In the presence of ethynodiol diacetate the ethynylestradiol concentration in serum and saliva after oral administration was measured by a rapid radioimmunoassay method developed by the authors. By means of the saliva/serum quotient, and from the concentration of ethynylestradiol in the saliva samples, it was possible to infer the ethynylestradiol content of the serum. Attention is called to the relation between the quotient and time, which should be taken into account when values are calculated. 2, 4 and 12 h after oral administration, the saliva/serum quotients for an ethynylestradiol dose of 0.05 mg were 0.27, 0.76 and 0.40. respectively.
