Monitoring effectiveness of dietary therapy in patients with hyperphenylalaninemia
This test is not sufficient for follow-up for abnormal newborn screening results or for establishing a diagnosis of a specific cause of hyperphenylalaninemia
This test provides evaluation of patients with hyperphenylalaninemia or monitoring effectiveness of dietary therapy.
This test does not provide sufficient follow-up for abnormal newborn screening results because other causes of hyperphenylalaninemia (eg, BH4 deficiency) cannot be excluded by this test alone.
