R70-R79: Abnormal findings on examination of blood, without diagnosis
R78: Findings of drugs and other substances, not normally found in blood
The group of conditions classified under "Findings of drugs and other substances, not normally found in blood," refers to medical situations where a substance or drug that isn't usually present is detected in the patient's blood sample. These substances can be a wide variety of drugs or toxins, each with different potential effects on the body. Common causes include either accidental or intentional consumption, inhalation, or absorption of these substances. The symptoms can vary widely, depending heavily on the substance involved — they can range from minimal to severe, and may affect any body system. Disease progression also varies greatly, with some conditions being acute and others potentially developing into chronic conditions. It's important to note that these findings may serve as indicators of underlying substance abuse, poisoning, or exposure to toxic substances, and they can have significant implications for a patient's overall health status.
