Section 7555 Of Chapter 2. Blood Tests To Determine Paternity From California Family Law Code >> Division 12. >> Part 2. >> Chapter 2.
7555
. (a) There is a rebuttable presumption, affecting the burden
of proof, of paternity, if the court finds that the paternity index,
as calculated by the experts qualified as examiners of genetic
markers, is 100 or greater. This presumption may be rebutted by a
preponderance of the evidence.
(b) As used in this section:
(1) "Genetic markers" mean separate genes or complexes of genes
identified as a result of genetic tests.
(2) "Paternity index" means the commonly accepted indicator used
for denoting the existence of paternity. It expresses the relative
strength of the test results for and against paternity. The paternity
index, computed using results of various paternity tests following
accepted statistical principles, shall be in accordance with the
method of expression accepted at the International Conference on
Parentage Testing at Airlie House, Virginia, May 1982, sponsored by
the American Association of Blood Banks.
