Question

Quizplus · Accepted Answer

Newborn screening using mass spectrometry identifies certain single-gene disorders by detecting unusual metabolites or metabolic imbalances. This is because certain genetic disorders can affect the body's ability to break down or produce certain molecules, leading to an accumulation or deficiency of certain metabolites that can be detected through mass spectrometry.
