For the qualitative detection of CEA in human serum/plasma or whole blood
The CEA Gold Rapid Screen Test (RST) is a chromatographic
immunoassay for the detection of cancer embryo antigen (CEA) in
human serum or plasma.
A correlative antigen to intestinal cancer, it can be used to assay
the curative effect and prognosis of colon cancer. To some
malignant cancer or pulmonary carcinoma outside of the intestine,
the concentration of CEA in serum is a high. In clinical, CEA is
taken as an early index to colon cancer, carcinoma of stomach,
rectal cancer, cancer of esophagus and relapse of cancer after the
The CEA RST is a chromatographic immunoassay (CIA) for the
detection of CEA in human serum or plasma. Specific antibody
against CEA re-coated onto membrane as a capture reagent on the
test region. During the test, specimen is allowed to react with the
colloidal gold particles, which have been labeled with other
specific antibodies. If CEA present, a pink colored band will
develop on the membrane in proportion to the amount of CEA
presented in the specimen. Absence of this pink colored band in the
test region suggests a negative result. To serve as a procedural
control, a pink colored band in the control region will always
appear regardless the presence of CEA.
This RST is convenient, easy to read, sensitive, rapid and credible
diagnostic kit that suitable to all levels of hospitals and medical
and hygienical institutions.
