Specimen Requirements
NOTE: This test is for products of conception specimens only.
Products of Conception Villi
Minimum 20 mg
Optimal >30 mg
Place in transport media provided; store and transport at room temperature - DO NOT FREEZE; DO NOT PUT IN FORMALIN. Do not send entire placenta to cytogenetics.
CMA testing on the direct specimen will depend on quality and quantity of available processed ("cleaned") villi.
Call for transport media or to arrange specimen delivery (tube to station 072, courier deliver or lab pick up). LAB phone: 410-955-3476; specimens will be received M-F, between 8am and 4:30pm
Products of Conception Tissue/Skin
Minimum 1 mm3
Optimal >10 mm3
Obtain recognizable fetal tissue and specify parts/organs. Place in transport media provided; store refrigerated and transport at room temperature - DO NOT FREEZE; DO NOT PUT IN FORMALIN. Do not send entire placenta to cytogenetics.
CMA testing on the direct specimen will depend on quality and quantity of available processed tissue.
Call for transport media or to arrange specimen delivery (tube to station 072, courier deliver or lab pick up). LAB phone: 410-955-3476; specimens will be received M-F, between 8am and 4:30pm
Products of Conception Fluid
Minimum 20 mL
Optimal >30 mL
Typically 10-15 mL for testing on direct (GA >17 wks) or cultured cells. To add additional testing would require an additional 10 mL per test, meaning >30 mL (if FISH requested with karyotype and CMA). Store and transport at room temperature - DO NOT FREEZE. Use multiple 15 mL centrifuge tubes or contact the lab for a sterile container.
CMA testing on the direct specimen will depend on size and quality of pellet.

Fetal Blood/Cord Blood
Minimum 1mL
Optimal 3 mL
Whole blood in a lavender top (EDTA); store and transport at room temperature - DO NOT FREEZE.
