New Alzheimer’s Test Can Predict Disease 15 Years before of Symptoms

ALZpath's pTau217 blood test has been found to be as accurate as standard lumbar punctures and superior to brain atrophy assessments in identifying signs of Alzheimer's disease[4]. The test showed high diagnostic accuracy, with an area under the curve (AUC) of 0.92-0.96 for amyloid and 0.93-0.96 for tau, making it comparable to or better than other diagnostic methods[1][3]. According to a study published in the Journal of the American Medical Association, the test demonstrated a high diagnostic accuracy of approximately 80% in identifying elevated biomarkers, which is comparable to more invasive and expensive methods[3]. The test has also been reported to be capable of detecting symptoms of Alzheimer's disease up to 15 years in advance, making it a breakthrough in early detection[2]. The high accuracy and early detection capabilities of the ALZpath pTau217 test position it as a promising tool for the precise and timely diagnosis of Alzheimer's disease.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
