These studies involve culturing of living cells; therefore, turnaround times given represent average times which are subject to multiple variables. Hard copy reports are generated following completion of a case. After specimen receipt, results are generally available in an average of 10 days. Stat results are generally available in an average of two to four days. A detailed report and a copy of a representative karyotype will follow. This test must be ordered using a Cytogenetic test request form 43097 or through your ARUP interface. Please submit the Patient History Form - Chromosome Studies with the Electronic Packing List. The form is available on ARUP's Web site, http://www.aruplab.com/home/consent_forms.jsp. 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 sample integrity is inadequate to allow culture growth. |
