Traditional biochemical screening for aneuploidies and neural tube defects


Tailored Solutions to Support Your Screening Needs

Find cost-efficient, customizable and reliable biochemical screening solutions for aneuploidies and other pregnancy-related complications to support population-based prenatal screening.


1st Trimester DBS

Our dried blood spot assay provides the same clinical performance as first trimester serum assays and supports easier access to screening in regions where storage of serum samples can be a challenge.

1st Trimester QUAD

1st Trimester QUAD

We offer four CE-marked assays — PAPP-A, free hCGß, PlGF and AFP — for first trimester screening of Down syndrome for enhanced performance; the same PIGF assay can also be used for pre-eclampsia screening.

FMF - Approved

2nd Trimester AFP

The human alpha-fetoprotein (AFP) marker offered as part of the first trimester Down syndrome screening panel can also be used to screen for neural tube defect screening in the second trimester.


FMF - Approved

All of our prenatal screening algorithms, instruments and reagents are approved by the Fetal Medicine Foundation.


More choice. Better care.

Whatever your preferred biochemical screening model, our assays offer tailored solutions that meet all your screening needs in the first and second trimester.

First Trimester

Full support for earlier detection.

Together, our four CE-marked assays — PAPP-A, free hCGß, PlGF and AFP — provide accurate screening for aneuploidies without the need for ultrasound Nuchal Translucency (NT) measurement.

Achieve more with serum screening.

In the second trimester, our assay solutions support all second trimester screening models: 2T Double, 2T Triple and the 2T Quad test. In addition to screening for the common aneuploidies, our solutions can facilitate the early detection of other conditions; our AutoDELFIA® hAFP kit, for example, can be used to determine neural tube defects such as spina bifida.

Empower your screening strategy 

The LifeCycle software provides a complete data management solution for your laboratory, but at its heart is the our Risk Calculation Engine. It has been designed to perform multiple complex algorithms and manage a variety of screening models. The software is also user-configurable, meaning users can enter their own parameters based on MoM values to optimize performance for the local population.
