A blood sample collection device can provide for collection, storage, amplification, and analysis of a blood sample in a simple, disposable device. The device can include a collection zone for drawing (e.g., via a needle array) or receiving a blood sample, a processing zone for storing and processing blood cells of the blood sample, and a filtration zone for selectively directing the blood cells of the blood sample to an array of wells within the processing zone while leading blood plasma away from the array of wells. Within the wells, which may be prepared to include materials for amplification and various assays, the blood cells can undergo amplification. Externally applied light and/or heat can facilitate amplification. A transparent or translucent window or portion of the collection device can allow an analysis device to take measurements of the array of wells without removing the sample.
