Dear Colleague,

We inform you that the assays for serum markers for fetal trisomy 21 screening (in the 1st and 2nd trimesters) must now be performed on serum aliquoted into a drytube, prepared by your team.

Starting from July 18, 2024, and to ensure the best preanalytical conditions : samples with serum tubes containing a separating gel (not decanted) will no longer be accepted.

However, you can continue to collect samples from patients using a tube with gel, but it is imperative to centrifuge and decant it within 4 hours of collection to minimize potential interference with the free beta subunit of hCG (as recommended by  the analytical kit provider).

Please keep a second sample, frozen, within your serum bank.

For more details on prescription and transmission procedures, please refer to our online test catalog.
