I notice the NBS specimen collection form has a box for CORD BLOOD. Does this mean that we can use cord blood rather than sticking the newborns?
NO! You should only submit cord blood to the NBS Program if a newborn has been transfused prior to the heelstick NBS collection. If you still have available a nonhemolyzed cord blood specimen that is also free of clots, you can spot it on the filter paper, identify the specimen as cord blood and report the specimen collection date and time to be the same as the birth date and time. The combination of a cord blood specimen (valid for the galactosemia and hemoglobin screens) and the 24-hour post-transfusion specimen (valid for the PKU and hypothyroidism screens) will allow you to obtain a complete screen for a transfused newborn.
