"A method that allows blood collection at home and that is simple enough to be performed independently, or by caregivers, would increase accessibility of these tests," Huber said in a statement. DBS(capillary) GFAP and DBS(venous) GFAP, NfL, and p-tau181 were found to be associated with MMSE, CDR, and amyloid status. ![]() DBS(capillary) p-tau217, but not DBS(capillary) p-tau181, were associated with the same measures in EDTA plasma.ĭBS(venous) GFAP, NfL, p-tau217, and p-tau181 were also associated with their counterparts in EDTA plasma. The researchers observed significant associations for DBS(capillary) GFAP and NfL with their counterparts in EDTA plasma. In a second study, Huber and colleagues obtained DBS(capillary), DBS(venous), and EDTA plasma, and neuropsychological measures for 77 memory clinic participants. DBS(capillary) and DBS(venous) were associated with amyloid status DBS(venous) NfL and p-tau181 were associated with Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), and amyloid. Significant associations were also seen for DBS(venous) GFAP, NfL, and p-tau181 with EDTA plasma levels. ![]() The researchers found that DBS(capillary) GFAP and NfL levels were associated with their counterparts in EDTA plasma. Neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and phosphorylated tau (p-tau) were measured by single molecular array. Hanna Huber, Ph.D., from the University of Gothenburg in Sweden, and colleagues collected capillary dry blood spot (DBS) and venous dry blood spot (DBS) as well as ethylenediamine tetraacetic acid (EDTA) plasma and neuropsychological measures from 43 memory clinic participants. ![]()
