“Negative screen” for all disorders
The NBS Laboratory will send a “negative screen” report to the physician/midwife listed on the blood spot card and to the baby’s birth hospital.
"Repeat sample requested"
The NBS Laboratory will send a report to the physician/midwife listed on the blood spot card to request a repeat sample. A copy of the report will be sent to the baby’s birth hospital.
Usual reasons are:
- baby was less than 24 hours old at the time of collection;
- baby was less than 1,500 grams at birth;
- baby had a blood transfusion prior to collection of the sample; or
- sample was unsatisfactory.
“Positive screen” for one of the disorders
A positive screen does not mean that the baby has a disorder, but only that further testing is required. Please refer to the below three questions for further information.
