Thalassemia Mutation Testing Symptoms

THALASSEMIA MUTATION TESTING

DESCRIPTION – thalassemia mutation testing refers to the analysis of HBA1 and HBA2 genes for alpha-thalassemia and HBB gene for beta-thalassemia to understand the presence of the mutation and inheritance patterns that lead to thalassemia and other related genes

aminocytes

or cultured CVS – transfer these cultures to 2 flasks at 80 percent confluence

Maternal blood – transfer 5 ml of whole blood

STORAGE/TRANSPORT TEMPERATURE – room temperature for both

STABILITY –

Cultured

aminocytes

or cultured CVS – ambient: 24 hours

Maternal whole blood – ambient: 7 days; refrigerated: 1 month

SPECIAL INSTRUCTIONS – clinical history is mandatory
