When collecting an infant's screening card, which should be collected first among O2 levels, bilirubin, and DNA?

The proper prioritization when collecting an infant's screening card necessitates considering the most critical screening tests for immediate health assessment. In this instance, oxygen (O2) levels should be collected first because they are essential for evaluating the infant’s respiratory status and ensuring that the baby is receiving adequate oxygenation, which is vital for survival and overall health in the early stages of life.

Monitoring O2 levels can quickly identify any immediate issues related to hypoxemia or respiratory distress that could require urgent medical intervention.

While bilirubin and DNA screenings are also important, they can be conducted after ensuring the infant's oxygen levels are stable. Bilirubin screens assess jaundice and potential liver function issues, and DNA tests can identify genetic conditions but are not as urgent as ensuring the infant's immediate oxygenation is stable. Collecting all at the same time may not be practical or effective in a clinical setting, as addressing critical conditions should take precedence.
