The minimum detectable dose of human ,Folic acid, is typically less than 6.25 pg/ ml. The sensitivity of this assay, or Lower Limit of ,Detection, (LLD) was defined as the lowest human ,Folic acid, concentration that could be differentiated from zero. It was determined the mean O.D ,value, of 20 replicates of the zero
Background: Vitamin B₁₂ deficiency is common among the elderly, and early ,detection, is clinically important. However, clinical signs and symptoms have limited diagnostic ,accuracy, and there is no accepted reference test method. Methods: In elderly subjects (n = 700; age range 63-97 years), we investigated the ability of serum cobalamin, holotranscobalamin (holoTC), total homocysteine (tHcy ...
