FOB And TRF Rapid Test Kit Quantitative Determination Of WWHS FIA POCT Assay

【Product name】 FOB.pdf

Fecal occult blood (FOB) Rapid Test(Fluorescence immunoassay)

【Intended use】

This kit is used for quantitative determination of CEA in human whole blood, plasma and serum.

Carcinoembryonic antigen (CEA) is a tumor associated antigen, first described in 1965 by Gold and Freedman1. It is a cell-surface glycoprotein with a molecular weight of 180-200kD, that occurs in high levels in colon epithelial cells during embryonic development. Levels of CEA are significantly lower in colon tissue of adults, but can become elevated when inflammation or tumours arise in any endodermal tissue, including the gastrointestinal tract, respiratory tract, pancreas and breast.

An over expression of CEA protein has been detected in a variety of adenocarcinomas, including gastric, pancreatic, small intestine, colon, rectal, ovarian, breast, cervical and non-small-cell lung cancers. CEA is also expressed by epithelial cells in several non-malignant disorders, including diverticulitis, pancreatitis, inflammatory bowel disease, cirrhosis, hepatitis, bronchitis and renal failure and also in heavy smokers.

Therefore CEA should not be regarded as a tumour-specific marker for the screening of a general population for undetected cancers. However, the determination of CEA levels provides important information about patient prognosis, recurrence of tumours after surgical removal and effectiveness of therapy.
