Abstract
In this review the usefulness of the measurement of erythrocyte Na+/Li+ countertransport (Na+/Li+ CT) activity is evaluated. In particular, the association between enhanced erythrocyte Na+/Li+ CT activity and essential hypertension, hyperlipidaemia and diabetic nephropathy is discussed. The conclusion of this review is that elevated erythrocyte Na+/Li+ CT activity is associated with essential hypertension and hyperlipidaemia. A relationship between Na+/Li+ CT activity and diabetic nephropathy is less evident. Despite a significant link of Na+/Li+ CT activity with hypertension and hyperlipidaemia, the diagnostic significance of Na+/Li+ CT activity is low. This is due to the large overlap between the results of control subjects and patients. The factors that contribute to this broad range are discussed in detail.
