A Diagnostics & Imaging Week

Six New York City mothers are suing the maker of a baby sex test that 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 $275 Baby Gender Mentor test by Acu-Gen Biolab (Lowell, Massachusetts).

The suit says the test maker advertised its product as the "gold standard for prenatal gender detection." The company's web site says the test can determine a baby's sex as early as five to eight weeks' gestation.

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