Ordering Code 8327
Test Name SNP Microarray - POC (Reveal)
Preferred Specimen Preferred nonfixed tissue or products of conception (POC)/ placental villus biopsy; unstained tissue slides; formalin-fixed paraffin-embedded tissue (For formalin fixed paraffin embedded blocks or slides, test number will be updated to Microarray-Products of Conception (POC) Reveal(R)
FFPE [51197]. If <8 mg nonfixed tissue is received, sample will be assessed to run on the Oncoscan Microarray platform, and test number adjusted as necessary)
Preferred Container Sterile container containing sterile Ringer's lactate or
Hanks' balanced salt solution or transport medium provided by the cytogenetics laboratory. If no transport media is available, sterile isotonic saline can be used for transport. Do not use urine containers for shipping.
Collection Instructions Pertinent medical findings must accompany test request form
If prior NIPT studies have been performed, include copy of the report

Aseptically obtain a small piece of fetal tissue that does not appear necrotic. If specimen is a POC, placental villi or membranes may be the only fetal-derived tissue available, and an effort should be made to submit these tissues rather than maternal decidua.
