[lysozyme level in urine during pregnancy (author's transl)]

In the urine in adults lysozyme is only found in traces or not at all. During the course of a normal pregnancy however, lysozymuria is present. In early pregnancy lysozyme is excreted only in small amounts; between the 31st and 40th week of gestation a larger amount of lysozyme in excreted into the urine. In comparing the urine lysozyme level in the 40th week of gestation and one week post partum, a significant reduction in the lysozyme level appears in the latter. On the other hand, the lysozyme level in the maternal serum and the fetal cord blood shows no significant difference.
