Tex. Family Code § 262.010

(a) If during an investigation by the Department of Family and Protective Services the department discovers that a child younger than 11 years of age has a sexually transmitted disease, the department shall:

(1) appoint a special investigator to assist in the investigation of the case; and

(2) file an original suit requesting an emergency order under this chapter for possession of the child unless the department determines, after taking the following actions, that emergency removal is not necessary for the protection of the child:

(A) reviewing the medical evidence to determine whether the medical evidence supports a finding that abuse likely occurred;

(B) interviewing the child and other persons residing in the child's home;

(C) conferring with law enforcement;

(D) determining whether any other child in the home has a sexually transmitted disease and, if so, referring the child for a sexual abuse examination;

(E) if the department determines a forensic interview is appropriate based on the child's age and development, ensuring that each child alleged to have been abused undergoes a forensic interview by a children's advocacy center established under Section 264.402 or another professional with specialized training in conducting forensic interviews if a children's advocacy center is not available in the county in which the child resides;

(F) consulting with a department staff nurse or other medical expert to obtain additional information regarding the nature of the sexually transmitted disease and the ways the disease is transmitted and an opinion as to whether abuse occurred based on the facts of the case;

(G) contacting any additional witness who may have information relevant to the investigation, including other individuals who had access to the child; and

(H) if the department determines after taking the actions described by Paragraphs (A)-(G) that a finding of sexual abuse is not supported, obtaining an opinion from the Forensic Assessment Center Network as to whether the evidence in the case supports a finding that abuse likely occurred.

(b) If the department determines that abuse likely occurred, the department shall work with law enforcement to obtain a search warrant to require an individual the department reasonably believes may have sexually abused the child to undergo medically appropriate diagnostic testing for sexually transmitted diseases.
