Beckman Coulter 33205 Access CEA Calibrator (S0-S5) for Tumor Markers Assay Carcinoembryonic Antigen Test Specifications:

INTENDED USE: Beckman Coulter 33205 Access CEA Calibrator (S0-S5) for Tumor Markers Assay Carcinoembryonic Antigen Test

The Access CEA Calibrators (BSA matrix) are intended to calibrate the Access CEA assay for the quantitative determination of Carcinoembryonic Antigen (CEA) levels in human serum, using the Access Immunoassay Systems.

SUMMARY AND EXPLANATION: Beckman Coulter 33205 Access CEA Calibrator (S0-S5) for Tumor Markers Assay Carcinoembryonic Antigen Test

Quantitative Tumor Marker Assay calibration utilizing the Access CEA calibrator is the process by which samples with known analyte concentrations (i.e. assay calibrators) are tested like patient samples to measure the response. The mathematical relationship between the measured responses and the known analyte concentrations establishes the calibration curve. The mathematical relationship or calibration curve is used to convert RLU (relative light units) measurements of patient samples to specific quantitative analyte concentrations.

What are tumor marker tests (Carcinoembryonic Antigen Test)?

These tests look for tumor markers, which are sometimes called cancer markers. Tumor-markers are substances that are often made by cancer cells or by normal cells in response to cancer. For example, some tumor markers are proteins that certain cancer cells make in larger amounts than normal cells do. Changes in the genes and other parts of tumor cells can be tumor markers, too.

Certain tumor markers may be found in samples of body fluids, such as blood or urine (pee). Other tumor markers are found in samples of cells that are removed from a tumor during a biopsy.

Tumor marker tests are mainly used after you have a cancer diagnosis. The test results may help answer important questions about your cancer, such as:

  • How fast is the cancer growing?
  • What type of treatment is most likely to help?
  • Is the treatment really working?
  • Has cancer come back after treatment?

Not all cancers have known tumor-markers. And the tumor-markers that are known don’t provide perfect information. That’s because:

  • Some conditions that aren’t cancer may also cause high levels of certain tumor markers. Tumor marker tests can’t tell whether tumor markers come from cancer or from another condition.
  • Some people don’t make high levels of the tumor markers that are commonly found in their type of cancer.

But even with these limits, tumor marker testing can often give a more complete picture of your cancer when they are used along with the results of other tests and exams.

Tumor marker tests are mainly used to learn more about a known cancer. But in certain cases, they may be used to screen for cancer or to help diagnose the disease.

Tumor marker tests are most often used after you have a cancer diagnosis. When used with other tests, tumor markers may help:

  • Find out whether cancer has spread to other parts of your body (cancer stage)
  • Predict how fast your cancer may grow, the chance of recovery, and whether cancer is likely to return
  • Select the right treatment for your type of cancer. Some treatments work only with cancers that have certain tumor markers. Tumor markers that help plan treatment are also called biomarkers.

 

 

  • Monitor how well your treatment is working. If tumor marker levels go down, it usually means your treatment is helping.
  • Find any cancer that remains after treatment or cancer that comes back after treatment.
