What are they?
Blood disorders which affect the structure of haemoglobin
Babies who receive a blood transfusion prior to Sickle Cell screening will require a repeat test at 4 months post transfusion. This alsoincludesintrauterine transfusions.
Therefore it is strongly recommended that a pre-transfusion blood spot specimen is obtained from all babies in SCBU or NNU for SCD screening.
Obtain one spot on admission to unit and mark as pre-transfusion. Then send to lab with the 5 day sample if baby receives a transfusion
