Newborn Screening Program Data
Newborn Screening Program Data
Screenings help find and identify individuals who do not have any symptoms but may be at risk of having a disease or condition. Diagnostic testing, also called confirmatory testing, is done after screening identifies an individual as possibly having a condition. Testing will confirm or rule out the diagnosis. In other words, screenings identify, and testing confirms.
Presumptive positive (pre-positive) screens are any screen that resulted potentially positive for a condition. Pre-positive screens require additional testing through a diagnostic test to confirm or rule out the diagnosis. Sometimes the blood collected from the initial screen is not of good enough quality to be analyzed. If this happens, a repeat screen will need to be collected.
Confirmed positive screens include all presumptive positive screens that were confirmed to be positive for the condition through confirmatory testing.
The reports below display the total number of confirmed positive cases of conditions in a given year.
Please note that these totals only reflect the number of cases that were confirmed through confirmatory testing. This does not include presumptive positive cases that did not receive confirmatory testing or were ruled out.

Sometimes, babies with abnormal newborn screens will be found to be carriers of the condition trait. This means that the while the infant will most likely not be affected personally by the condition, they may pass the trait to their children in the future. Additionally, if two people with the same condition trait have children, there is an increased risk of the child having the true condition. It is important for individuals who are carriers of newborn screening conditions to understand their trait status.
The table below lists the number of infants identified as carriers of a newborn screening condition within the given year.
NBS Condition Carrier/Trait Data
| NBS Condition Trait/Carrier Type | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | 2023 |
|---|---|---|---|---|---|---|---|
| Cystic Fibrosis Carrier | 253 | 218 | 206 | 152 | 205 | 175 | 170 |
| Hemoglobin S Trait (Sickle Cell Carrier) | 1019 | 1027 | 1043 | 1050 | 1105 | 1075 | 1056 |
Initial screens are the first newborn screening collected from a baby. Repeat screens are any additional newborn screenings that are performed on the baby after the initial screen. Screening totals show how many of each type of heel stick screen (initial or repeat) happened each year. Repeat screenings are usually performed if the initial screen is presumptive positive.
Presumptive positive (pre-positive) screens are any screen that resulted potentially positive for a condition. Pre-positive screens require additional testing through a diagnostic test to confirm or rule out the diagnosis. Sometimes the blood collected from the initial screen is not of good enough quality to be analyzed. If this happens, a repeat screen will need to be collected.
The table below shows the number of initial screens, repeat screens, total screens (combined initial & repeat) and percentage of all screens that were repeats within a given year.
Newborn Screen Type: Initial vs. Repeat
