Implementation of thyroid function tests algorithms by clinical laboratories: A four-year experience of good clinical and diagnostic practice in a tertiary hospital in Greece

Hospital-based laboratories can safely apply a generally accepted TFTs algorithm on physician's orders without any compromise in diagnostic/therapeutic accuracy, thus achieving significant direct cost-reduction and increased physician awareness on current TFT ordering practices. Such an approach, combined with collaboration with ordering physicians, can safeguard patients from the consequences of low-value care practices.
