An ASIC block embedded in a host IC has a first clock domain with a first frequency of operation that is at least equal to a second frequency of operation of a second clock domain in the host IC but external to the ASIC block. The lancet integrated test elements each include a lancet configured to form an incision in tissue and a test element configured to analyze body fluid from the incision in the tissue. A decoder decompresses the compressed data according to a decoding scheme corresponding to the selected encoding scheme mode.
