Newborn Screening Tests and Immediate Care in Korea

Common Newborn Screenings

Upon birth in Korea, hospitals offer several screening tests. While some are standard (and covered by Korean National Insurance), others—like G-Scanning—are elective and often unfamiliar to international parents.

1. Metabolic Disorder Test (Newborn Screening Test)

This test is performed using a blood sample drawn between 48 and 72 hours after birth. It aims to detect metabolic issues that are asymptomatic at birth but can cause permanent developmental damage if left untreated.

• Detectable Conditions: Includes Phenylketonuria (PKU), Congenital Hypothyroidism, Maple Syrup Urine Disease (MSUD), Galactosemia, and various Acidemias or Deficiencies.

• Outcome: Most conditions identified are treatable through early dietary management.

Results: Typically available within one week.

2. Hearing Test

A non-invasive screening for permanent hearing loss, which affects roughly 3 in 1,000 babies.

3. Blood Type Test

Routinely included in the newborn screening panel.

4. G-Scanning

A blood test used to identify potential chromosome abnormalities or genetic disorders that may not be apparent at birth but could manifest later.

• Focus Areas: Learning disabilities, developmental delays, autism spectrum disorders, epilepsy, and hereditary conditions.

• Cost: This is not covered by National Health Insurance and costs approximately 250,000 KRW.

• Decision: Parents can choose to opt-in for this test before or after birth during their hospital stay.
