A bill to test newborns for potential heart defects is on its way to Governor Cuomo's desk.

The New York State Senate has unanimously passed a bill requiring pulse oximetry tests for all newborns in the state.  The bill was already passed in the Assembly.

Pulse oximetry is non-invasive, and tests the level of oxygen in a patient's blood.  The results could tip off doctors to the presence of a heart defect, permitting earlier diagnosis and treatment.
