Question # 1: Is there a discrepancy between the Blood stix test and the microscopic results? If so, what could account for this? Answer: Yes there is a discrepancy between the Blood stix result (Large) and the Microscopic result (0-2/hpf.) This discrepancy is most likely caused by a high level of myoglobin, released from dying muscle as a result of the crush injury. Note, both Myoglobin and RBC's contain hemoglobin, and will thus react with the Blood stix test. However, only RBC's will be visible in the microscopic examination.
