Amyloid, Tau and Neurofilament Profile
16 days
Simoa® assay or Lumipulse® assay
Tests included:
Amyloid-beta 42 (Aβ42), Plasma, CLEIA
Phosphorylated Tau 217 (p-Tau 217), Plasma, CLEIA
Neurofilament Light Chain (NfL), Plasma, CLEIA
BD- Tau, Plasma, SIMOA
Accredited Laboratory Partner
Weekly
The ATN (Amyloid, Tau, Neurofilament) profile is useful for determining the biological changes that are associated with Alzheimer's disease pathology.
EDTA Plasma
4 mL
K2 EDTA lavender-top/K2 Pink vacutainer tubes
Samples should be collected following overnight fasting. If patients are taking biotin (Vitamin B7), they should stop taking it 72 hours prior to sample collection.
Transport to the laboratory immediately following collection. If this is not possible, samples should be stored refrigerated (2-8° C)
