Errors in health care services may cause irreversible harm in some cases. Medical errors are a threat to the welfare and health of the patient and their family and should be prevented. The majority of medical errors have little impact on human health, but some of them cause huge losses. This report describes a case of laboratory error in amniocentesis during pregnancy in which uncertain test result caused anxiety and lots of concern for the family. Inappropriate approach to medical error causes more errors to happen. Studies have shown that appropriate reporting and shift from traditional to systematic approach are important factors in reducing the frequency of medical errors.
