What values for hematology should have delta checks to prevent preanalytical errors?
Preanalytical errors that might affect hematology testing include specimen mix-ups, improper specimen acquisition, and compromise of specimen integrity between when the specimen is acquired and when it is received in the laboratory. Delta checks, the process of flagging differences in specific analytes between consecutive analyses, are one way to detect such problems. Delta checks are effective in detecting some forms of preanalytical errors.
