Collect blood into a green top (sodium heparin) tube; invert several times to mix. A FISH test can be combined with chromosome analysis - only needs one tube (see Cytogenetics, FISH for Genetic Disorder). Please complete a MiChart test request and submit it with the specimen. A Cytogenetics Laboratory Requisition is available online at: http://www.pathology.med.umich.edu/handbook/Tables/UM_REQ_CYTOGENETICS….
Specimen transport should be arranged so that the specimen is received by MLabs the same day it is collected. Call for a STAT courier if necessary. Collect specimen in a green top (sodium heparin) tube. Invert the tube several times to prevent clotting. Send the specimen intact at room temperature as soon as possible. DO NOT CENTRIFUGE.
