Abstract
For blood or other physiological fluid sample collection kits that use filter paper to collect the sample, the performance of the kit and associated analytical method can be improved by using a material having properties which are superior to those of standard filter paper or modified filter paper routinely used in standard biological assays. Certain materials currently available for uses other than blood collection, storage, or transport have properties that are advantageous as employed in assays of biological fluids, including the use of specific cellulose blotting materials for collecting blood samples for hemoglobin or hemoglobin A1c monitoring.
