Randox Biosciences Biochip Blood Test Detects Elevated Risk for Alzheimer’s Disease

Researchers today unveiled results from a new blood test to help identify which patients are at an elevated risk of Alzheimer’s disease. The findings, presented at the 68th AACC Annual Scientific Meeting & Clinical Lab Expo in Philadelphia, showed that the biochip test, which allows multiple tests to be run on one blood sample, was as accurate as existing molecular tests that analyze DNA.

“This is the first time that we have used this biochip technology to test for an increased risk of Alzheimer’s disease,” said Emma C. Harte, PhD, a research scientist at Randox Laboratories. “This type of testing is important in our quest to understand and diagnose Alzheimer’s and empower patients to understand risks, consider medication, and even make early lifestyle changes.”

This test detects the presence of a protein in the blood produced by a specific variation of the apolipoprotein gene (ApoE4), which is associated with increased risk of developing Alzheimer’s disease. The apolipoprotein gene is inherited from each parent and when a patient inherits the ApoE4 variant from one parent they have a three times greater risk of developing Alzheimer’s disease, whereas a patient who inherits ApoE4 from both parents is eight-to-12 times more likely to develop the disease.

To verify the accuracy of the biochip test, 384 samples were analyzed and results compared to those from a standard molecular diagnostic test. Researchers from Randox Laboratories collaborated with research colleagues at the Medical University of Vienna and found that results from the two tests were in 100% agreement. As biochip tests allow clinicians and researchers to quickly run multiple tests on one sample of blood, this new test is also faster and more affordable than the standard DNA test, producing results in only three hours. This enables doctors to predict the risk of an individual developing Alzheimer’s disease.

“Pairing this test with medical and family history for risk of Alzheimer’s disease has the real potential to advance personalized medicine,” said Harte. “This fast, accurate testing will allow doctors and patients to make more informed choices earlier to potentially slow the possible progress of Alzheimer’s.”

We were also honoured to receive a NACB / AACC Distinguished Abstract Award for our exciting product launch. Out of 1024 posters presented at the diagnostics conference, which is the largest of its kind globally, the poster for our new APOE4 test, presented by our Dr. Emma Harte, was one of only 29 to receive this prestigious award.

In combination with information on medical and family history, medication, and lifestyle, an individual’s ApoE4 status, as obtained from the Randox Biochip test, can go a long way in advising personalised medicine for the patient.

“This type of testing is important in our quest to understand and diagnose Alzheimer’s and empower patients to understand risks, consider medication, and even make early lifestyle changes,” said Emma, our R&D Scientist.
