Sickle Cell and Thalassaemia Screen
Description:
The Red Cell Protein Laboratory provides a comprehensive service for the detection of haemoglobin variants and thalassaemias.
Initial analysis is by HPLC which will screen for any haemoglobin variants and give an HbA2 level for beta thalassaemia identification.
Further tests will be performed depending on HPLC results, red cell indices and clinical details. This could include solubility test, acid electrophoresis or HbH bodies. For uncommon haemoglobin variants further analysis by iso-electric focussing can be undertaken.
All samples sent for analysis will get an interpretive comment relevant to the clinical details.
Molecular analysis can be undertaken by the Prenatal diagnosis section.
