What does FISH stand for in medical terms?
Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in human cells, including specific genes or portions of genes. Because a FISH test can detect genetic abnormalities associated with cancer, it’s useful for diagnosing some types of the disease.
What is a medical FISH test?
Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person’s cells. This test can be used to visualize specific genes or portions of genes. FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene.
What does a positive FISH test mean?
FISH testing usually returns one of two results: positive or negative. Positive means your breast cancer cells make too much HER2 and your doctor should treat you with drugs that target that protein. Negative means the protein isn’t involved in the growth of your tumor.
What is the FISH technique?
Fluorescence in situ hybridization (FISH) is a laboratory technique for detecting and locating a specific DNA sequence on a chromosome. The technique relies on exposing chromosomes to a small DNA sequence called a probe that has a fluorescent molecule attached to it.
What are the 4 FISH principles?
John Christensen created this philosophy in 1998 to improve organizational culture. The central four ideas are: “choose your attitude”, “play”, “make their day” and the “present moment”.
Can FISH test wrong?
Accuracy and limitations. Prenatal interphase FISH testing is highly accurate, with reported false-positive and -negative rates usually less than 1%.
How do I read my FISH test results?
How your doctor interprets this test is as follows:
- A result of 0 is negative.
- A result of 1+ is also negative.
- A result of 2+ is considered equivocal (uncertain).
- A result of 3+ is positive.

What are the 4 steps of the fish philosophy?
The central four ideas are: “choose your attitude”, “play”, “make their day” and the “present moment”.
What does fish mean in the Medical Dictionary?

What is a fish test and what does it do?
Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in human cells, including specific genes or portions of genes.
What is the definition of a fish mouth?
1. Any of numerous cold-blooded aquatic vertebrates characteristically having fins, gills, and a streamlined body and including the bony fishes, such as catfishes and tunas, and the cartilaginous fishes, such as sharks and rays. 2. Any of various jawless aquatic craniates, including the lampreys and hagfishes.
What kind of cancer can a fish detect?
FISH also can identify chromosomal abnormalities in leukemias, including chronic lymphocytic leukemia (CLL) cells, some of which are associated with aggressive forms of the disease.
