False Positives & False Negatives
Newborn screening tests are only the screening tests and not confirmatory tests. According to a survey, screening tests can have a higher margin of error and be less valid than diagnostic tests, but they should have a very low false negative rate. It is estimated that, on the expanded newborn screening panel, only about one in fifty of every positive new-born screening test detects actual disease. It is also noted that the average rate of false positives can vary widely, and it depends on the conditions tested. One in ten positive tests for cystic fibrosis is a true positive result, while one in 100 or one in 200 positive tests for congenital adrenal hyperplasia is a true positive result. The unreliability of few newborn screening tests and lack of uniformity of newborn screening policies and procedures, across the globe, is likely to impede the growth of the market.
North America to Dominate the Market
North America is expected to hold the largest share of the newborn screening market during the forecast period, due to growing awareness regarding newborn screening tests. For instance, in the United States, over 4,000,000 screenings are performed annually.
In the United States, both federal and state governments make policies governing newborn screening, which is augmenting the demand for newborn screening tests in the region.
