Critical values or “panic values” are considered “life-threatening” and must be immediately given in-person or by telephone to the ordering clinician or after hours coverage by the Medical Director or Associate Medical Director.
Alert values are medically important abnormal results which are not imminently life-threatening. These are also called or reported in-person to the ordering clinician or after hours to the Medical Director or Associate Medical Director. 
Critical or alert values obtained by testing at our reference laboratory will be called as soon as possible to the Health Center (work hours), or to the Medical Director or Associate Medical Director (after hours).
