Low ionized calcium (Ca; Hypocalcaemia, ionized): high death-coded share in the FDA AER plate

Signature read: Low ionized calcium (Ca; Hypocalcaemia, ionized)'s 44.8% death-coded share is among the highest in the openFDA reaction corpus. Report volume sits in the middle third of the reaction corpus. Death-coded share is upper-third: 39 of 87 reports (44.8% of named reports). Nearest volume peer: Bone marrow disorder NOS (±0 reports). Lead species Dog (46). Lead co-reported drug Maropitant Citrate (20).

Read these counts as reporting volume, not risk: per our methodology, A high death-coded share in FDA filings does not prove causation; co-reporting is voluntary temporal association only. Browse the full reactions index or the about page for how PlainBreed frames FDA CVM extracts.
