What happens if the result is positive or abnormal
Haemoglobinopathy results are not telephoned. A detailed report will be sent out in when available.
General additional information
Blood transfusion may make interpretation unreliable. If a haemoglobinopathy cannot be characterised then further studies may be undertaken.
This assay detects the presence of the abnormal haemoglobins, HbC, HbD, HbE, HbS and other rarer variants. The quantitation will be reported as appropriate.
The haemoglobinopathy screen is sometimes referred to as a Thalassaemia Screen.
