Screening for translocation carriers
percept NIPT offers a rapid and non-invasive screening option for balanced translocation carriers.
How to arrange screening?
Pre-approval:
Our laboratory needs to review the translocation before we can offer screening.
We need:
- A chromosome report (G-banded karyotype) with balanced translocation details.
- If available, a chromosome microarray report if an unbalanced translocation was found in a previous pregnancy.
- And a description of how the translocation was identified in the family, if known.
Note: Carriers of Robertsonian translocations do not need pre-approval.
- Step 1
Email our lab with the pre-aproval information: [email protected]
In some cases, we may suggest that prenatal diagnosis is more appropriate than NIPT. - Step 2
Arrange a dating ultrasound. Ultrasound must confirm a singleton pregnancy. Translocation screening is not available in a twin or co-twin demise pregnancy.
- Step 3
Complete a percept NIPT test request form.
Please record the balanced translocation on the form. - Step 4
Direct your patient to a VCGS affiliated collection centre.
Blood must be collected at, or after 11 weeks of gestation.
