A properly collected and handled specimen is critical to quality test results. Test Information Sheets provide comprehensive instructions, including:
Information on Turn Around Time (TAT): The TAT published on PHO test information sheets is an estimate that may vary for some tests or during public health emergencies, outbreaks or exigent circumstances. The TAT does not apply to tests added on to existing specimens or on hold awaiting information to continue testing. The TAT for tests sent to reference laboratories is dependent on the reference laboratory testing schedule and timing. “Days” refers to business days and excludes weekends and holidays. Public Health Ontario disclaims all warranties whether expressed or implied in respect of the information, including the TAT provided herein.
