<p>Apparatus (70) and device (10) for use in determining the concentration of a selected analyte in a body-fluid sample. The device includes a sample dispenser (12) designed to distribute a small-volume blood sample to multiple transfer sites (30, 34, 36, 38, 40), by capillary flow of the blood sample through sieving and distributing matrices (22, 26) which separate blood cells from serum as the sample fluid migrates toward the transfer sites. A test plate (44) in the device carries multiple absorbent test pads (48, 50, 52, 54), each containing reagent components for use in detection of a selected analyte. The test plate is mounted on the dispenser for movement toward and away from a transfer position at which the exposed surface regions of the pads are in contact with associated sample-transfer sites, for simultaneous transfer of sample fluid from such sites to the pads in the support. The apparatus is designed for use in transferring a uniform, quantifiable amount of sample fluid to each of the pads in the device.</p> |
