The triple marker screen test is also known as the triple test, multiple marker test, multiple marker screening, and AFP Plus. It analyzes how likely an unborn baby is to have certain genetic disorders.
A triple marker screen test takes a sample of blood and detects the levels of AFP, HCG, and estriol in it.
The results of the triple marker screen test show the likelihood of an infant having a genetic disorder such as Down syndrome or spina bifida. Test results aren’t infallible. They merely show a probability, and may be an indication for additional testing.
