relative concentration ratios , obtained by dividing the bile to serum level ratio for each protein by the corresponding ratio for albumin , were 310 , 1.6 , 1.0 , 0.82 , and 0.54 for iga , igm , albumin , transferrin , and igg respectively , suggesting that both iga and igm are selectively secreted into bile .
