One death has been reported after biotin skewed a heart test
The US Food and Drug Administration knows of one patient who died after a falsely low troponin result on an affected test. That is one voluntary report, and the agency names no rate.
What the study found
One reported death, and no rate anywhere behind it
Troponin tells an emergency department whether someone is having a heart attack, and biotin can push it falsely low. The US Food and Drug Administration knows of one patient who died after low troponin results on an affected test. That is one voluntary report, and the agency names no rate.
The caveat · No workup ruled out another cause
Voluntary adverse-event reporting shows that something can happen, never how often. The death report carries no published clinical workup, so nothing in it rules out another cause. The agency's figures describe what it was aware of in 2019, in the United States, where assay availability and reagent generations have both moved on since.
