The law in Texas requires that only medically trained personnel—generally nurses, paramedics, and other medical professionals—be allowed to collect blood samples for testing purposes. The blood sample must be taken under the direction of a qualified medical professional and must be done using proper medical equipment, such as a sterile needle or syringe. The person taking the sample must wear gloves and must not contaminate the sample by coming into contact with it during the drawing process. Additionally, the person taking the sample must record the name of the person providing the sample, as well as their date of birth, and the time and date of the extraction. The sample must also be labeled with the name of the person providing it and be sent to a State-approved laboratory for evaluation.
