Pediatrics · Neonatology: newborn screening tests

Sample item

Which pair of newborn screening tests is correctly matched?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Hearing by otoacoustic emissions; congenital hypothyroidism by TSH

Universal newborn hearing screening uses otoacoustic emissions or automated brainstem response. Congenital hypothyroidism is screened by TSH measured on cord blood or a heel-prick sample at 48 to 72 hours.

Option by option

  • A. Hearing by tympanometry alone; hypothyroidism by cord glucose

    Tympanometry alone does not screen for sensorineural deafness, and cord glucose is not for hypothyroidism.

  • B. Vision by fundus only; hypothyroidism by calcium

    These are not recognised screening pairs.

  • C. Hearing by otoacoustic emissions; congenital hypothyroidism by TSH (correct)

    Correct. OAE and TSH are the standard screening tools.

  • D. Hearing by Mantoux test; hypothyroidism by T3 only

    Mantoux testing detects tuberculosis, not hearing loss.
