Quantitative measurement of cancer antigen 15-3
The CA 15-3 assay value, regardless of level, should not be interpreted as absolute evidence for the presence or absence of malignant disease. The CA 15-3 assay value should be used in conjunction with information available from clinical evaluation and diagnostic procedure.
