About this service

APOE genotyping identifies specific alleles (ε2, ε3, ε4) to evaluate genetic risks for late-onset Alzheimer's and lipid disorders. It helps clinicians understand fat metabolism and cognitive health predispositions.

Clinical Significance

Assessing the risk for late-onset Alzheimer's disease.
Diagnosing hereditary Type III Hyperlipoproteinemia.
Providing essential data for personalized preventive care plans.

Who Should Consider Testing

Individuals with a family history of dementia or Alzheimer's.
Patients with persistent high cholesterol and triglycerides resistant to treatment.
Proactive individuals interested in genetic health screening.

Understanding the Genotypes

ε2 Allele: Associated with lower Alzheimer's risk but may impact lipid balance.
ε3 Allele: The most common allele, considered neutral in risk assessment.
ε4 Allele: Associated with an increased genetic predisposition to late-onset Alzheimer's.

What is included?

✓Blood sample collection
✓Genotype analysis (ε2, ε3, ε4)
✓Detailed medical report

Conditions and notices

Fasting is not required
No special preparations are required before the test

Frequently Asked Questions

Short answers to the FAQs published with this service.

What is the primary purpose of the APOE test?

The test identifies genetic variations that affect lipid metabolism and increase the risk for late-onset Alzheimer's disease.

Does having the ε4 allele mean I will definitely develop Alzheimer's?

No, having the allele only indicates an increased genetic risk; it is not a diagnosis, as lifestyle and environment also play roles.

Is fasting required for this genetic test?

No, fasting is not required for APOE genotyping. You can take the test at any time.

How is the sample collected?

The sample is collected through a standard blood draw from a vein in your arm.

How long does it take to get the results?

As this is a specialized genetic test, results typically take several business days to be processed and verified.

Can I perform this test at home?

Yes, home sample collection is available for this service through the Lahalak Medical Platform.
