Mothers to sue maker of 'infallible' baby gender test

Six New York City mothers are suing the maker of a baby sex test which touted its product as "infallibly accurate", saying the test results they received were wrong.

In papers filed in Manhattan Supreme Court, the women claim they received incorrect results from the US$275 (€197.84) Baby Gender Mentor test by Acu-Gen Biolab.

The suit says the test maker advertised its product as the "gold standard for prenatal gender detection", the New York Post reported.

The company's website says the test can determine a baby's sex as early as five to eight weeks' gestation.

Lawyer Barry Gainey says the lawsuit charges the product's makers and marketers with negligence and fraud, and seeks unspecified damages.
