CEA is a glycoprotein involved in cell adhesion with a molecular weight of 180 kDa. CE is delivered in high concentrations during fetal development. But it stops after birth. As a result, it is not usually present in the odor of healthy adults. The normal CEA range in non-smoking adults was less than 2.5 ng/mL and the CEAa primary cancer fetal antigen in smokers was less than 5.0 ng/mL, which was first described by Gold and Feldman as a specific marker for adult gastrointestinal cancer. Elevated CEA levels are also seen in patients with other types of cancer, such as breast cancer,Lung, urogenital and lymphatic tissues may also cause benign conditions with significantly higher than normal CE/ levels, including inflammation of the lung and gastrointestinal (G) tract and benign liver cancer. In colorectal cancer, the clinical use of CEA testing is to monitor response to treatment and to document the disease.
The colored line appearing in the control line area (C) is the internal positive program control. It confirmed sufficient sample size, adequate core suction and correct programming techniques.
The kit does not provide a control standard; However, it is recommended that positive and negative controls be tested as a good laboratory practice to confirm testing procedures and verify appropriate test performance
(Please refer to the illustration above)
POSITIVE:* Two distinct colored lines appear. One line should be in the control line region (C) and another line sh be in the test line region (T)
NEGATIVE: One colored lne appears in the control lineregion(C). No apparent colored line appears in the test line region(T).
INVALID: Control linefailstoappear.Insufficient specimen volume or incorrect procedural techniques are the most lik reasons for control line failure. Review the procedure and repeat the test with a new test device. if the problem pe discontinue using the test kit immediately and contact your local distributor.
