For prenatal specimens only: If amniotic fluid (nonconfluent cultured cells) is received, amniotic fluid culture/genetic test will be added and charged separately. If chorionic villus specimen (nonconfluent cultured cells) is received, fibroblast culture for genetic test will be added and charged separately.
If this test is ordered in conjunction with CMAP / Chromosomal Microarray, Prenatal, Amniotic Fluid/Chorionic Villus Sampling or CMAPC / Chromosomal Microarray, Autopsy, Products of Conception, or Stillbirth, and no other molecular testing is ordered, test will be changed to PPAP / Parental Sample Prep for Prenatal Microarray Testing, Blood.
Ruling out the presence of maternal cell contamination within a fetal specimen
Required for all prenatal testing performed in Mayo Clinic Laboratories' Molecular and Biochemical Genetics laboratories
GENETICS TEST INFORMATION:
**Required in conjunction with molecular and biochemical prenatal testing only.**
If a prenatal specimen has already been submitted as part of another diagnostic test, a second prenatal specimen is not required. If a prenatal specimen has not yet been submitted, submit only 1 prenatal specimen.
ADDITIONAL TESTING REQUIREMENTS:
A maternal specimen and a prenatal specimen are both required.
-This test must be ordered on both the prenatal and maternal specimens under separate order numbers.
Specimen preferred to arrive within 96 hours of collection.
Patient Preparation: A previous bone marrow transplant from an allogenic donor will interfere with testing. Call 800-533-1710 for instructions for testing patients who have received a bone marrow transplant.
An interpretive report will be provided.
