A result far enough outside its reference range is flagged critical, and a
critical result raises a safety alert.
What counts as critical
The bounds come from the reference range on the result: at or below half of
the lower bound is critically low, at or above one and a half times the
upper bound is critically high. A potassium range of 3.5–5.1 mmol/L, for
instance, makes 1.7 critically low and 7.7 critically high. There is no table
of fixed thresholds — every result is judged against its own range, so a result
with no range can never be critical.
Where an alert appears
Medication alerts share the banner. Those come from your medication list and
conditions rather than from a lab value, and are explained in
Contraindication Warnings.What to do
A result that is merely low or high is not an alert. It is shown with its flag,
counted in the interpretation, and is the kind of thing the food
recommendations are for.
Limits
An alert is worked out from the number on the report and nothing else. ClapDiet
does not know your history, your symptoms, or whether the value is expected for
you. Adding conditions to your profile changes the medication and dietary
guidance you see; it does not move the critical bounds.
When in doubt, treat the alert as real and ask a clinician.Related Articles:
