A processing fee will be charged if this procedure is canceled at the client's request, after the test has been set up, or if the specimen integrity is inadequate to allow culture growth. The fee will vary based on specimen type.
It is recommended that all FISH studies be done in conjunction with routine cytogenetic analysis. (Refer to appropriate Chromosome Analysis test for order instructions).
If cell pellets or dropped cytogenetic slides are submitted, processing fee will not apply.
This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface.
