(1) For newborns at birth weights of 1,500 grams or more, the required blood specimen must be taken between 24 and 72 hours of age.

(2) In the event the newborn is discharged from a health care facility prior to the third day of life, the blood specimen must be taken immediately before discharge and, in addition, if the newborn is discharged before it is 24 hours old:

(a) another specimen must be taken and submitted to the department's laboratory between the fourth and 14th day of the newborn's life; and

(b) the health care facility must:

(i) explain the reasons why it is of utmost importance to return for these tests; and

(ii) ensure that the parent or legal guardian of the newborn signs a statement assuming responsibility to cause a specimen to again be taken between the fourth and 14th day of life of the newborn and to submit it to the department for testing.

(3) If taking a specimen on any of the dates cited in (1) and (2) is medically contraindicated, the specimen must be taken as soon as possible thereafter as the medical condition of the newborn permits.
