New Technology in Diagnostics

FISH TECHNOLOGY
Fluorescence in situ hybridization. this technology is worked on H E R -2 genes by providing fluorescence , enabling pathologist to see and count the number in each cell.
one live example of DONNA HENAGIN was a strong, physically active young woman when she was diagnosed with breast cancer in April 2001.Surgery followed , including the removal of 37 lymph nodes. It was diagnosed with the help of the test called as

PATH VYSION , a gene based test developed by Abbott molecular ,confirmed that DONNA was amoung the estimated one in four breast cancer patients whose HER-2 gene was malfuntioning ,creating additional copies of it self.Abnormally high quantities of HER -2 gene associated with rapid tumor growth , resistance to therapy , and shorter the disease free periods and over all survival.
PATH VYSION tests based on FISH technology .Path vysion is approved for diagnosis,prognosis and clinical out comes

INTRODUCTION OF IMMUNOASSAY

INTRODUCTION OF IMMUNOASSAY-
An immunoassay is a test that uses antibody and antigen compexes as a means of generating a measurable results.An antibody:antigen complex is also known as an immuno-complex." Immuno" refers to an immuno response that causes the body to generate antibodies, and " assay" refers to the test.Thus , an immunoassay is a test that utilizes immunocomplexing when antibodies and antigens are brought together.

Immunoassays are different from the other types of laboratory tests,like colorimetric tests ,because they use antibody: antigen complexes to generate a signal that can be measured. In contrast , most routine clinical chemistry tests utilize chemical reactions between the reagent ( a solution of chemical or other agents) and patient sample to generate a test results.
