The entire point of third-party lab testing is quality control. Any lab that can point to a full ISO/IEC 17025 accreditation for all services that they offer demonstrates that their own level of quality control is on point. It demonstrates that even though the state doesn’t require them to employ sensible standard operating procedures, they take it upon themselves to do so anyway. That attention to detail will absolutely carry over to the accuracy of the test results of your product and if you do things right, that’s all you should ever ask a lab to provide.
