鈥淭his is the first time that we have used this biochip technology to test for an increased risk of Alzheimer鈥檚 disease,鈥� said Emma C. Harte, PhD, a research scientist at Randox Laboratories. 鈥淭his type of testing is important in our quest to understand and diagnose Alzheimer鈥檚 and empower patients to understand risks, consider medication, and even make early lifestyle changes.鈥�
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鈥檚 disease.
鈥淧airing this test with medical and family history for risk of Alzheimer鈥檚 disease has the real potential to advance personalized medicine,鈥� said Harte. 鈥淭his fast, accurate testing will allow doctors and patients to make more informed choices earlier to potentially slow the possible progress of Alzheimer鈥檚.鈥�
In addition to this study, researchers will present the latest in Alzheimer's disease at the AACC Annual Scientific Meeting & Clinical Lab Expo, including:
鈥� New research explores using the level of angiotensin-converting enzyme (ACE) in the brain and spinal cord as a biomarker for neurodegenerative diseases, including Parkinson鈥檚 disease and AD. 鈥溾�� (A-118)
鈥� Researchers have shown that a specific protein in blood plasma could serve as a biomarker for early detection of AD. 鈥溾�� (A-135)
鈥� A new meta-analysis of studies over 12 year suggests that a possible relationship between thyroid function and an increased risk of dementia. 鈥溾�� (A-180)

About the 68th AACC Annual Scientific Meeting & Clinical Lab ExpoThe AACC Annual Scientific Meeting offers 5 days packed with opportunities to learn about exciting science from July 31鈥揂ugust 4. Plenary sessions feature the latest research on the use of and testing for cannabis, combating premature death due to preventable causes such as tobacco and alcohol, the development of an 鈥渋ntelligent鈥� surgical knife, programmable bio-nano-chips, and the epigenetic causes of disease.
At the AACC Clinical Lab Expo, more than 750 exhibitors will fill the show floor of Philadelphia鈥檚 Pennsylvania Convention Center, with displays of the latest diagnostic technology, including but not limited to mobile health, molecular diagnostics, mass spectrometry, point-of-care, and automation.
