Quanterix Corporation (NASDAQ: QTRX), a company expanding the limits of exploration with ultrasensitive biomarker detection, today announced the validation of a laboratory developed test (LDT) to quantitatively measure phospho-Tau 181 (pTau-181) in plasma as an aid in diagnostic evaluation of Alzheimer’s disease (AD). Quanterix’ LDT – the first pTau-181 plasma test released for clinical use in the U.S. – is a quantitative immunoassay intended for the measurement of pTau-181 concentration in human plasma. The test results are intended to be used in adults presenting with cognitive impairment who are being evaluated for AD and must be interpreted in conjunction with other diagnostic tools.
