The traditional triple test for breast cancer diagnosis includes physical examination, mammography and aspiration cytology.
A minimally invasive screening test beside the triple test, or prior to biopsy, would lead to greater sensitivity.
The DS screening biomarkers currently implemented in the first trimester combined test or the second trimester triple test are derived from two tissues, namely fetal liver and placental trophoblasts.
Kusterer et al. [51] crossed Arabidopsis thaliana C24 and Col-0 genotypes to produce F7 recombinant inbred lines, then crossed these RIL to both parents and F1 in what is known as a triple test cross (TTC) design.
Although the reliability of the first trimester combined test is better than the triple test, both the DR and the FPR are still in need for improvement, and a lot of international effort has been put in improving both kinds of prenatal tests.
Initially, the most commonly used method for risk calculation was the second trimester triple test, which combines serum levels for alpha-fetoprotein (AFP), unconjugated estriol (uE3), and the free β subunit of human chorion gonadotrophin (fβ-hCG) with maternal age [1], [2].
