Serum HER-2/neu levels may not always indicate the presence or absence of malignant disease. The HER-2/neu value should be used as part of an overall clinical assessment that includes additional clinical evaluation and diagnostic tests. In metastatic breast cancer cases, 92% of patients having serum HER-2/neu of 37 µg/L or greater are tissue HER-2 positive, whereas only 27% of patients having values less than 37 µg/L are tissue HER-2 positive.
