- Polymedco, the US distributor for OC-Auto, automated FIT (fecal immunochemical
test) system and OC-Light S FIT manual fecal immunochemical
test for colorectal cancer screening, has been awarded a five year contract from Los Angeles County, the company said.
Noninvasive screening tests for colorectal carcinoma include fecal occult blood tests and fecal immunochemical
techniques, pathologists found occult metastases in 10.5% of 326 women whose sentinel lymph nodes looked free of cancer on routine tests.
CHICAGO -- Although it is more expensive to administer, colorectal cancer screening with a fecal immunochemical
test is less expensive in the long run than a guaiac-based test because it detects more high-risk lesions and thus prevents more cancers, a cost-analysis study has concluded.
Citing a need for economical analytical methods for detecting trace levels of hazardous compounds in complex environmental and biological media, Van Emon (director for the immunochemistry program at the US Environmental Protection Agency, National Exposure Research Laboratory) notes that immunochemical
methods are capable of achieving very low detection levels and are particularly adaptable.
Divided into three parts, it deals with the relevant issues within the following broad categories: drugs potentially used in food-producing animals; the significance and control of drug residues in foods, and the microbiological, immunochemical
and physicochemical methods presently available in the field of drug residue analysis.
The protocols for producing and using antibodies and other immunochemical
techniques presented by Burns (Antibody Unit, Scottish Agricultural Science Agency) follow the same format as the rest of the Methods in Molecular Biology series, presenting step-by-step laboratory instructions, a brief description of the principle underlying the technique, lists of needed equipment and reagents, and tips on common pitfalls.
