Laboratory results include which of the following?

Laboratory results primarily consist of specific analyses performed on biological samples to aid in diagnosis and treatment. This includes a complete blood count (CBC) and pathology reports, which provide critical information regarding a patient’s health status, such as blood cell levels and tissue characteristics.

A complete blood count measures various components of blood including red and white blood cells, platelets, and hemoglobin, giving insight into conditions like anemia or infections. Pathology reports, on the other hand, offer results from tissue biopsies or cell samples, helping to identify diseases such as cancer and inform subsequent medical decisions.

Radiology reports, while essential in the overall medical picture, pertain to imaging studies (like X-rays or MRIs) rather than laboratory tests. Physical examination notes are clinical observations made by healthcare providers but do not qualify as laboratory results. Likewise, discharge summaries provide a recap of a patient's hospital stay and treatment but do not fall under the category of laboratory results.

Thus, the correct answer highlights the laboratory-specific results that directly impact diagnosis and treatment processes.
