(a) Except as otherwise provided in subsection (c) of this section, a record of a genetic testing expert is admissible as evidence of the truth of the facts asserted in the report unless a party objects to its admission within 14 days after its receipt by the objecting party and cites specific grounds for exclusion. The admissibility of the report is not affected by whether the testing was performed:
(1) Voluntarily or pursuant to an order of the court or a support-enforcement agency; or
(2) Before or after the commencement of the proceeding.
(b) A party objecting to the results of genetic testing may call 1 or more genetic-testing experts to testify in person or by telephone, videoconference, deposition or another method approved by the court. Unless otherwise ordered by the court, the party offering the testimony bears the expense for the expert testifying.
(c) If a child has a presumed, acknowledged or adjudicated father, the results of genetic testing are inadmissible to adjudicate parentage unless performed:
(1) With the consent of both the mother and the presumed, acknowledged or adjudicated father; or
(2) Pursuant to an order of the court under § 8-502 of this title.
(d) Copies of bills for genetic testing and for prenatal and postnatal health care for the mother and child which are furnished to the adverse party not less than 10 days before the date of a hearing are admissible to establish:
(1) The amount of the charges billed; and
(2) That the charges were reasonable, necessary and customary.
