Carcinoembryonic Antigen (CEA) is a tumor-associated antigen characterized as an oncofetal glycoprotein.1 CEA is expressed in a variety of malignancies, particularly pulmonary or gastrointestinal tumors (e.g. colon cancer, liver cancer and lung cancer). CEA normally occurs in fetal gut tissue with detectable serum levels essentially disappearing after birth.2,3

Therefore, elevated levels of CEA can be of significant value in the diagnosis of primary carcinomas.

In addition to qualitative assessment, CEA testing plays an important role in the monitoring of cancer patients. Clinical evidence indicates that CEA levels can serve as predictive markers in both pre- and post-treatment cancer. Progressive elevation of CEA may signal tumor recurrence 3-36 months before clinical evidence of metastasis. Persistent elevation of circulating CEA following treatment is strongly indicative of occult metastatic and residual diseases and deficient therapeutic response.4

The CEA Rapid Test Cassette (Whole Blood/Serum/Plasma) utilizes a combination of anti CEA antibody coated particles and anti-CEA antibodies to detect elevated levels of CEA in whole blood, serum or plasma. The minimum detection level is 5ng/ml.

1.Before opening the pouch, let it reach room temperature. Take out the test cassette from the sealed pouch and use it within an hour.

2.Put the cassette on a flat and clean surface.

For Serum or Plasma samples:

Keep the dropper upright and transfer 1 drop of serum or plasma (about 25μL) into the sample well of the test cassette, then add 1 drop of buffer (about 40μL) and start the timer. See the illustration below.

For Venipuncture Whole Blood samples:

Keep the dropper upright and transfer 2 drops of whole blood (about 50μL) to the sample area, then add 1 drop of buffer (about 40μL), and start the timer. See the illustration below.

For Fingerstick Whole Blood samples:

To use a capillary tube: Fill the capillary tube and transfer about 50μL of fingerstick whole blood sample to the sample area of the test cassette, then add 1 drop of buffer (about 40μL) and start the timer. See the illustration below.

3.Wait for the colored line(s) to show up. Read the results at 5 minutes. Do not interpret the results after 20 minutes.
