A parent brings a 2-week-old infant to a clinic for a phenylketonuria rescreening blood test. The test indicates a serum phenylalanine level of 1 mg/dL (60.5 mcmol/L). The nurse reviews this result and makes which interpretation?
It is inconclusive
it is negative
it requires rescreening at age 6 weeks.
It is positive
The Correct Answer is B
A. It is inconclusive
Explanation: A serum phenylalanine level within the normal range is considered conclusive in ruling out phenylketonuria. Inconclusive results typically occur when there are issues with the sample or testing process.
B. It is negative
Explanation:
A serum phenylalanine level of 1 mg/dL (60.5 mcmol/L) in a 2-week-old infant is within the normal range. In the context of phenylketonuria (PKU) screening, a "negative" result means that the phenylalanine levels are within the expected range, and there is no evidence of phenylketonuria.
C. It requires rescreening at age 6 weeks.
Explanation: If the initial screening result is within the normal range, rescreening at age 6 weeks may not be necessary for phenylketonuria. The timing and need for rescreening may vary based on local protocols and individual patient factors.
D. It is positive
Explanation: A positive result for phenylketonuria would indicate that the serum phenylalanine levels are elevated, suggesting a potential diagnosis of PKU. In this case, the result is negative, meaning there is no evidence of PKU.
