Plasma β-amyloid1–42 reference values

Zecca et al. evaluated plasma β-Amyloid1–42 (Aβ1–42) concentrations in 245 cognitively normal subjects to determine reference values of Alzheimer's disease. [1]. The mean concentration of plasma Aβ1–42 increased by aging, although there was no significant difference in the mean concentration of plasma Aβ1–42 between the adult (35 to 64 years old) and the old (65 to 89 years old) groups. The authors presented 8.12 (95% CI 6.77–9.45) to 29.00 (95% CI 27.01–31.00) pg/mL as a reference value from the lower to upper limit.
