Opening laboratory problem: high ferritin is not a diagnosis

An adult male has serum iron 186 micrograms/dL, total iron-binding capacity 285 micrograms/dL, and ferritin 612 micrograms/L. The 08:15 specimen was collected after an eight-hour fast, with no iron-containing supplement documented in the preceding 24 hours. The specimen is not hemolyzed, icteric, or lipemic by local analyzer indices.

The calculated transferrin saturation is 65%, and the concurrently released chemistry panel shows mildly increased alanine aminotransferase. C-reactive protein is within that laboratory's reference range. These data support an iron-overload workup, but liver injury remains in the differential and the laboratory result does not measure tissue iron or organ injury.

The question is whether increased circulating iron availability, storage elevation, and genotype point in the same direction or whether ferritin is rising for another reason. Start by separating measured values from the calculated percentage and from clinical interpretation. Release each verified iron result with its units, flags, and local report language, not a disease label.
