A modern blood test for the investigation of Alzheimer’s disease

Memory loss and changes in thinking should not be ignored.

The pTau181 test now offers the possibility to accurately investigate the biological processes associated with Alzheimer’s disease through a simple blood test.

At LIFECHECK medical laboratories, we combine scientific evidence with cutting-edge technology, providing reliable laboratory support for both the individual being tested and the treating physician.

What is pTau181 and why it matters

pTau181 is a specific form of the Tau protein that is directly associated with the characteristic pathological changes observed in the brain in Alzheimer’s disease.

These changes begin many years before the first clinical symptoms appear. The pTau181 test can detect these early biological alterations in the blood, providing valuable information for timely and well-documented clinical decision-making.

When the test may be useful

The pTau181 test is a modern diagnostic tool that may contribute to:

• The evaluation of memory problems and cognitive impairment, particularly in individuals over the age of 55
• The reliable exclusion of Alzheimer’s disease when results are within the normal range
• The early identification of biological changes associated with Alzheimer’s disease
• The differentiation of Alzheimer’s disease from other forms of dementia
• Monitoring disease progression, always in collaboration with the treating physician

The test does not replace medical evaluation, and results must always be interpreted in conjunction with the patient’s clinical findings.

Reliability based on advanced technology
