Similarly one may ask, how is fish test performed?
FISH testing is done by a pathologist. To do a FISH test the pathologist needs some blood or tissue from your cancer. This can be from a biopsy, blood sample or from when you had surgery to remove your cancer. In the laboratory, the pathologist attaches a dye and ultraviolet light to find and count the gene changes.
Secondly, how accurate is the fish test? It is always followed by the usual chromosome test. A normal FISH result is about 98% accurate in predicting that a baby will have a normal chromosome result. FISH is only offered in special circumstances that you can discuss with your doctor, or by payment of a non medicare-rebatable fee.
Accordingly, why is fish test done?
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.
How much does a fish test cost?
Each IHC test cost the laboratory $194.56, for which the standard reimbursement is $52.36, resulting in a $142.20 loss for each test performed. FISH testing is directly billed to the patient, at a cost of $794.00 per test.
