Section 7552 - Performance of testing(a) Genetic testing shall be of a type reasonably relied on by experts in the field of genetic testing and performed in a testing laboratory accredited by either of the following:(1) The AABB, formerly known as the American Association of Blood Banks, or a successor organization.(2) An accrediting body designated by the Secretary of the United States Department of Health and Human Services.(b) A specimen used in genetic testing may consist of a sample or a combination of samples of blood, buccal cells, bone, hair, or other body tissue or fluid. The specimen used in the testing need not be of the same kind for each person undergoing genetic testing.(c) Based on the ethnic or racial group of a person undergoing genetic testing, a testing laboratory shall determine the databases from which to select frequencies for use in calculating a relationship index. If a person or a local child support agency objects to the laboratory's choice, the following rules shall apply: (1) Not later than 30 days after receipt of the report of the test, the objecting person or local child support agency may request the court to require the laboratory to recalculate the relationship index using an ethnic or racial group different from that used by the laboratory.(2) The person or local child support agency objecting to the choice of laboratories under this subdivision shall do either of the following: (A) If the requested frequencies are not available to the laboratory for the ethnic or racial group requested, provide the requested frequencies compiled in a manner recognized by accrediting bodies.(B) Engage another laboratory to perform the calculations.(3) The laboratory may use its own statistical estimate if there is a question of which ethnic or racial group is appropriate. The laboratory shall calculate the frequencies using statistics, if available, for any other ethnic or racial group requested.(d) If, after recalculation of the relationship index pursuant to subdivision (c) using a different ethnic or racial group, genetic testing does not identify a person as a genetic parent of the child, the court may require a person who has been tested to submit to additional genetic testing to identify a genetic parent.Added by Stats 2018 ch 876 (AB 2684),s 14, eff. 1/1/2019.
