DNA Storage With MCC

DNA Storage With MCC – Test Content

Test Name: DNA Storage With MCC
Category: Molecular Genetics / Prenatal Genetics

Overview:
DNA Storage With MCC combines DNA preservation with Maternal Cell Contamination (MCC) assessment. DNA storage allows extracted DNA to be retained for potential future genetic testing, while MCC testing helps determine whether a prenatal sample contains maternal DNA that could affect interpretation.

Why is it performed?

• Helps preserve valuable DNA for possible future genetic investigations.
• MCC assessment is particularly relevant for prenatal samples such as amniotic fluid or chorionic villus samples (CVS).
• Helps identify maternal DNA contamination that may interfere with fetal genetic test interpretation.
• Useful when additional genetic testing may be required later.

Sample:
Depends on the associated genetic investigation; prenatal testing may involve amniotic fluid/CVS along with a maternal blood sample for MCC assessment.

Key Benefits:
✔ DNA preserved for future testing
✔ Supports accurate prenatal genetic analysis
✔ Helps assess maternal cell contamination
✔ Useful for follow-up molecular/genetic investigations

Clinical Significance:
MCC testing is an important quality-control step in prenatal molecular diagnostics because maternal DNA can potentially contribute to or complicate the genetic profile obtained from a fetal specimen.

Note: DNA retention duration depends on the laboratory's storage policy and test requirements. Some genetic laboratories offer defined storage periods such as 2–5 years or longer.
