If you are an external healthcare provider with no access to Nationwide Children’s Epic system, submission of a completed Genetic Test Requisition Form is required. If you are an internal ordering provider with access to Nationwide Children’s Epic system, no requisition form is required; please place the lab order electronically in Epic. When ordering this test, please provide following information on the test requisition form: 1) Previously-tested Child's Name (Proband's Name), 2) Proband's Date of Birth, 3) Proband's Test Accession Number, and 4) Chromosome locus requested for testing.

Please collect whole blood in Sodium Heparin tube (green-top tube without gel separator). DO NOT use Lithium Heparin or other types of heparin tubes; check tube for proper heparin type.

Submission of a NaHep blood sample from the previously-tested child (proband) is required to be used as a positive control sample to provide the most accurate interpretation for the parental FISH result (no extra charge for proband sample processing/testing, except phlebotomy charge).
 

This test is available for biological parents (mother and father) of a proband who previously had a cytogenetic abnormality detected by Nationwide Children's Laboratory, such as a balanced or unbalanced chromosome rearrangement detected by chromosome analysis or FISH analysis, or a genomic gain or loss detected by microarray analysis. If the proband's cytogenetic abnormality was detected by an outside laboratory or if the patient to be tested is a family member of, but not biological parents of, the proband (e.g. grandparent, sibling, aunt/uncle, cousin, etc.), then please order a test called "FISH Analysis Only (test code: FISHON)" in place of this test.

Depending on the chromosome loci to be tested, special FISH probes may need to be ordered, which may result in longer result turn-around-time.

PLEASE NOTE: Small cytogenetic abnormalities below certain size may not be detectable by FISH analysis. If there are any questions regarding whether the proband's cytogenetic abnormality is detectable by FISH analysis or not, please call the Cytogenetic Laboratory (614) 722-5321 and ask to speak with a laboratory genetic counselor.
