Offsite Collection Instructions
Obtain 20 mg to 30 mg of chorionic villus specimen (CVS) by the transabdominal or transcervical method. Transfer the CVS to a Petri dish containing transport medium. Using a stereomicroscope and sterile forceps, assess the quality and quantity of the villi, and remove any blood clots and maternal decidua. Transfer the CVS by using sterile technique to one or two 15-mL centrifuge tube(s) with 15 mL of transport medium. Send specimen refrigerated. Specimen cannot be frozen.
For University of Michigan registered patients, when chromosome analysis is requested to rule out certain conditions such as Turner syndrome (when indicated based on initial diagnosis) or suspected mosaicism, an additional cell count and/or special stains will be performed at an additional charge. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
