The tests performed are ‘screening’ tests and are different from diagnostic tests. The screen cannot detect all inborn errors of metabolism. The test may fail to identify some babies with these disorders, and some babies may test positive who may not actually have the disorder. Sometimes babies who are born prematurely, who are underweight at birth, or who may have received a blood transfusion can test positive, but not have the disorder. Your baby’s doctor may want to repeat the test or do other testing to check the results.
Not all affected infants will be identified through screening. The accuracy of screening tests depends on various factors, including the way the specimen is collected, infant’s age at testing, birth weight, gestational age, feeding type, transfusion status, the presence of co-existing illness or medical conditions and medications. If an infant with normal screening test results has symptoms of a disorder, or medical problems associated with metabolic disorders, further diagnostic tests may be necessary, regardless of the baby’s newborn screening results. While newborn screening has proven to be reliable in the early detection of some metabolic, endocrine and hemoglobin disorders, as with any laboratory tests, false positive and false negative results are possible.
