Genetic sequencing for β-Thalassemia mutations in prenatal samples
Amniotic fluid or chorionic villus sample (CVS) or cultured amniocytes or cultured villi Cultured cells are required for testing Direct specimens can be submitted but a culturing fee may be included Maternal and paternal Blood samples submitted on separate test request forms for 252827 (charges may apply) Maternal Blood should also be ordered for Maternal Cell Contamination [511402] required for fetal testing
10 to 15 mL amniotic fluid or 20 mg CVS or two T25 flasks cultured amniocytes or two T25 flasks cultured villi and 7 mL whole blood for parental samples.
Sterile plastic conical tube or two confluent T-25 flasks for fetal testing, lavender top (EDTA) or yellow-top (ACD) tube for blood.
