Abstract
The availability of high quality reagents and new methodology have contributed to
overall improvements in the performance of immunoassays of human growth hormone in
recent years. Discrepancies between superficially similar methods do occur as a result
of the heterogeneous nature of the hormone itself. However, there is also evidence
of incorrect standardisation in widely used, commercially available assays. Careful
interpretation of growth hormone assays is still required, therefore, especially when
results from different laboratories are being compared.
