The process of histological examination is completed in three stages. The 1st stage involves the receipt of the samples for examination. The samples are registered in the laboratory logs and coded for tracking purposes during the examination and later stages. The correct and complete filling out of the referral form, as well as the instructions for transport, packaging, and labeling of the sample, is the responsibility of the referring doctors/providers. The 2nd stage involves the macroscopic processing of the samples, which marks the beginning of the medical procedure during which the macroscopic description of the sample is made. When the materials concern large organs or preparations, additional sections are selected and taken according to the guidelines and areas of interest. The chemical processing of the tissues follows, embedding them in paraffin blocks, microtoming them, and placing them on microscope slides, staining them with hematoxylin/eosin, covering them, and checking their quality. The slides are separated by case along with the corresponding referral form. Finally, each case (slides – referral form) reaches the pathologist, and the microscopic examination (study of the slides under a light microscope) is conducted. The microscopic examination is a qualitative, not quantitative, method, and is based on the medical study and assessment of the tissue images, not on the measurements of a machine. The data from the above examination are evaluated along with the clinical history (referral note), the macroscopic findings, and the results of additional tests that the patient has undergone (laboratory and imaging results), and a decision is made regarding whether additional auxiliary tests are necessary. Based on all the above, the pathologist arrives at the pathological/histological diagnosis. The 3rd stage includes actions related to the communication of the diagnosis and the archiving of the material. The final report is dictated by the doctor, recorded by the secretary, corrected and validated by the doctor, and then the attending physician is informed. Archiving refers to reports/histological findings, slides, and paraffin blocks.
