LOINC description : The ratio of IgG to albumin clearances, the selectivity index, is useful in the diagnosis
and management of proteinuria. Both IgG and albumin levels are measured in serum and
urine and the selectivity index (SI) is determined where SI (uIgG/sIgG)/(uAlb/sAlb)
or (uIgG/sIgG * sAlb/uAlb).[PMID: 20921302];
