CA 15-3 ELISA

Key Features and Values

– Same sample type can be used across all assays to simplify inclusion into routine serology work-up
– Ready to use reagents reduces hands-on time for assay preparation
– Long shelf life cost-effective solution by reducing wastage due to expired kits
– Suitable for inclusion on automated plate systems simplifies scale-up of test volume
– Supported by a complete panel of assays for supporting treatment monitoring of several forms of cancer

Product Description

Immunoenzymatic colorimetric method for the quantitative determination of CA 15-3 concentration in human serum or plasma. CA 15-3 ELISA is intended for laboratory use only.

Scientific Description
CA-15-3, is an abbreviation for cancer antigen 15-3.  CA 15-3 levels are most useful in following the course of treatment in women diagnosed with breast cancer, especially advanced breast cancer.  CA 15-3 levels are rarely elevated in women with early stage breast cancer.  Cancers of the ovary, lung and prostate may also raise CA 15-3 levels.  Elevated levels of CA 15-3 may be associated with non-cancerous conditions, such as benign breast or ovarian disease, endometriosis, pelvic inflammatory disease and hepatitis.
Pregnancy and lactation can also cause CA 15-3 levels to rise.  CA 15-3 is most useful for monitoring patients postoperatively for recurrence, particularly for metastatic diseases.  96% of patients with local and systemic recurrence have elevated CA 15-3, which can be used to predict recurrence earlier than radiological and clinical criteria.  A 25% increase in the serum CA 15-3 is associated with progression of carcinoma.  A 50% decrease in serum CA 15-3 is associated with response to treatment.  CA 15-3 is more sensitive than CEA in early detection of breast cancer recurrence.
In combination with CA-125, CA 15-3 has been shown to be useful in early detection of relapse of ovarian cancer.  CA 15-3 levels are also increased in colon, lung and hepatic tumours.
