When genetic testing is ordered under AS 25.20.050, test results must be served on all parties to the action at least 20 days prior to any hearing or trial at which such results may be introduced into evidence. The test results must be accompanied by an affidavit, prepared by a qualified person, which addresses the qualifications of the affiant and the validity of the testing procedures and results. Any objection to the test results must be filed and served no later than 10 days before the hearing or trial. If no timely objection is filed, the test results are admissible as evidence of paternity at the hearing or trial without the need for foundation testimony or other proof of authenticity or accuracy.
