ABP

Description

"Amyloid-Beta Peptide" test measures levels of amyloid-beta proteins in cerebrospinal fluid or blood to assess risk for Alzheimer’s disease. Abnormal levels may indicate amyloid plaque buildup in the brain, often linked to cognitive decline. Doctors order this test when symptoms like memory loss or confusion raise concern. Results help detect early changes associated with Alzheimer’s and guide further evaluation or treatment. Ongoing monitoring supports diagnosis, tracks progression, and helps personalize care for patients facing neurocognitive symptoms.

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 (> 50 years):

  • Conventional Unit: Not Available

  • SI Unit: Not Available

Normal Range

For All Individuals (> 50 years):

  • Conventional Unit: > 620.00 ng/L

  • SI Unit: Not Frequently Used

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

Abnormal results may indicate:


  • Alzheimer's disease (Neurodegenerative disorder characterized by cognitive decline and memory loss)

  • Frontotemporal dementia (Brain disorder leading to changes in behavior, personality, and language due to frontal and temporal lobe degeneration) 

  • Lewy body dementia (Progressive dementia with abnormal protein deposits known as Lewy bodies in the brain) 

  • Mild cogn...

Key Reasons For Testing

  • Diagnosis of Alzheimer’s Disease: Measures amyloid-beta levels to aid in diagnosing Alzheimer’s.

  • Prediction of Disease Progression: Evaluates how Alzheimer’s may advance based on amyloid-beta levels.

  • Assessment of Treatment Response: Tracks changes in amyloid-beta to evaluate therapy effectiveness.

  • Screening for Alzheimer’s Risk: Identifies individuals at higher risk, especially with a family history.

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.
