(c) In making a determination under Subsection (b), the physician must use a test that is:
(1) consistent with the physician's good faith and reasonable understanding of standard medical practice; and
(2) appropriate for the estimated gestational age of the unborn child and the condition of the pregnant woman and her pregnancy.
(d) A physician making a determination under Subsection (b) shall record in the pregnant woman's medical record:
(1) the estimated gestational age of the unborn child;
(2) the method used to estimate the gestational age; and
