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.
• Rapid test cassette with desiccant

• Package insert
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
Sample Collection&Storage
• The CEA Rapid Test is intended for use with human whole blood, serum, or plasma specimens only.
• Only clear, non-hemolyzed specimens are recommended for use with this test. Serum or plasma should be separated assoon as possible to avoid hemolysis.
• Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8°C for up to 3 days. For long term storage, specimens should be kept below -20°C. Whole blood collected by venipuncture should be stored at 2-8°C if the test is to be run within 2 days of collection. Do not freeze whole blood specimens. Whole blood collected by fingerstick should be tested immediately.
• Containers containing anticoagulants such as EDTA, citrate, or heparin should be used for whole blood storage.
• Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.
• If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents.
• Icteric, lipemic, hemolysed, heat treated and contaminated specimens may cause erroneous results.
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.
2. Transfer 3 drops of whole blood/serum/plasma to the specimen well (S) of the device with the provided disposable pipette, and start the timer.
OR
Allow 3 hanging drops of fingerstick whole blood to fall into the center of the specimen well (S) of the test device, and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the membrane.
3. If the test fails to migrate across the membrane after 1 minute, add 1 drop of buffer to the specimen well (S).
4. Wait for the colored band(s) to appear. The result should be read at 15 minutes. Do not interpret the result after 20 minutes.
