The Carcinoembryonic antigen (CEA) Rapid Test (Whole Blood/Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of human carcinoembryonic antigen (CEA) in human whole blood, serum, or plasma specimens. This kit is intended for use as an aid in the diagnosis of various cancers.
Carcinoembryonic antigen (CEA) is a tumor-associated antigen characterized as an oncofetal glycoprotein of approximately 200,000 molecular weight with Beta electrophoretic mobility, a single protein chain of about 800 amino acids, and 50-80% carbohydrate composition. CEA was first present as a specific antigen for adenocarcinoma of the colon. More recent studies have demonstrated CEA presence in a variety of malignancies, particularly those involving ectodermal tissues of gastrointestinal or pulmonary origin. Small amounts have also been demonstrated in secretions from the colonic mucosa. Additionally, CEA-like substances have been reported in normal bile from non-icteric patients. CEA testing can have significant value in the monitoring of patients. Persistent elevation in circulating CEA following treatment is strongly indicative of occult metastic and/or residual disease. A persistent rising CEA value may be associated with progressive malignant disease and poor therapeutic response. A declining CEA value is generally indicative of a favorable prognosis and good response to treatment. Measurement of CEA has been shown to be clinically relevant in the follow-up management of patients with colorectal, breast, lung, prostatic, pancreatic, ovarian, and other carcinomas. Follow-up studies of patients with colorectal, breast and lung carcinomas suggest that the preoperative CEA level has prognostic significance.

Sample Collection&Storage
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
Bring tests, specimens, buffer and/or controls to room temperature (15- 30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification. For best results, the assay
should be performed within one hour.
Using the provided disposable pipette, transfer 1 drop of whole blood, serum or plasma specimen to the specimen well (S) of the cassette, then add 1 drop of
buffer and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result window.
As the test begins to work, color will migrate across the membrane.
2. Wait for the colored band(s) to appear. The result should be read within 15 minutes. Do not interpret the result after 20 minutes.
