In reporting every birth and stillbirth, physicians and others permitted to attend pregnancy cases and required to report births and stillbirths shall state on a separate sheet accompanying the birth certificate or stillbirth certificate, as the case may be, whether a blood test for syphilis has been made during such pregnancy upon a specimen of blood taken from the woman who bore the child for which a birth or stillbirth certificate is filed, and if made the date when such test was made, and if not made, the reason why such test was not made. Neither the fact that such a test was or was not made or was or was not required by law nor the result of any such test shall appear upon the birth certificate or be certified to any person for any purpose.
