There are very accurate tests for measuring liver and heart iron. These are MRI's and SQUID tests. Both are far superior to serum ferritin tests and biopsies and pose none of the danger of a biopsy, which normally is very safe, but in rare instances can cause random problems such as blood clots.
In our group we have members who represent an Australian company, Resonance Health, which offers the FerriScan imaging technology to hospitals that have compatible MRI machines, which includes most newer models. The technology is offered at no cost to hospitals, and the only costs involved are the MRI fees and the fee Resonance charges for each analysis of the scan. The scan is perhaps the most accurate measure of liver iron concentrations available.
FerriScan has regulatory clearance in Australia, Europe and the USA and is available as a commercial service.

Andrew was kind enough to sit in on our last group chat when we were still at MSN and provided answers to everyone's questions. I have seen scan results using FerriScan and they are quite impressive, showing exactly where and how large iron deposits are in the liver.
It is recommended that thal patients have routine MRI scans to determine the true concentration of iron in their livers. Blood serum ferritin tests do have their value and do give a relative idea of how much iron is in the blood but they don't tell you the condition in the organs. Knowing the iron levels in the liver is of far more use than serum ferritin levels. Scans or biopsies are necessary for this. This is an essential part of comprehensive care plan for thalassemics.
