Abstract
This invention relates to the measurement of analytes in dried blood samples. It has been discovered by measuring the hemoglobin in the dissolved dried blood sample, an estimate of blood volume may be made and used to make a correction for blood volume. Thus, analytes such as cholesterol, PSA, and other blood analytes can be more accurately determined. The invention further describes a blood collection device and disk material on which blood is dried to provide superior results.
