascular Risk Assessment: Evaluates how ApoE variants influence heart disease and clogged artery risk.

  • Alzheimer’s Disease Risk: Identifies ApoE4 as a genetic marker for increased Alzheimer’s risk.

  • Lipid Metabolism Regulation: Assesses ApoE’s role in managing cholesterol and fat removal from the blood.

  • Atherosclerosis and Vascular Health: Examines ApoE’s impact on inflammation and vascular integrity.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
