A method for the early detection of a pregnancy comprises determination of EPF in the blood or urine or in a biochemical derivative of the blood or urine of pregnant women, by measuring the influence of EPF on the production of electronically excited states or radicals, especially oxygen radicals, or their secondary products, in leukocyte or cell line preparations. The method can also be used to determine gonadal tumors. |
