Estimation of hematocrit in filter paper dried bloodspots by potassium measurement: advantage of use of perimeter ring samples over circular center sub-punch samples.

Abstract

BACKGROUND Quantitative assays using dried filter paper bloodspots (DBS) may be adversely affected by hematocrit (HCT) as an unknown variable. Studies have demonstrated the utility of the measurement of potassium (K) from DBS punches to estimate HCT. Because there is significant accrual of RBCs at the DBS perimeter, we investigated whether K measurement… (More)
