Most Pathology departments NEVER issue preliminary reports on routine tests such as CBCs, Chemistry Panels, Lipid Panels, etc.
Usually the only preliminary reports issued by a Pathology department are tests that require a pathologist's interpretation. The majority of these are tissue reports, coagulation profiles, or electrophoresis testing. However, with HIV and HCV testing, any initial positives have to be confirmed with more specific methods (i.e. Western Blot or PCR) and usually have to be sent to a reference laboratory which can take a couple of more days.
Edit: Just thought of another type prelim report...any type culture. Micro may turn out a prelim....such as heavy growth of a gram negative rod, identify to follow.....or if they have identified the microorganism then they would turn out the id and have a sensitivity (what it's susceptibility is to certain antibiotics) to follow.
