Cytogenomic Molecular Inversion Probe Array FFPE Tissue - Products of Conception
Ordering Recommendation
Use to detect copy number alterations and loss of heterozygosity in FFPE specimens from products of conception.
New York DOH Approval Status
Specimen Required
Fetal autopsy or products of conception.
FFPE Fetal tissue: Transport ten slides, each with 5 um unstained sections or four 20 um scrolls or tissue block.
OR FFPE villi: Transport one H&E stained slide and ten slides, each with 5 um unstained sections or tissue block.
New York State Clients: Transport 1 FFPE block or 10 slides (10 um each).
Preferred transport temp: Room temperature. Also acceptable: Refrigerated. Ship in cooled container during summer months.
Specimens fixed or processed in alternative fixatives or heavy metal fixatives (B-4 or B-5). Decalcified tissue
If multiple specimens (blocks or slides) are sent to ARUP, they must be accompanied by one of the following: an order comment indicating that the ARUP pathologist should choose the specimen most appropriate for testing (e.g., "Choose best block"), or individual orders for each sample submitted. A Pathologist Block Selection Fee (ARUP test code 3002076) will be added to orders that utilize the first option. If multiple specimens are sent to ARUP without a request for pathologist block/slide selection or individual orders, they will be held until clarification is provided.
Counseling and informed consent are recommended for genetic testing. Consent forms are linked above.
New York Clients: informed consent is required with submission.
Room temperature: Indefinitely; Refrigerated: Indefinitely; Frozen: Indefinitely
