R89: Abnormal findings in specimens from other organs, systems and tissues

The group of conditions classified under "Abnormal findings in specimens from other organs, systems and tissues" encompasses a range of possible discoveries during the medical investigation of patient samples. These findings could stem from various organs, systems, or tissues, and signify that something is not typical or is unexpected according to medical standards. The abnormalities may manifest in different forms, such as unexpected cell changes, presences of foreign bodies, or unusual levels of certain substances, like enzymes or hormones. The causes for such findings are diverse, and can be due to diseases or disorders, infections, exposure to harmful substances, or genetic variations. Common symptoms would depend on the specific abnormality, but they often drive the initial investigation into the specimens. Progression and affected systems also largely vary, depending on the underlying condition that caused the abnormality.
