Serum calcium (Ca) levels of 2000 samples (690 cases) throughout pregnancy, labor and puerperium were determined by the Clark-Collip method. In the present stadies, some interesting results were obtained. 1. Generally speaking, serum Ca levels of pregnant women were in lower levels than those of nonpregnant, and they were the lowest in the eighth month. 2. They were getting lower during labor and got the lowest levels at 2 hours after delivery. 3. There was no significant difference in levels of serum Ca between term deliveries and overterm. 4. Cord serum Ca showed higher levels than maternal serum Ca, and there was a correlation between the former and the latter. 5. There was no difference between serum Ca levels in umbilical artey and umbilical vein. 6. Not only maternal but umbilical serum Ca levels had no correlation with body weight of the new born. 7. The decrease of serum Ca in pregnancy was covered a little by administration of Ca agents. 8. The legs-cramp-symdrome during pregnancy got well by drugging calcium. 9. There was no difference in levels of serum Ca between normal pregnancy and threatened abortion. 10. The cases of excessive vomitting during pregnancy showed the same levels as in normal pregnancy, but serum Ca levels of the severe toxemia of pregnancy were decreased definitely. 11. Serum Ca levels were decreased after Cesarian section as after gynecological operations.
