Okla. Stat. tit. 10, § 10-7700-503

Retesting.

A. Genetic testing shall be of a type reasonably relied upon by

experts in the field of genetic testing and performed in a testing

laboratory accredited by:

1. The American Association of Blood Banks, or a successor to

its functions;

2. The American Society for Histocompatibility and

Immunogenetics, or a successor to its functions; or

3. An accrediting body designated by the federal Secretary of

Health and Human Services.

B. A specimen used in genetic testing may consist of one or

more samples, 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 individual undergoing

genetic testing.

C. Based on the ethnic or racial group of an individual, the

testing laboratory shall determine the databases from which to

select frequencies for use in calculation of the probability of

paternity. If there is disagreement as to the testing laboratory’s

choice, the following rules apply:

1. The individual objecting may require the testing laboratory,

within thirty (30) days after receipt of the report of the test, to

recalculate the probability of paternity using an ethnic or racial

group different from that used by the laboratory;

2. The individual objecting to the testing laboratory’s initial

choice shall:

a. if the frequencies are not available to the testing

laboratory for the ethnic or racial group requested,

provide the requested frequencies compiled in a manner

recognized by accrediting bodies, or

b. engage another testing laboratory to perform the

calculations; and

3. The testing laboratory may use its own statistical estimate

if there is a question regarding which ethnic or racial group is

appropriate. If available, the testing laboratory shall calculate

the frequencies using statistics for any other ethnic or racial

group requested.

D. If, after recalculation using a different ethnic or racial

group, genetic testing does not conclusively identify a man as the

father of a child under Section 27 of this act, an individual who

has been tested may be required to submit to additional genetic

testing.
